Who it's for
Cronometer is for users who prioritize detailed micronutrient tracking and appreciate a robust free version with a barcode scanner R68R59. It is suitable for those serious about diet and nutrition, including specific needs like breastfeeding . It is NOT for users seeking a simple calorie counter R15, those easily frustrated by frequent ads and bugs R32R153, or those who rely heavily on a vast database of international or raw food items R305.
Evidence note: The recent reviews skew heavily towards negative experiences, particularly regarding ads, bugs, and UI changes. While the lifetime rating is very high, the recent sentiment indicates a significant decline in user satisfaction due to these issues. Evidence for core positive features like micronutrient tracking and the barcode scanner is strong and consistent across reviews, but recent issues are impacting even these core strengths.

What reviewers actually said
Built only from these 120 real reviews (foreign ones translated). Superscripts jump to the quote here. Apple has no per-review links, so [ref] opens that app's reviews on the App Store.
- [R5] Best health app out there: I love being able to see how I’m doing with my nutrition goals, even down to specific minerals and vitamins.
- [R6] All the biometrics: You can monitor all your biometrics. Everything. And if you have the paid version you can get suggestions on the nutrients you may need. Finally. A good app and at a decent price.
- [R68] THIS APP IS THE 🐐: I’ve used this app for ~6 years with varied consistency, different goals, diets, and hrt. It’s probably the MOST comprehensive and customizable FREE fitness+nutrition tracker. What initially stood out to me was micronutrient tracking which idk any free app that does (or even paid!). But it’s so so important. I feel FANTASTIC when I’m hitting at least 40/50% RDI on micros. I wo
- [R54] Great for micronutrients and photo recognition: I’ve tried a lot of other apps, and this one is excellent for tracking micronutrients and supplements. The AI photo analysis works surprisingly well, especially for estimating portion sizes. I also really appreciate that there’s a web version, and I use it regularly. I just wish the web app also supported photo uploads. The UX can feel a bit clunky
- [R1] Best free cal tracker that also has free scanner: It has a free barcode scanner basically everything you need and can create quick profiles for unknown food items for free with your cammera
- [R51] Love it!: I absolutely love this app! I used to use Myfitnesspal but I find this one to be far superior. I love being able to scan the barcode so there is no searching for the food. It is exactly what I am eating. I haven’t found a barcode the app didn’t recognize. It is easy to understand. I highly recommend it!
- [R55] Fantastic app: Easy to use, intuitive UI. Free barcode scanning makes data entry frictionless. Highly recommended.
- [R62] So easy!!: Finally committed to tracking my Marcos using an app rather than eye balling it and this app has made it beyond easy!! The bar code scanner is a cheat code forsure and it’s relatively easy to build and create new meals if you are meal prepping.
- [R4] Easy to use: Cronometer is easy to use and provides a wealth of information. It keeps me on track with my nutritional needs.
- [R17] Daily Necessity: Loving this app so far. Been focusing on my workouts and staying more active and building strength but always neglected any kind of food tracking. Decided to start taking that more seriously and this has been an absolute asset in that part of my journey. It really helps you see the impact of what you eat and helps you better understand what you’re putting in your body and how it t
- [R31] Great app: This is one of the most useful apps for your health. I lost 60 lbs in part because I got serious about tracking my nutrition and this app was indispensable for that.
- [R58] Love this App❤️: The features are incredible! It is very easy to use. The information I gain about my nutrition is very valuable. Thank you!
- [R39] BEST APP: this is the best calorie tracking app and they don’t completely deprive you of features if you don’t pay premium unlike fitness pal and other apps !!!!
- [R40] great app all together: this app is really great , it has a lot of foods and the scanning barcode feature is really nice, obviously its a little annoying that theres features you have to pay for, but i love that the app is still completely functional without the bought things.
- [R53] Great app for both free and paid features: I used to use MyFitnessPal for a while until they locked a lot of their free, previously useable features behind a paywall. I found this app after some research and have been using it ever since. It has great free features and the subscription has great features as well, especially if you want to help support the app. You can design which macros you want
- [R59] Very decent: Hi sorry I'm writing this super late so I'm not sure it will be readble but: I downloaded this app expecting to have to pay for all the good stuff and I didn't! It's very much free and they make it so easy to track protein and fiber and hit all your goals. I have not one complaint for this app it works the way it's supposed to and I respect it. Goodnight
- [R12] Love it!: I like that if I take a photo it tries really hard to identify all the elements of the food. Really handy for hamburgers or tacos ha. I lost 20lbs and 5% body fat over the space of 3months and now feel better than I ever have before. Really happy with this app!
- [R24] Too many ads and pop ups: I used to love this app but the ads and pop ups are out of control
- [R32] Ruined by Ads: I switched to this app a long time ago when MFP ran ads and I enjoyed the run. Started using it again recently and every time I feel productive about adding my foods, it shows an ad and KILLS my productivity.
- [R119] Ads malfunctioning: I’ve really loved this app. Been using it down over 100lbs. The app itself is great but lately the ads (which I don’t mind having) either freeze the app or won’t close out when I try to tap the ‘X’ provided. It really halts the flow of using the app. Would love to change this rating to higher eventually if this is fixed Edit in response: Sadly the freezing of the app happens
- [R153] This app crashes at least a dozen times a day: The free version has ads and it crashes the app. Every time an ad comes up. The company knows about it. And they don’t fix it. It’s by design. They previously responded and said oh you should contact us directly because the app isn’t supposed to do that but you see all these other reviews that say the exact same thing as me and they know that it crash
- [R3] Very Buggy: I like this app but before I lay down money on the paid version they need to work out the bugs on the free version. It freezes a lot. Macro ratios dont update or match between views. It also does this weird “wipe” or blank screen every time you update macros or other info that is annoying.
