Only one I need. I’ve been using this app for years. I mean I do t know how long. 6 or 7 at least. It was free and the developer has this pop up asking for a review and I always ignore it but this time I thought, man, this has helped me so many times I really owe it to them. I am a dairy and pork farmer. I use this app to estimate breeding and gestational periods. Using the knowledge of animal breeding and days to labor you can calculate time periods that you should be expecting them to breed or drop babies.

Excellent app, for regular and normal users. This app serves its basic purpose, to add subtract times and dates, and does it well. Power users, as some reviewers here are should not crap their review because it didn't do it for them, the publisher didn't advertise it as a power app, so some perspective is needed. All in all its a clean little app, helps me enough to not bother going on a web page to calculate dates and times. Keep up the good work.

Does just what it says it does - simply!. I've been using this app now for over a year and can't say enough about it. It does exact what it says it does - calculate time and dates. But it does so correctly and simply. I use it for my job, where I need to calculate the end dates of contracts and when invoices are due. It's perfect for me! Thank you so much!

Great app for many time difference calc. or exact age.. Great basic app for figuring out many time calculations. From figuring out your exact age to finding out exactly when a holiday or birthday is, it does it all and much more, I’m still discovering new functions as I go, I still haven’t used all of them.

Perfect time calculator app!. I'm a Production Test Engineer for an Aerospace Engineering company that manufactures electronics for the Space Industry. We test the electronics in thermal vacuum chambers which requires dwells & stabilization times at different temperatures and vacuum pressures some of which are several days. This app is just what I was looking for to help calculate the dwell times. I've used several other apps, some of which were pretty good but once I found this app it's been my go to app!

Love this tool for every day life but I wish. it included a field to calculate 'Weeks'. This is such a cool app and helps me because I work administratively in healthcare and my boss tells me to bring a patient back in 6 months, I can so easily calculate the date they should return which makes me even more efficient in my boss' eyes. Always a plus!! I will recommend to all my coworkers.

Works and looks great.. Very nice app. It works smoothly, and the UI is very pleasant. I use this for calculating dates for ERISA compliance, and it's accurate and much quicker than those bogged down website calculators. Only wish is a "done" button or something when putting in range to adjust variables. Right now, just tap outside the number pad, but a button would still be nice.

I Love This App. I am planning my family's Disney vacation and on their website they say that reservations can be made up to 499 days out for rooms, 180 days out for restaurant reservations and 60 days out for this and 90 days out for that. This app makes it so much easier to figure out what days I need to do what. Thanks So Much!!!!

Essential for Travelers!. This app will immediately replace a few other apps I use to keep track of time for my job. It's definitely worth trying out!! The only thing I could see improving so far would be adding a "Done" function when the user adds input. There's currently nothing to tell the user how to save their input- only figuring out that they need to tap somewhere on the screen to continue. Still an excellently written and visually appealing app!!

Great app. This is a great app with a clean and usable interface. I need to often calculate x days from today, or from another date. The dateranger feature is great. Simple and fast. I wish I could save some presets like 60, 90 days, etc so I would just see them when I opened the app but that would just make a great app even better.

NOT for Pilots! DON’T buy it until it is fixed.. This app is not for pilots. We need to add multiple flights together and produce total hours and minutes. This app will not do this. If you want to add three series of flights together such as 21:48 + 18:33 + 9:19 = 49:40. This app will only add two of these trips together. When you do this you get a product in DAYS, Hours & Minutes. If you want to add three times you need to write down the product of the first two times then input this time and add the third time. The product of these times is again produced in DAYS, Hours & Minutes. This is totally in adequate for pilots who are trying to add total hours and minutes together and DON’T want them converted to days, hours & minutes. The input method is clumsy too. In order to input 21:48 + 18:33 you need to first select the hours field then input 21, then select the minutes field and input 48, then select the next hours field and input 18 and finally select another minutes field and input 33. When all of that is done you get a product that is in DAYS, hours and minutes and hopefully you don’t need to add any other times because the process will need to start all over again. This app needs to have a “lite” version so you can see the manner in which the app works before you commit to purchasing it.

Instantly tells you when things will occur.. I looked at and downloaded many apps before I found this one. I use it mostly for figuring out the day and time when upgrades and battles will end on Clash of Clans. I also work as a project manager and having this tool is as easy as a calculator for figuring out what day, hour and time something will occur. Thanks to the developer for creating it. I love it.

An important app for people who need to keep track of time. I really love having this app. It does many different tasks that I need that are time related. Probably the only thing missing would be a more robust, fully functioning time calculator. However, for the many different jobs it does, it's still outstanding.

