CRON-O-Meter Reviews



Cronometer is the best app I have period. I recently decided to start a Keto Diet for health reasons and was looking for an app that would best allow me to track my consumption and meet goals. I did try various other apps before I found Cronometer. Now I find that I love Cronometer and will use this app for life no matter what diet style I use. If you are looking to manage your health Cronometer slays the competition!


not what I was looking for  Dramma10  2 star

It was too hard to use, and not at all what I thought it was going to be.I wanted something simple to replace Myfitness Pal. I wanted to change from myfitness pal, because I wanted to keep track of net carbs In googling macros, I found a sight that recommended this. As I said it was hard to use. It was not what I was looking for. I bought it and then deleted it right away

The best  Steen a Dane  5 star

I have tried most of the nutrition apps in the App Store. This one is very easy to use and has much more reliable information. If you only care about calories I guess any app will do, if you care about nutrition this is the one to use.


Needs better recipe integration  sberberich  3 star

I would use this app more if it were easier to input my custom recipes. I only eat what I cook, so I am constantly needing to add new recipes. Other apps make this easy by using a “bulk add” option for ingredients. Cronometer asks you to input each ingredient separately. The “Add Recipe” interface isn’t intuitive at all and I’m not sure I’m actually using it correctly. It would be nice to have better options to categorize the recipes. “Meals, Dinners, and Sides” isn't a useful tag. I’m not sure there’s even a way to pull up recipes by tags. Overall, I’m still on the fence with Cronometer.


Best Food Journal  Happytraveler099  5 star

I have been using this ap since 10/1/18 and I love it. Over the years I have tried food journaling using various methods; notebook, weight watchers, nutrisystem, Atkins app etc etc. I had never found a method that I could stick with for more than a few days. With Cronometer entering the data is fast and easy. My activity data from my fitness tracker syncs automatically. But the best part is the useful info the ap provides; how many more calories I need to burn in a day, how many more calories I can eat, as well as nutritional information. I am continuing to learn more about the copy and paste functionality. For me, it’s powerful motivation to see the calories of a food choice in my overall meal plan and look for ways to make better substitutions. I am using the Gold membership and feel it’s well worth the price.


Love the full Apple Health Integration  phtully  5 star

Much better than MyFitnessPal

Great for Keto  Taylor Hively  5 star

I tried many of the other food tracking apps but most of them don’t really work low carb as they don’t count “net carbs” toward your goal. This one allows you to customize carb, protein, and fat goals (if you don’t want the suggested ones.) I find this easy to use and pretty accurate. Also it syncs activity calories from the health app (apple watch activity.) My only tip is set BMR calories in the app manually to your average “resting calories” in the health app as Chronometer doesn’t read it. That way your total daily calories will almost match the health app

Decent but other app offers what gold does for free


40g carbs for keto?? Um, no  whocaresjustrateit  1 star

This app freezes up constantly. That, and I’m trying to do keto but even though I put my settings as moderate keto, it says I should eat 40.0 g of carbs! That’s not keto. Also, I entered that I ate two cookies (just to play with the app), and it says I have eaten 2.1 g of carbs. That’s a nope: it would’ve been 19. Waste of $2.99 and time.


Awesome  bnnna44  5 star

Cronometer is an awesome service that provides the most detailed dietary information, hands down. Been a happy user for nearly 5 years and will always recommend.


Newest update is great  Byron85  4 star

Great app it has assisted me in loosing a lot of weight with intermittent fasting and quick. Support with staff has also been great. It’s nutrition info and health kit intergration is the best out there. The only negatives: -they are yet to implement the Australian barcodes on a mass scale but they say it’s in the works. So scan the food at the supermarket if your worried it isn’t in there yet. - fasting timer would be handy - some sugars are counted on products like quest bars which humans can’t motabalise so it should really be zero.


Not for Aussies  OzMuso  1 star

Useless in Australia. So disappointed.


Great nutrition app  Supergem10  4 star

Easy to use, love that I can see my vitamin and mineral intake as well as protein,carb and fat %. Has most foods you need, just doesn't have many packaged Australian foods, but you can always put them in yourself.

I was an addict

Not good for Australia!!  I was an addict  1 star

I want my money back honestly!! This app doesn’t have much selection of Australian food! 😤 big thumbs down from me and a big waste of money!!


Not great for Australian users  Belpal  3 star

Has a great nutritional breakdown but not many Australian products recognised. Would be good to be able to add breakfast, lunch, dinner & snacks seperate as easier to keep track of entry.


Love this app, but have some suggestions!!  Bekaaxo  4 star

I love this app, it's so useful!! However i wish there was more data for Australian users in terms of food and barcoding (as many people have mentioned below) also I wish there was an option to add how many cups of water you've had in a day, to track water intake. And lastly I wish there was a way to categorise the foods you eat into breakfast lunch and dinner categories to make it look neater!


Great layout but needs Australian data  ellelaia  4 star

The app is fantastic but it is very difficult to use properly when there is no way to input or scan Australian foods. I'm more inclined to use MyNetDiary because it is easier to use.


