Great Experience. This is a great app and I've have a great experience thus far. Thanks for creating this, you have saved me a ton of time!

Great App.. Highly recommended.

Great App. Simple. Easy to use. Just what I was looking for.

Easy to use and very useful.. The interface is simple and easy to use. Overall, it’s a very handy tool for those times when you need to calculate dates and times and want to be sure you’re getting the correct answer.

Great app. We are traveling full time in our 5th wheel trailer. This application is very helpful with planning and setting up reservations. Some places only accept reservations 90 days in advance and 120 days in some others. Oregon state parks 9 months. It’s true sometimes you can find a place that is only first come first serve.

Good app!. Works as promised.

Nice app!!. Very user friendly, good graphics, easy to understand, use it a lot with upcoming events

Great app. Love using this app Easy to use, very helpful Use all the time

Best BiPac Machine on the market. I’ve been using this machine for many years & has changed my sleep remarkably 🛌

Awesome. Works awesome

Great time/date app!. One of the best time/date app out there. Would be perfect if there was a divide option in time calculator as I’m having to use a separate app for that feature alone.

Very easy to use. Strongly recommended if you need a tool to calculate the timelime or provide the exact date with a start or end date with a duration.

Great App !. Use it often, just what I needed! Recommend,

Excellent tool!. Thank you very much!

The Best App For.... I am a 34 year old man living with Crohn's Disease. Unfortunately, the doctors have me on a lot of medicine. I needed an app so I know how many days I have until I have to have my medicines filled. I have tried a lot of the free apps that the App Store has to offer but a lot of them were too confusing. Very rarely do I spend any money on an app, but I went with my gut 😀 and bought the date time app. I LOVE this app. It is perfect for my needs and is very precise when making calculations. It will give you from, when, days, hours, minutes, seconds and so on. It even lets you put in dates from years ago! I even know how old I am to the tee when calculating the day that I was born until the present and it gives me everything and anything that I could possibly want to know. Whoever designed this app is extremely intelligent and has their head on right. Neat and fun app. I use it on a daily basis. It's especially useful when calculating the day when I have to call the pharmacy for a refill. The only thing I wish this app would do is to make a sound of when 15 days or 30 days, days of importance are vital. Other than that, perfect app!

Hospital Quality. I use this app almost daily. Would have given 5 stars if military time was included.

great way to find time from date to date. it's great instead of counting calendar dates now it's @ the tip of your fingers

Was WAY better before. In updating the program, they seem to have done away with the ability to calculate weeks, days & months. I paid for the app, thinking the paid version would have that flexibility — it does NOT. DEVELOPERS should bring that functionality back!!!

Highly recommended.. I don’t often give reviews, normally I would just give it a star rating but not commenting. I recommend this app. on time management along with multiple options you can do. For example: Instead of going to websites, with this app you can add or subtract 40 days or 40 weeks. The rest is your choice.

Works very well. Great app! Helps me resolve date counting. Very detailed.

Keeps its promise. Does what it promises without a fuss, use it weekly.

Does exactly what I need, no fuss. My work has me calculating time every day all day. I would do it by hand, but there can be no option for errors. I paid for the app to get rid of the ads. I open the app, go right to the time calculator and I have my answer in seconds.

Why. I paid for the app to have no adds and I am still having ads

I tried them all. I tried a bunch of time and date calculators and used them all and I kept coming back to this one. It has everything I need and it is very simple.

If it could only. If it could only switch to landscape, d'd give it a s-star rating. Very nice app otherwise.

Easy calc, can’t copy results. I like the app, although I don’t like that date selection uses a scroll wheel. It would be faster if I could just enter the date using the keypad. I do mot like that you can’t coly or share any of the results. None of the fields allow you to copy the results of your calculation. That’s really frustrating not to have the ability to copy.

Excellent App. Well worth the price... accurate and no problems!

Great app. Works great for planning and scheduling

Missing important setting. Your Date Time tab in the app is missing an adjustment wheel for setting a year. That is a huge oversight!

Best app of its type. Simply best and very useful.

Works well. Easy to use.

Exceedingly helpful app!. As per the title, this app is one of my favorites. While I may not use it as frequently as other apps since it has a very specific utilitarian purpose, it has a prominent space on my home screen (first page) because when I do need to to calculate some date or time difference, this app is invaluable. As far as I’m aware, it’s able to do all the calculations relating to time and date that you’d need. I also appreciate that it has buttons to “clear” some text boxes so you don’t have to backspace-backspace-backspace and just get rid of your previous input with one press of a button. I also appreciate that for some text boxes, there is a button for “today” that inserts today’s date so you don’t have to do the whole scroll for the month, day, and year just to get today’s date. All in all, this is an A+ app that I’d very much recommend!

Time Saver. I use this on a regular basis to find the (hours and minutes) between medical surgical events, and it has been accurate with no crashes so far. I've been using it for months. It is easy to enter dates, hours, minutes, etc. and the options are covered well.

Best. This is the best date calculator I have found.

Great app. Well worth a buck.. Great app for calculating the difference between dates.

So happy I found this app!. It's not super intuitive but once you grok it being able to quickly calculate and manipulate dates and times is a real benefit!

Can’t reinstall my purchased app. Hello - I had to reinstall my phone after it crashed. Even tho I paid for this app, it is unwilling to restore my purchase. I didn’t want to post this issue here but cannot find the developer’s contact info w/o going thru Facebook & I don’t have a FB acct. Mr./Ms. Zhang, can you help? I love this app & will replace this review & star ratings after this issue has been resolved. Thank you.

Use all the time. Works well and very useful

Advertisement. Advertisement in paid App, this is incorrigible!