20,000 Days on Earth. Back in 1997 I used my HP 48gx calculator to to tell me what day I will be 20,000 days old. Today I received an email calendar reminder I sent to myself 19 years ago. It was like a message in a bottle, long forgotten from a very different life I was living. This app enables you to forecast dates and times, and much, much more. Great app! Get it.

Worth the money!. I use this calculator at work all the time. I have to calculate business days from different dates though out the day. This app makes it so convenient. The only improvement I can think of is a feature that includes business days AND federal holidays. Other than that it’s perfect!

it's a useful utility. Not bad, it's a useful utility. Should have an option to calculate differences without time. Should have an option to have the date difference be inclusive. Should have an option to copy results to the clipboard, you can do it with a few extra steps by sharing the result, do the copy, then cancel the share. Cumbersome but doable. Using the date ranger, there is no 'done' button, you have to touch outside of the boxes, not intuitive.

Great!. Thank you for developing a time and date calculator that does everything I need and then some. I work in a laboratory, and I regularly need to add time, usually in hours, to a given date and time. For example, I might need to calculate when to take my samples out if I put them in tomorrow at 8 am, and the testing time is 3000 hours. I've looked at dozens of apps, and this is the only one I've found that can do this. And it even accounts for daylight savings time.

Great App. Compared to other similar free apps: Great. Compared to at least one other $0.99 app: Great. I got my money's worth for this app that I just purchased today and did a couple test run scenarios. [The $0.99 app has under a similar date ranger feature an option for weeks, which would be nice for this app also.] However, over all, this app is a great app. Great job.

Works well, fills in a need for time conversion, I'm keeping it.. This is a very utilitarian, straight to the point app for time conversion. And who hasn't needed that at one point or another. No fluffy graphics or sound (thankfully) and no screen spam, popups, etc. so far. (Screen spamming apps get 1 star) I'm keep it, it will be useful, and will live alongside my other unit conversion apps)

Almost perfect. Fantastic app. The only things I'd like to see is being able to convert the number of hours to days on the travel distance sheet. I'd also like to see calculations saved in sessions so I don't have to scribble down on paper the results of the calculations. I'd also like to see more conversion options on the birthday tab. I think we could really benefit if we could get milliseconds in general as a conversion option as well. The more exacting the different modes of calculating time and length would go a long way to making this app the best on the market.

I love this app!. What a great tool, almost everything could want to calculate RE: time Thomas has included in this great little app! If I could create an app, this is pretty much exactly what I would have tried for. I esp. love the time travel tool, since doing simple math in my head is impossible these days! Thanks Thomas for a great app!

Use This App When You Need to Know Time Forward or Backward. I use this app for my job. I need to know the date 30, 60, 90, and 120 days from now. At times, I need to know how many days have passed since last contact with a customer. This app provides me with the answers I need. I would give more than 5 stars if I could

Deadlines are my life!. I really like the app. I am a child protective investigator for the state of Florida and am held to a number of different deadlines in each of my cases. This app easily lets me determine what days each of my case deadlines falls in by simply inputting the date the case came in. I can find what the date and time is 2 days, 14 days, 28, 30, 50, 55 and 60 days. I need to explore the app further but I would love to see if I can create templates for timeframes and have the app coordinate with my calendar to send me alerts and reminders... It may be there.. I need to research further. Love the app! MW

Great beginning. This app is very similar to another app that I used to calculate date and time differences. That app was discontinued and the functionality of this app is the closest I’ve found so far. The main difference is look and ease of use. The other app looked like a calculator and all the functions are buttons on the calculator. It was very easy to calculate the date and time of 1,000 hours later or subtracting 1 date from another to get to the difference in time. This app is so close, and so far, the best I’ve found.

Great time/date calculating app!!. I find myself using it quite frequently to figure out all sorts of time differences between two reference points. Before we can post certain items on our website our algorithms need 200 days of data points. This app lets me check total days and weekdays-only for the 200 day metrics. Love it!!

Platinum Standard App Here!. hands-down, I can say this is easily one of the most functionally useful and user-friendly, no-BS apps I've ever downloaded. Wasn't quite sure how I would use some of the functions (actually most of them) at first, so they didn't immediately strike me as useful things to have included. By giving myself the time I needed and the app the chance it deserved, I quickly realized how powerful the other included functions were that I had originally wrote off. The more you tinker with them, the easier it is to start to envision how they could make your day-to-day life easier, ...or at least a bit more thought-out. Thank you so much to the developer for this gift to the sea of iOS-using humanity. As Borat says... HIIIII FIIIIIVE!!!!