Love ur app and have suggestions  Sharazz  5 star

I love you app but in Australia it is frustrating to use. Can you please allow us to scan in items and then photo the contents for you to add to your list of items and then your R.E.M. can review photos and add it to the core list of products. This will help to improve your use ability in Australia. Also we call peppers, capsicums. If you cannot do this can you at least allow us to scan barcodes into our own food diary items and recipes so that we can just scan the barcode for future easy use. It is so frustrating to have a barcode system there but you are not using its potential in Australia. Surely you can use this feature to maximise your database without having to leave your chair by using photos emailed to your team of products. We customers can be doing you a favour! Thanks so much


Won't let me log in!  AdeleAwesome  1 star

Won't let me log in to my old account, or make a new account, or use Facebook or Google to log in. I've paid a fair amount of money for this app, please fix this! The app is completely unusable


Macro Magic  andorado  4 star

A well designed, easy to use app for tracking macros & micronutrients. Its only fault is the out dated concept of weight loss dependence on calorie deprivation. It needs to be redesigned to allow for the new carbohydrate driven weight gain science.


The best out there  HonestJoeA  5 star

I think this is the best app for a keeping track of your nutrition. I absolutely recommend this to everyone. Also, thanks for updating the screen :).


A-ma-zing!!  Shwalt  5 star

Absolutely love this app. So clever & smart & discovering so much about it to love: 1. You can choose what sort of diet mode you want your macros to be based off. I chose "keto" with moderate strictness. It ADAPTS your daily macros to your calories burned! (Wha?? I always thought keto was a "One size fits all low-carb program"....turns out: no!)<--- favorite thing about the app 2. You get a snapshot of where you are within your vitamin & mineral goals. 3. You get food recommendations to help you meet those goals! 4. Back & forth sharing with other apps (I chose this with my Fitbit- only need enter food data in one spot ). 5. Reliable nutrition data....finally...YES & thank you!!! I can't say enough good things about this app. Love, love, love!


Needs more features  Nooniogoolir  4 star

This is a great app but needs more features including: - multiple users for families. (They expect each family member to have their own account, including kids) - better Australian features - add recurring daily foods & exercise - All in all, I love using it. Just needs more.

Oogabooga! Jeklin

Great except for one little thing that drives me batty  Oogabooga! Jeklin  4 star

Every day I use this, I look through all the trackers and it ALWAYS says that I've consumed trans fats that day. Every single day. Which I know is not correct because trans fats are banned in my state. What stinks is I'm not sure what the developers could even do to fix this problem. If there is something that can be done about this it would be really helpful. Usually its just a matter of scanning the product instead of typing in "cheese" or something like into the food search, but sometimes it doesn't recognize the barcode, and you HAVE to search for something like "cheese" or "beef" and I swear unless its a fruit or vegetable it always says there's trans fats in it. Not every food has trans fat in it.


Log-in issues  Nbastyle2121!  3 star

I’d give the app itself 4 stars. I downloaded both the free version and ad-free version. At first the free version worked fine. When I downloaded the ad-free version it made me log-in with my Facebook account every time I opened the app. Now I am unable to log onto neither app using my Facebook account.


Well Designed App  chriszumberge  5 star

Unlike most other apps of its kind, Cronometer also tracks vitamin and nutrient consumption. The ability to scan barcodes on food products and the simplicity with which you can add custom recipes makes the application easy to integrate into your daily lifestyle. Another key feature Cronometer offers is integration with Apple Watch and Health Kit to accurately track burned calories throughout the day.


Best app for Keto diet  ryan1973  5 star

I’ve used them all and this is the best. If you like a lot of control, detail, and accuracy, this is the app for you. I found the other apps to be inaccurate when it came to nutrition information. It takes a few minutes to set up, but the tutorial videos and online user information are easy to understand.


Awesome app, thanks!  philwinkel  5 star

Thanks for fixing it on iPhone X!


Best option to track macro's on Keto  Airrick2009  4 star

This is the best option to track your macro nutrients if you're on the ketogenic diet. Net carbs are recorded and you can easily set gram limits and then just spend your day working up to your macro goals. I'm giving it 4 stars because it lacks some features I'd like to see that are in other apps such as separating meals into breakfast, lunch, dinner or iPhone X support. Better sharing with friends options would be nice so you can compete with each other. All in all I recommend it.


Best of its kind  Talkingmountain  5 star

I’ve tried all the major food diary apps out there and for tracking calories & nutrient intake, none is as good as cronometer. Their database of foods is the most comprehensive and most importantly, its accurate. It’s easy to add foods not in the database, but before user-added foods are shared with other users, a Cronometer staffer reviews them for accuracy. So you don’t run into the problems of inaccurate user-submitted data that most of the other similar apps have It’s easy to create a custom “food” for combos you frequently eat (e.g. favorite coffee+creamer+sugar). It’s easy to track foods using word searches or barcodes. It’s easy to track anywhere (web app, phone, & tablet apps all sync). You can customize your calorie & nutrient goals (even water intake) as much as you want or let them calculate them for you based on government guidelines. The graphing options are simple and powerful. With their graphs, my nutritionist and I discovered several unhealthful patterns that we were then able to address. It’s free and the ads are not intrusive. Customer support thru the new Online (and free) the user forum is great.


Dissapointed  Trev198383  2 star

Overall seems an okay app but dont bother downloading if your live in UK & Ireland as doesnt recognise products. Seems more geared towards US & Australian market


Don't waste your money stick to the website  Elliot1713  1 star

Countless bugs, won't let me edit my target calories no save button, can't go backwards if I change a page the button just goes unresponsive. Badly designed website is much better


Don't waste your money !!!  Catface12  1 star

Badly designed, can't see any explained breakdown of your input. Just stick with the free pc version, much easier to use. I have been using that for a long time now. Sorry and annoyed I wasted my money on the app. It's just a gimmick to rip you off !!!