Time saver. Use this app almost on a daily basis due to work moreover, I have found it very helpful.

Useful. I use it for future/ Daily planning. It’s s super simple and I suggest implementing it into your daily planner or whatever works best for you.

The BEST 🙌🏿🙌🏿. I rely on this app whenever I need to quickly calculate dates and time. It’s easy, quick and doesn’t take much effort or time to do anything. LOVE THIS APP 🙌🏿🙌🏿

Private Data Not Collected. Five stars for respecting everyone’s privacy and not collecting any data. This is very rare and needs to be applauded.

Nice App. Very user friendly!

Top Notch Utility. This has turned out to be one of my most used utility apps next to checking the weather! It is simple in design and very useful. So much of what we do evolves around dates, times, and scheduling. This is the very best tool that can do it all in one app!

Great job. Most definitely worth a dollar to support this developer. Simple, but very useful little app. Nice interface.

Junky app, do not buy!. Junky app, navigational boobytraps, do not bother with free version, do not buy!

AWESOME APP. Does exactly what I need it to do!.. easy to use‼️👍🏼🤙🏽

To date keeps changing. I

A tool, a toy, a necessity for recovering OCDs!. I use my “DateTime” all the time, sometimes just to determine a fun fact, but often as a valuable time, date and valuable deltas that I need! Kudos Shan Zhong for a very cool app! No change! STILL a great tool

WRONG!!!. Gives a WRONG result when calculating years. For example, when calculating the time difference between 11th May 2012 to 23rd November 2014, the result shows 2 years. WRONG! The answer should be 2.5 years.

An App you’ll Reach for Often! Home Screen Worthy. Personally as a mathematician, software engineer who graduated in 1994; I find that the power of great calculation & visualisation apps far better than the old grid lines & pencil! PROF. USE CASES: Accountants, Journalists, Researchers, Scientists, Doctors, Engineers, Project Mgrs, Teachers, Students(!!), and the list goes on. PERS. USE CASES: Anyone that lives a modern day and hectic life- great for family scheduling and budgeting (!) This app is front line in my range of PERSONAL & PROFESSIONAL calculation apps these days. The lite version is great, but for skipping JUST 1 latte from your favourite store, consider supporting developers & software engineering professionals (such as myself) with an app I guarantee you will reach for many times. It’s truly worth helping the “indie devs” or as in Microsoft terms,(well is was back in 2000 😎, “ISV” - Independent Software Developers. Now TEAM, there could be some improvements in the UI display & feedback - happy to chat (as a consultant) to the UX/UI people about contemporary design of math-app design.

Good App. I'm a project manager this apps great for doing quick scheduling calculation. An ability to not count weekends and public holidays would make it perfect and a good reason to update to the professional version.

Need to add YEAR roller to DATE tab. Other than that a pretty good app

Thumbs up. This is a really great app. I've been looking for a simple way to keep track of my work hours and this app is better for calculating daily shift hours than any app I have come across previously. I regularly work night shifts and most time calculator apps have difficulty calculating the pm to am roster, but this one makes it extremely simple. Thank you, I'm glad I found you

Does the job. This helps me to track when my current pack of medications will run out, so I know when I need to buy more. Before this I really struggled to buy them in time before they ran out, do this works really well!

Big doubt with this app …. Be very careful! Just after installing this Chinese app, all my cryptomoney was stolen in my Trust hot wallet. Fortunately, there was not too much but this has been immediately uninstalled.

Great little tool. Easy way to keep track of my vaccinations, medical test etc.

这个软件太方便了. 尤其是对做project而言，对需要快速估算到期时间特别有帮助

PrairiePilot. A lot of work has been put in creating this piece of software. I really appreciate this one

Excellent. Sorry for misleading earlier review citing lack of added time from specified date. App Works great.

In order to advertise on the site in Adsterra, like other ad networks, a certain traffic limit, domain age, etc. is required. There are no strict rules. Sign up!

Very useful app. Great for date calculation

Easy to use with great interface. So simple yet gives you a lot of info. Just swipe between two scrolling date selectors and the difference is calculated. A snap!

Time. It don't have am or pm and why dose it show only military time wast of 99cents

good app. pretty good

Timing. I would be able to use this app if it would accommodate military time but it doesn't

Great. Works as Advertised.

Keeps good track. Easy to use. Accurate.

Date calculator. Use it daily and love it !!

Does exactly what I want it to do.... ...intuitive interface. Provides my day calculations. Simply stated; it works!

Great App. This app is wonderful! I use it a lot. I do wish that under the "Date" category that there was a Year, Month, Day combo. Or if we could change the ending parameters to our liking, other than that I have no real issues with the app. Best one out there.

Works fine. Easy to use. Agree with another reviewer that adding military time option would be nice - good idea for next upgrade.

Daylight savings time. There seems to be a discrepancy between daylight savings time for calculation.

Timemaster. Love it, does exactly what I want.

Emmanuel. I like it!

Good App！. so good

Easy to use. Well thought out design. I use all day long as a physical therapist. Wish you made this for android

Calculates # of months correctly.. Other apps don't calculate # of months at all or inaccurately calculate # of months based on # days in a month always = 30. This app correctly calculates # of months based on the # of days for the included month(s). For example 29 days in February 2016 and 28 days in February 2015 = 1 month. Good job.

App review. Great App!!!!!

Pro expirations. I just bought pro version on Nov 21 2019 .. Don’t I get for one year at least.. why does it says will expire after 6 months 5/20/2020.. And also it didn’t specified pro was for how long (6 months, year or forever).. little misleading there. But I like this app and probably use it depending on.. don’t know yet full quality..