Excellent Time Management App.. Time management is a very important skill to have on the day to day, and this is one of the apps that helps me along the way. I consider this to be one of those “tools you never knew you needed until you see it”. I use this mainly for delegating my minutes and hours and help me stick to a schedule, but it can be used for many other purposes, I’d imagine. The layout is nice and it’s fairly simple to use. The iPhone X support is also promising because it means the developer will likely be updating the app and maybe adding new features in the future. I certainly hope so. It’s well worth the .99 cents.

Great app for what I use it for, but I wish you could add more than 2 times together at once. Great app and it's even better that it is free, but I wish you could add more than 2 times together simultaneously. As it is now, I have to add the 2 times together then put that result on the left side and then add the next time on the right.

Exactly what I needed. I spent quite some time sorting through the subpar alternatives on the App Store, searching for a simple app to calculate date ranges quickly, so I was relieved to find this app. It proved to be exactly what I needed: it does one thing and does it well--date calculations. That is the definition of well-designed software

Hmmm. The only thing I can’t figure out how to do, is let’s say my customer gives me an invoice on a particular date let’s say today. And I tell him 10 to 12 weeks is when the product will be shipped. How do I figure out 10 to 12 business weeks on your app when you only show days, or days of the week but not a selection for business weeks. That’s why am giving it a three

Just The Thing. As a writer, I'm always in the market for apps that can provide the one thing or two that you just don't realize would be handy until you see it. In terms of my writing life, this app is a fantastic tool for fact-preparation or even fiction brainstorming - and in terms of being just another dude with an iPad...well, it's simply wickedly cool. I know, I know...you're sayin' to yourself right now: "What would I really need this for?" Trust me...if you think you don't want this utility...just try it. You'll find out. This is one of about three apps I've ever used/owned/experienced that compelled me to MAKE A POINT of contacting people I know to see if they had heard about it yet. Kudos to the developer. Seriously.

Multiple Apps in One. This 9 in 1 app is a good start. Overall it's interesting to calculate the different time differences for travel, future dates, age, etc. I like that it can calculate hours and days worked on a project. The Time Converter is okay. There should be a way to identify the 2 or 3 locations instead of "Point A" and "Point B". Not sure what the function is of "Today" and "Now" along side the Time and Date. Enter a future date or time, the Today and Now remain unchanged. Hope there's an update in the works.

Time Zone Difficulty. Got the app to help with time zones and planning with the East Coast. I live in Alaska and am frequently on the phone with people on the east coast. The time zone support is hard to use. Scrolling through the list of every possible city/zone is both annoying and difficult. Perhaps, the app could add a feature where the user can define favorite time zones, and those could always be displayed. Also, a map or something similar might help with zone selection.

Work Days could be refined. It is nice that there are defaults. But there should be a setting that allows ine to select the days that they work, in the event that they do work on Saturdays or their schedule is not exactly Monday through Friday as assumed with the way that the app is coded now. What if I only work Monday AND Friday instead of Monday THROUGH Friday? I hope you get the important point I am trying to make.

Good, could be better. Very useful. As a pilot adding up hours in a log book it would be much more useful if one could add a list of hours and minutes and get a sum expressed in hours and minutes. I imagine this would also be useful for truck drivers and such. Workers creating an employment log need to add many hours and minutes and arrive at a sum expressed in the same terms. A very clever app, hopefully in evolution to a more useful one. Still very helpful as it is.

Great app. I work recovering video from surveillance systems and they usually have inaccurate date and time sometimes a few minutes sometimes days it's a pain trying to figure out the correct date and time this app figures it out on the spot thank you very much.

Best so far. The best date calculator I've seen so far. Neat. Easy to understand. I'll be getting rid of my other date apps. Only drawback is having to use a wheel for locations for calculations. That can be a little tedious. Wouldn't mind jazzier colors but it works well. Make country selection quicker and easier and then it would get 5 stars.

Interesting and Useful. Downloaded as a freebie. I work in a hospital as a case manager. Close to 100% of use will be devoted to adding days to current or a recent date. Spot on. The interface is on two levels. I like the type of menu selection scheme the developer chose. No mistaking what you want. Once in the calculator, it is equally clean in design and clear in purpose. I'd like to see a "Done" button on the number board to close. Touching off the keyboard accomplishes the same. Notwithstanding, I'd prefer a close and commit key. I certainly won't remove a star in the rating because of my quirky preference. This app is updated and improvements are likely to keep coming. That means this "Time Machine" will be sitting next to my computer at work. Good job.