- [R22] Good Potential: Quirky app. Not able to login sometimes on an iphone. On an Ipad it will rotate to portrait on it’s own. Adding daily items will not also work (very frustrating). No feature to photograph a meal and let it decipher (I would rarely use this but when dining out it’s very useful. No ability to easily track hours not eating (IF) this should be easily added.
- [R89] Great but Glitchy App: I love the features of Cronometer. It makes tracking macros much easier. My issue is that every time I make an entry a blank white box pops up. Usually it goes away on its own. But today, as I try to update my macros, every time I enter information, the white box comes up and stays. I can’t do anything when it’s on the screen except shut down the app after each change to m
- [R112] Black screen: After paying for the app, it started to pull up a black screen that would not go away unless I closed and reopened the app. It happens everytime I use it making the app almost unusable. Please send a fix quick or I will have to end my subscription
- [R13] New "dot" design is cluttered and unintuitive.: I now have to go through every macro and micro to get rid of the new dot design for unassigned nutrients. I use to be able to check my daily intake at a glance, and now I can't. Pointless and unhelpful.
- [R20] Bad color change and they won’t change it back/allow us to change custom colors: I get some apps change themes overtime, functionally it’s the same in terms of inputting data, but it is too hard to read now. Flat out they made it difficult to read and follow along with what you are reading. They seem pretty responsive on Reddit/social media and they aren’t changing it in the near future. I really
- [R25] New colors are terrible: How are we supposed to read these? Just give us the option to change it back or choose a theme.
- [R44] Please allow users to change the colors: I have benefited from this app all year, however, the latest change in colors makes it extremely difficult to read. Please allow users to set their own color choices rather than forcing them to use one set of colors. If this will not be changed, I will be forced to move on to another app which I can read more easily.
- [R72] New update sucks: The new update made everything show up alphabetically when you search. It’s not intuitive at all anymore and you have to scroll all the way down to find the most basic food. It’s a pain to use now
- [R76] Search Issues: I love this app and how it integrates with my other wellness applications. The recent update made it impossible to easily search generic items… brands pop up first and then you have to filter through everything to get to a generic item. Very frustrating and time consuming. Prior to the update, no issues
- [R82] Update made food tracking miserable: Used to be quick and easy to log food but whatever update dropped recently completely changed the order of whatever food shows up when I search foods to add. There’s no reason I have to scroll so far down to add “banana” when it shows me 3-5 pages of banana products first. All the items I typed used to be at the top of the list.
- [R128] Built for processed and packaged food consumers: The app is great on so many levels but when you try to add a food and use their search function, it is horrendous. I tried to look up cod for a cod fillet and the only thing I got were long list of products that had the letters, COD in them. I think it does a really good job at finding barcodes, but not raw real food. I have the same result for thi
- [R15] If you want SIMPLE -: This is not the app. I just wanted something to count my daily calories -that’s it. - simple - I don’t need to know what Arby’s, Sonci or any other commercial place has - I want simple by ingredient - THIS IS NOT IT it is actually easier to use google intelligence or ChatGPT tell it what you ate - ask for the calories and go -
- [R287] Certain common foods still not fully: Requested they get measurements for nettles and dandelions years ago… years later… they still haven't done it. It's frustrating as they are free foods in every British garden but I can’t log them so I have to buy other greens instead.
- [R305] Not many UK brands: I tried this app because I wanted a simple way to check micro nutrients. However, none of the brands I use are in the database. It’s not too difficult to add them but you only get information on macros, not micros and you are tied into the packaging portion size. For tracking macros, nutracheck has a better database for the UK.
- [R125] X: Program is non-intuitive and is difficult and time consuming to learn and use
- [R150] Hard to use: Not intuitive and hard to add things. MyFitnessPal is just more intuitive and faster to use. This is so confusing.
- [R188] Clunky -price is good: Milk 2 percent. I can ONLY add a cup. When I have a cup of coffee, I only add a half or 1/4 cup to coffee. In the app, I can’t change the amount. It says 100 ( what does that even mean? 100 WHATS?) and I can’t alter it. CLUNKY! CLUNKY CLUNKY! Received a recommendation from chat GBT but only a computer can use it apparently. The price is good but app is really clunky
- [R205] Not easy to use: This app pisses me off because it's just not easy to use. Let me choose the ingredient and the amount- instead it gives you random suggestions and you have to work around that. On top of that, it's not easy to go back and look at the specific macros of each ingredient that you added to a recipe or meal that you logged. It needs to be a bit more intuitive
- [R2] First Try: I can’t get out of photo loop. Paid for months ago and figured I never had a problem with My Fitness Pal so give it a go, but I wasted my money on this app.
- [R43] Great except stuck commercials: I really enjoy the app and loved how many foods come up accurately when scanned. However the commercials are terrible. I don't mind sitting through them because I chose not to pay but many times they are very difficult to exit out of and get back to the app.
- [R18] Latest update not great in dark mode: The app in general is good but the most recent color scheme update is a struggle in dark mode. The font colors are so dark for some items that they’re almost impossible to read. Please check your font colors in dark mode and consider if they’re accessible or not or give people the option to change the font colors to something more visible.
- [R38] The best by far: Already has a majority of my favorite speciality foods and supplements already in the database. I’ve used others, and none have had as comprehensive of a database, making it so much easier to stay accurate and on track. I’m only using the free version, and it’s plenty good for my goals.
- [R33] Very helpful: I can weigh my food or even the bar code. Works great
- [R158] Too many Ads: Overall the interface is great and easy to navigate. I’m currently using the free version of this app and my frustration lies with the amount of ads that come up. Simply trying to add goods to the tracker and it’s an add between every food item sometimes. While o get the ads keep the base version free there should be some form of moderation. Truthfully after this month I’m switching