Amazing!!!!!! 😀. THIS APP IS A LIFE SAVER. It has saved me so many times. It's really good for the price (IDK if it is free or costs money) lol :) it can calculate the number of hours from one time to another. It's great if you want it for just everyday life or want to calculate how many hours you have worked for a basic job. It's not the best if you are a rocket scientist thou. Or a pilot but I'm not ether of those so 5 STARS FOR ME WHOOP WHOOP!!!!

A very easy to use tool. Time math problems are tough for me, but this app simplifies the math. It enables me to calculate time math problems related to my job. Whereas I previously used paper and pencil, which took too much effort, I can now quickly breeze through time math problems with ease. Many thanks for this useful tool.

INVALUABLE!. I have used this marvelous app on many occasions & consider it a great tool for research! On the "fun" side, I may include the number of minutes a family member has been alive, or the number of seconds spent on a particular project. On the "serious" side, I use this app at least weekly doing various research or writing projects. Thankful for the ease & accuracy of Date & Time Calculator!!!

Very handy. I use this far more than I expected. The functionality it provides is comprehensive. I agree with others the interface is awkward (mostly just a few too many taps in certain places or looking twice for the specific function I have in mind), but it is not a showstopper. Not every app has a perfect UI. I'm cheering for the developer as he refines this app, and in the meantime I am grateful for the time it saves when calculating time.

Every Tool I Need, ++PLUS++ Some GREAT NEW TOOLS I Never Even Thought To Use!!. Every Tool I Need, ++PLUS++ Some GREAT NEW TOOLS I Never Even Thought To Use/look for!! Great App; it works as advertised, has a simple & intuitive interface, and is extremely useful to have within quick reach. I tried a few 'similar apps', but none had nearly as many features, or the simple interface. Good Job; keep up the good work!! :-) 😃

Very nice app. Unique. Beautiful and simple interface. I only need it for one thing, so I really don't like looking at all the other options and scrolling through them. Please, please if it's not too much trouble, add a setting that has sliders where we can "turn on/off" (make visible/hide) certain features. That would be awesome!! I use the add/subtract function for my equine breeding class to quickly calculate when our mares will come into heat, ovulate, etc. So thank you for developing this!!!

Time Calc. This app is most useful to me on multiple fronts. First is tracking my time on a number of projects that I am involved with. In addition to my "normal" work, I have been studying numerology for over 40 years. This app dramatically reduces the time I would ordinarily spend converting time into the format I use. I will keep a eye out for apps coming from your direction. Keep up the stellar work.

Great tool for on the go. I need to have this feature and usually use on on my desktop but when I’m on the go I haven’t had the ability to get dates a specific day a certain number of days after a specific date... this app works so well and gets me exactly what I need!

It's not broken who cares about pilots. Get another app. This app is great does way more Than I even expected and the review message was legit. First time I ever didn't get annoyed when it popped up. Great app for being in college bro I myself am a few years out trying to learn swift while working and it's going about as smooth as when i tried to catch baseballs at the batting cages doggy style.

Beautiful and useful. I used it for my daily work, it helped a lot, but it still has room to improve. As in the time difference page, I inputed two time points, and the time difference shows as hours and minutes, can the time difference results shows in multiple formats such as all in hours, all in minutes, all in days, etc.

To figure out future dates it’s great!. I use this app all the time to figure out time periods. Like 90 days from today. Works great for real estate. You can figure out the number of business days between two dates. Also, converting months to minutes or any time period.

Nice app. The app works well, however it was not exactly what I was looking for. I was looking to display the elapsed time in years, month, days,hours and minutes from a date in the past to the current date and time, and store this event so that I can reference it when ever I open the app. Elapsed time since I started a project. All in all this is nice app that works well.

Very good. Simple to use and easy to understand and very handy keep the good work

Very useful. Extremely handy app for date / time calculations.

So useful!. I use this at work now instead of Excel calcs. Suggestion: have a search facility when choosing countries.

Nice done.. This app will be very useful. Thanks. Great idea and pretty well executed. The only criticism is the interface design, but otherwise it does what it says.

Simple and easy operation. Very nice and intuitive interface. Well done..

Cool App. This is a really cool app!... Only 32 days, 20 hours and 41 mins until I wake up on my birthday 😃

A worthwhile utility. Even better than described. Has many practical uses plus a lot of fun ones. (Today it has calculated that I'm exactly 73 years, 6-months & 9- days old :-) This app is one I'll use often.

Review. Great app tells me everything I need to know. It's worth the purchase too.

Wonderful app!. So good to have an app that offers so many useful options...

Great. The first usable time calculator that I have seen so far. It would be nice to see the different functions come together in some way rather than being all on separate screens.

Date and Time app review. Very handy app, use it daily.

Great app, but . . .. While I appreciate bring able to calculate the date difference and such like, I find it a little annoying that there is no ‘Enter’ or ‘Calculate’ Button to press once I have entered the required values. Just tapping somewhere on the screen is not an intuitive action.

Great app, very comprehensive. Does everything you would want. Highly recommend.

Comprehensive. This app does so many things I am unlikely to want to do that it covers everything I am ever likely to want. Simple interface. Well done - comprehensive

Awesome. Only got it today and have been on it for about 2 hours and best thing is I got it for free!!!!!!!!

Outstanding. Light, intuitive, easy to use and very very quick !

Excellent app. As a pilot I find this a really helpful app for doing time and distance calculations and as a person the other parts of the app are interesting and fun too. All in all a great little app, thanks mate I also just realised that I have this same gentleman’s percentages app which is also absolutely first rate and the only one I ever need to use, seriously well done mate, thank you!

Great App. Great app mate, would like to see improvement of flexibility with time difference eg convert two time into just seconds or hours and days or just weeks or maybe months and years. Cheers

Great little app. Works well and is excellent tool to have handy

Awesome useful app!!. I have used this app many times before and it has never failed to excite me. Very useful app. 👍👍👍

Makes fun calculating!. Time calculating is vexing at the best of...huh..times. This app is very good at kicking down the years into days or minutes or even seconds. Now you can calculate very acutely how much time you have wasted!

Excellent App. I love this app and use it frequently. Very well done

Amazing App. The best all-in-one difference calculating app I have found. Thank you

Fair App. Works quite well but would prefer English date setting rather than the American style. Also, countries and cities could be a better layout in Time Zones.

Love this app. Love this app keep up the good work. App works find for me no problems found as of now.

First Class App. It works well with no flaws and simplicity in the way it works. ⭐️⭐️⭐️⭐️⭐️

Straightforward & Simple. Easy to use, calculates everything you're ever likely to need calculated, well done!

Great handy app.. It'll save me from needing to use a website which I usually refer to.

I love this app!. This app takes all the guesswork out of time and date calculations.

Very good. Just downloaded this app 3 min ago and was bombarded twice to write a review, so here go and hopefully I wont be asked again. So far so good it really looks good and simple to use and does its job. Only thing I can see in the short time I used it is that I cannot change the date format. Where I live the day is before the month.

Handy Andy. Fun and addicting app that constantly delights with the information it calculates

A handy tool to use. Pretty helpful on time calculation, especially for someone working in a global org.

Pretty good app. I just started using it and I'm quite enjoying it. It's useful to know the number of work days and it does it very well. Well done!

Really cool app. Very easy and friendly with all the right scenarios

Fantastic!. This app is wonderful. Whenever my iPhone is running slow and I need to delete some photos or apps I make sure this one stays as it's very helpful :)

Love it. One of the best apps on my ipad! Being a teacher I use it regularly in class and in the staff room!

Great App. Excellent work. Would love to see a calculation for time difference across time zones.

Actually really good. This app is as it says 9 in 1 it does what it says with no adds. Surprisingly it's actually really good and is worth a download I throughly enjoyed what this app had to offer

Irregularly used but always appreciated. It does its time and date calculations well and doesn't try to do anything fancy or cute. When I need quick and simple time and date calculations this is the app I open.

Fun. Its easy and fun to use, although doesn't have the feature i was really looking for. I really wanted to have a count down feature that i could check randomly with out having to set each time.

Very handy app!. Very easy to use. Couldn't do without it.

Great App. Very handy for date & time calculations. Will be using this slot. Nice interface and easy to use.

So good I can scarcely believe it. Who'd have thought that calculating dates and times could be so much fun. Wow. One of the best apps on the AppStore. At least 5 stars out of 5, maybe more.

Very useful. This is a good app for making all sorts of time adjustments

Brilliant. This app helps me so much. It does exactly what it’s supposed to.

Love it. Well thought out and very handy, use it all the time working out rostered hours worked. Thanks

Very useful. A very handy app to have. Thank you. Works well.

Clever app, very useful. As a frequent business traveler this app will get a lot of use. Also I expect my kids to take advantage of it to.

The best so far,. I've tried a lot of similar apps and this has been the best so far.

Excellent!. Very original, useful and beautiful. Easy to understand and use. 5 stars well deserved.

Super helpful and reliable. Super helpful and reliable.

Pretty comprehensive. This app has all permutations and combinations of calculations required for either date, time, or combos thereof.

All in one. This app covers every time calculation you will ever need in one convenient app. Very easy to use. I use it for calculating when to reorder my prescriptions and also to calculate my movie schedules.

Amazing.. As a fellow programmer, graphic designer, and YouTuber, I have to say: it isn’t easy to make productivity apps with a very simple and beautiful layout. This man managed to do it. I don’t really have a purpose for most apps other than “Lists to do,” but I went ahead and purchased a package with four apps. No regrets, he deserves a lot more support and 5 stars. (Not sponsored lmao)

Good app. Great app for people interested in dates and timeframes in people's lives. Would be better if you could save the dates you enter without having to re-enter them each time you want to check things.

Impressive. Original, simple, working claculator

Not bad at all!. It is actually a really great app!

Does everything!. Well designed and useful.

Awesome!. A little confusing but great nonetheless!

Date & Time Calculator. Very useful in my business; Thanks

Good app.. Nice work !!. I'm glad I downloaded this app

Awesome. Fantastic little utility. So simple to use. Great job!

Easy to operate, great product. Recommended 👍

Fantastic. This is a fantastic app. One of the best I have on my iPhone.

Love it. Cool fun little app!!

Needs work. Cannot calculate time travel into miles or kms

Love it. Bastante útil!

Wow. Love this app! Perfect

Decent app for variety of uses.. As a construction project manager I use this app almost daily for quick checks on schedules etc, very handy.

Good app. Great to have

Date and time. Great

Great tool!. I've been looking for a long time for a tool like this one and it's working great.

Great app. This is a great app. Wonderful to have available during scheduling meetings.

Great!!!. 👌🏼👌🏼

Fast. Fast and simple to use. Needs commas in final answer display for easier viewing ( as in 32675000.25 easier to view as 32,675,000.25 etc ).

.. Fantastic

Saves me a lot of time. I love it!

So far so good. It would be cool to have comparisons to all your children and grandchildren ages to see how old you'll be as to yor estate planning. And to consider your few remaining days to love each other well.

Date & Time Calculator. Simple, solid functionality.

Very good...but. I'm a little disappointed that I can't convert years to Star Trek star dates.

Good. Good

Very Handy. The app does what it's supposed to do with aplomb.

Great!. Awesome app

Great. Super fun and handy!

Pretty good.. Easy interface with lots of interesting variations on working with time.

Well thought out. More than 40 years ago I had a Casio "Time Comp" calculator that was a great source of enjoyment. This is a worthy successor because it does everything that device did and so much more.

Date & time calculator. It is a very good useful tool. Easy to use.

Accurate. Love this app for quick and easy date calculations! I use it all the time.

Great App!. This is a grear app, very precise, very well done. Congratulations to the person who designed it and developed it!

Review. Great app! It takes the math out of figuring out time, ages, distance etc. Very useful.

Amazingly helpful app!. I love this app. Find new uses for it every time I open it.

Fun app. Love this app, very useful and fun! Works well.

Fantastic. One of the purest apps I've seen. Get it, you need it. I have it and will probably use it today I learned my last breath. How's that?

Great App. It is a great app have used it on a regular basis

Very useful app!. Easy to use

Great app. This app is used daily in our business...great asset.

Date and time calculator. Very helpful tool, I like it very much

So user friendly. I use it all the time for work.. Stop looking. Get this app.

Excellent App!!!. Does everything you'd want a date-time calculator/converter to do...Easy to use...simple and straightforward. Excellent!!!

Great app. I love the app. Has everything you need and very easy to use. Must have

Essential. This app is just great at what it does. I can never figure out how much time is between two dates, but I need to know this information pretty often. This app does it wonderfully. It's one of a few apps that I would never be without

Needs Weeks and Months. When trying to find the amount of time between two dates, it would be really helpful to get a week and/or month view instead of getting told 244 days. Otherwise, clean looking app.

Essential App. Does every date calculation I could possibly want and then some. Simple interface beautifully executed. Worth every penny. Perhaps in a future addition you could add a countdown timer to a future date.

Great app. I work in the legal professional who uses the date calculation quite often to determine court dates and other pertinent information. I have found this app is very helpful and converting various types of information

Fantastic!. I have downloaded many time and date calculators because I enjoy figuring things out with time. None of them have been as comprehensive as this one. Most can calculate days between dates, etc. but this app even has things I hadn't thought of to calculate. It is a great app.

Cheap at Twice the Price!. I had found solutions for my time calculation needs but to get everything I wanted required me to obtain six apps. I already had 200+ apps so I didn't want six more... but then I found this one! Solved all of my problems in ONE app. I'm delighted!

Pretty Spiffy, Alright. A really good time calculator. I work in broadcasting, and have long sought a calculator of this caliber. It's practically a five-star app; I'd like to see copy and paste functionality, maybe a little better way of setting locations in the world time comparison, and a numeric keypad come up instead of just a keyboard that requires switching with some entries.

Best that I have ever used…. I have purchased and used several time calculating applications for my iPhone… This is by far the most complete and the most accurate time calculator that I have used… Highly recommended…!!!

What a great app!!. I use this app on a daily basis during my day job and it is more than handy! My only suggestion would be to add a "done" button to the keyboard to better trigger the result once the data is entered. Overall I give this a 5!

Super Helpful. Light weight APP that's really helpful when you need to count days to dates and other math related to time and dates. I even use it to calculate deadlines for canceling reservations (I.e. 45 days before) or to calculate when bookings are open.

Excellent app!!!. I sometime am on the clock for a few days straight which makes it really hard to figure my hours and minutes, this app makes it 10 times easier 👍👏

Dates More Accurate Than Microsoft. This app does all the standard date calculations and it does them correctly. It even knows something that Excel doesn't know: 1900 was not a leap year. The interface could use a little tweaking to be a tiny bit more intuitive but having the right answer is priceless.

Ingenious problem-solver. Easy to use. As a doctor I often need to calculate the number of days between two dates when I write prescriptions for travel. I no longer have to grab a wall calendar and count off weeks by hand!

Just what I needed, except for one function. I love this app. It's easy to use and have many functions. I love it. However, I have one suggestion: I would love to have a birthday calculator that is in weeks old only. I need this function for work often. Thank you!!

Exactly what I wanted. I simply wanted to know what the date 22 days in the future would be without having to count the days on a calendar. Added bonus; I could go directly to my Fantastical calendar and mark that day.

Good Stuff. In my work I need to do a lot of basic time calculations. Rather than count days on a calendar I was using a spreadsheet. This useful app makes it quick and easy on the phone. Thanks!

No more searching internet for date calculator. No more searching the internet to calculate dates and times. It’s worth it just to have date calculator. use it frequently as an attorney.

Very useful. I frequently have to set deadlines for projects several months out, and until I used this app, it took several minutes to determine the exact date for a suspense of 3, 4, 5 or 6 months. But now, it takes only a few seconds! Great app!

Good Functionality. This app is useful to me for quick and accurate calculations, It provides a wide selection of date math functions. I use frequently. Easier than building spreadsheet formulas. Developer is responsive to feedback.

Very handy. Its very easy to use. Saves me tons of time doing my hours of service at work. The only downside is the developer having the pop up constantly asking me to write a quick review on it. I usually dont have the time so i ignore it. I recommend you do it immediately. Afterwards here is nothing bad i can say about it

Useful App. This is a pretty good app. My only complaint is the seemingly random - and not very intuitive - choice of example cities in some of the time zones. One would expect to find large and/or significant example cities (e.g. Chicago, New York, London, Moscow, etc.). But I found some teeny tiny example cities, like Shiprock, NM, population 8,156 - while much larger cities I expected to see were absent.

Best date/time calculator out there. I've tried them all, even bought a couple but none of them ever did everything I wanted. Now with this app, I was able to delete them all and just use this. Very nice app.

Great App. Multi functional, converts to military time, time in another country, and age other features I have yet to explore. The cities in countries could be improved but over all useful. ie United States instead of America

Great App. Very happy so far with the app and it provides the need that I had for getting it in the first place; that of a calculator to give me the number of days between two dates. Meets the need. Keep up the good work. I think the interface is a little simple, but I'm sure that improves over time.

Registered Nurse. This app has made my clinical day a thousand times easier and faster... I work in pain management and have to calculate pump refill dates as well as med refill dates... this makes determining those dates so much quicker! Thank you!

Really useful app. I originally bought this app to help plan personnel actions while I was working. It was a great help in making sure no deadlines were missed. . Now that I'm retired, I'm still using it to make sure I don't miss deadlines, but it's more fun when I have to prove a point!!

First class app!. I have used this app often, most recently to figure how many years after two Wright brothers made the first fixed wing flight until a man first stepped on the moon. 66 years if you're interested! Thanks for creating this wonderful tool!

A Wonderful App. A great app that helps me specially with work hours in a flash. There are excellent options for time calculations which I find myself referring to their use more often that I would think. Thanks for designing this useful app. I highly recommend it.

Great App!. I work in the construction industry and daily need to calculate dates and how it equates to working days. The way this app not only identifies working days and dates but also identifies Saturday’s for potential production days has helped us tremendously. 5 stars!

My "Go To" App for time calculations. This app has a lot of time calculators. My fave best is the one that lets me calculate how many days to an event. It's flexible and intuitive to use. You can even multiply time by 2. And time zones are now organized by continents and then by major cities e.g. America/New_York.

Very good. Nice, but I'd like some improvements. An enter button for when your done with the keypad entry to finish the calculation. Not having one is awkward. The calculation should remain and not switch back to the default example when switching between calculators or the closing app.

Needs search functionality. It's a great concept, but when finding time in other time zone, there is no search function to find the location, scroll bar, groupings... So you have to scroll through hundreds of locations that is grouped in "zones". It needs to group them so you can jump to zones that may contain your city, or search function, etc...

Great time calcs. These app taken I many different of those pesky time calculations and makes them simple. It is nice to see how many working days until you can retire - just DONT get depressed when you see the big number.

Very Useful!. I’m a pilot for a large international freight company and travel around the world every month. This app has become an indispensable tool to me for easily and accurately calculating flight times, rest periods, and layovers. It’s extremely useful and easy to use!

Absolutely Fantastic!!. No other app like it! And this was done by a college student!?! VERY impressive! Clearly they are on the Deans list! I recommend this app to everyone, because it is useful for everyone in some way. I cannot compliment this app enough! Way cool! 6 stars!!

Great. Just needs a Roman Numeral Converter. Really good, with so many features to love. I can only think of adding a feature to deal with dates in Roman numerals, which so often show up on buildings and on the title pages of old books. Everything else you could want is already here.

Works Perfectly!. This app is extremely useful whenever you need to calculate anything with dates or times (go figure, right?). I have used it for several months now and it has come in useful in many different situations.

Perfect app. Just what I was looking for. Only thing that would help me out would be if you could get the total time between two point. Not in days hours min, just in hours and mins. Thanks for developing this great app. Wayne

Easy to use. It’s fast and easy to use. I travel a lot so I have to see date ranges for ticket validity and stay allowances in some countries. This app makes easy for me to determine the days or months from start of travel to end.

Works great, easy interface. Time zones and time differences can be hard to understand and I've used some apps that can be bewildering. This is easy to use and has a huge variety of handy calculations regarding time.

Exceptional Tool. I can't begin to describe the number of times I needed to be able to know a future date & had to count, most always being off by one or two days. This program is extremely easy to use.

Very good app, lots of application. First off, this is a very good app because you can actually use it, hasn't crashed yet like so many other apps and it's very easy to use. I haven't used this enough to actually provide a thorough review but from what I've been able to do with it, here is an idea: 1. Time conversion- perhaps you could add time zones or country so you can actually figure out if it's 8am now in say the US, it will figure out what time (and day) it is in Australia. Ps: I wouldn't mind paying for this kind of app as long as it's actually usable and being improved over time so, way to go!

Makes Conversions a Snap. This app is easy to use and makes these calculations much easier to have right when you need them. The possibility of saving conversions would be really useful. A power app would include conversion of many varieties in the same easy-to-enter format. Great app. Great Potential

Really Useful. Originally downloaded hoping to find a quick way to determine time/days/years between dates, but I am VERY pleased to find that this app has more uses than I'd hoped! Extremely pleased. Great app - keep up the good work! Love it! 😀

Awesome, easy to use, easy to understand. Great app that is easy to use and understand. It does exactly what you need it to. The user interface is simple and allows you to quickly get the data you need.

Good Program.. I really like this program. The only thing that I think is missing is the ability to add weeks to the calculations since there are some things counted in weeks.

Very useful tool to calculate time. I love it. It is very usefully specially went you are in a hurry and don't need to brake your head to calculate how many hours at work or home.. If needs some order in the time zones, but overall is a good tool.

Love this app!. This app is perfect for quick calculations. I use it to quickly figure out a date 90 days or 6 months out. So easy to get a quick answer (instead of having to open excel or look at a calendar). Love this app!

Great App. I've searched long and hard for a way to do multiple time calculations and could never find any app/website that did all that I wanted. This app has never failed to provide answers for me and I think it does it in an efficient and sleek way!

Not as intuitive as I would like. I am always needing to figure time between 2 dates. This app seems to be able to do it. I have only had a chance to use this app a couple of times before being asked to write a review. I find it annoying to be bugged to review so soon after downloading.
