Improvements and tweaks to help you build and be your best

Recurring themes

Subscription & Billing negative
Many users report being charged unexpectedly after a 'free trial' or immediately upon setup, even after canceling. There are frequent complaints about difficulty getting refunds and poor customer service regarding billing issues. The app is not free to use, despite ads suggesting otherwise.R1R2R4R5
Accuracy & Database negative
A significant number of users find the AI food recognition, calorie counts, and portion size estimates to be inaccurate. The food database is often described as limited, especially for restaurant items, international foods, or specific brands. Barcode scanning also frequently yields incorrect information.R4R10R11R13
Technical Issues negative
Users frequently report the app freezing, crashing, or experiencing significant lag. Issues with Apple Health synchronization are common, with data not writing correctly or consistently. Some users also experience problems with the AI scanner or barcode reader not working.R3R12R16R19
Effectiveness for Weight Loss positive
Despite the issues, several users credit the app with helping them lose weight and stay motivated. They find it useful for tracking calories and progress.R6R7R9R23
User Experience & Features mixed

Who it's for

This app is for individuals primarily focused on weight loss who are willing to pay for a calorie tracking solution and are comfortable manually correcting potentially inaccurate AI or barcode scans R6R7R99. It may appeal to those who appreciate a simple interface and the motivation of tracking, but it is not for users seeking a free app, highly accurate food recognition, reliable Apple Health integration, or robust customer support R2R12R15R57.

Evidence note: The recent reviews skew heavily negative, particularly concerning billing and accuracy issues, which contradicts the high lifetime rating. The developer's release notes are too vague to address specific user complaints.

  1. [R6] 5/5 · US 5 star: Works really well helped me lose weight I will recommend
  2. [R7] 5/5 · US Teacher champ: This app is the best I lost 11 pounds in a few weeks
  3. [R9] 5/5 · US Best diet app ever: I used for a month and lost 3 pounds
  4. [R99] 5/5 · US USE THIS APP: I started using this app in late December 2025 weighing 270 pounds. Today is June 17 and this morning I weighed in at 219. The reason I know this app is what worked for me is because I don’t do anything now that I didn’t do in December except use this app to keep track of calories and nutrients. I walked back in December and I walk now. That’s it for exercise. I thought I would give
  5. [R56] 3/5 · US Good, not great: I love the idea and ease of use for tracking calories and macros, but it still needs a good amount of work. They need to add a way to save multiple items into a “meal” since some of us eat the same meals consistently. Also the food database is pathetic. I’ve only been using it four days now and have had to correct four or five meals already. I’m going to give this a chance because
  6. [R90] 5/5 · US Fast and easy to use: The white background makes it easy to read and I love how fast it scans food and labels
  7. [R191] 3/5 · US Convenient but inaccurate: Very easy to use, but the portion estimates are way off. To test this I used a food scale and found it estimated 8oz of chicken breast to be 6oz. Good for keeping a food diary but not for calories and macros tracking.
  8. [R44] 3/5 · US Great App - But Needs Improvement: First of all, the aesthetic of this app is fantastic. The AI is also shockingly accurate. HOWEVER, the food database needs a drastic improvement. If you travel and you have to eat out a lot, easy things like a McDonald’s Burger with no bun are not in this system. There’s an only a few fast food items and they all seem to have odd names associated with them. Im gi
  9. [R67] 5/5 · US Surprised at how good it is: I’m pretty amazed that it can even identify japanese home cooked meals. I love this app. Fun to use too
  10. [R150] 3/5 · US No sincroniza y bug en manage personalization preferences: Great idea, but important features are broken I really like the concept and the AI food recognition is excellent, but there are two major issues that significantly reduce the app’s usefulness. 1. Apple Health integration doesn’t work correctly. Even with all Health permissions enabled, Cal AI does not write nutrition data (calories, carb
  11. [R1] 1/5 · US Misleading Trial offer!: When I clicked 3 day trial it charged me 29.99. I tried to reach out to customer service and they didn’t reply.
  12. [R5] 1/5 · US Scam: Such a bad app I have been getting money taken out of my account monthly when I only choose the $30 per year choice but every month it’s been charging me $30 and there is no way for me to get a refund and I have all the evidence through pictures to
  13. [R15] 1/5 · US inaccurate and dishonest: they charged me for a subscription even though i had cancelled basically immediately after signing up for a free trial. they ai tool is also very wrong-you would probably be best just guessing the amount of calories in a meal.
  14. [R21] 1/5 · US Rip off: I subscribed to the app, which was $30. I attempted to cancel (within the free period) and it still charged me $30 for the purchase. I emailed and tried to contact customer service in order to receive a refund and they did not email back. Do not use. I would not recommend to anyone.
  15. [R2] 1/5 · US Money grab: I’m truly disappointed. I never leave reviews for anything but this is another level of pathetic. I couldn’t even finish setting up the app because it has you sign up for the paid subscription.
  16. [R14] 1/5 · US Not free: I came into this app thinking I was going to lose weight but the only thing they want you to lose is money
  17. [R17] 3/5 · US I have to pay: I didn’t get to try it because I wasn’t going to pay and I was ready to lose weight I saw a bunch of ads on yt thinking it will be nice but I didn’t even get to try it I gave it a 3 star because I think it would be good if you payed for it
  18. [R20] 1/5 · US Scam: Forced to pay a monthly plan. Should be up front about that. Deleted
  19. [R10] 1/5 · US Not accurate: Did my own calculations and compared it with another food app and with Cal AI. Not accurate and no conversions
  20. [R11] 2/5 · US Everything it does myfitnesspal does better: Cal AI really struggles with identifying portion sizes, which is what I hoped it would be better at doing than MFP. It struggles to count clearly visible food items, like cherry tomatoes. It will routinely get the number of things wrong. It also can’t read the nutrition information on a label that you scan, so you have to manually change everything an
  21. [R46] 1/5 · US Very inaccurate: I would log the same meal and it would give me a different calories suggestion every time. Not at all accurate. I’d stick to a proper calories tracking up instead such as MyMacroes+
  22. [R68] 1/5 · US Don’t waste your money: First of all the fact that they don’t have a free trial is ridiculous. They claim you’ll lose 4 lbs in a month but I gained weight using this! Their calculations are way off, for example I used this on Belvita bites and they clocked it as more than twice as many calories.
  23. [R12] 3/5 · US Synch issues: I really like this app after using MyFitnessPal for years I tried Cal AI and I really like it a lot. The issue is the sync to apple health is unreliable. It syncs some entries and not others. so until they figure that out I’m going back to my fitness pal
  24. [R80] 3/5 · US Link to Apple Health Substandard!: I like using this app it takes the effort out of monitoring my exercise, and calorie intake. However, I have linked it to Apple health and it has only retrieved my weight four times in about two months! I’m sure this is an easy fix. Can you fix it?! As I am paying for this app, I should have access to Support.
  25. [R176] 3/5 · US Fix Apple health sync issues: It’s not writing data to the heath app. Love it but pls fix asap. 3 stars until then
  26. [R3] 2/5 · US Freezes a lot: I give this app a 2, it’s great when it works but it’s freezes constantly. Please fix the freezing problem!!
  27. [R69] 3/5 · US Buggy: App works ok for tracking my food but the last week I’ve been using it it just keeps freezing.
  28. [R256] 3/5 · GB Too slow: App glitches a lot, crashes when I try to log workouts and is more of an annoyance to use than it’s worth.
  29. [R269] 3/5 · GB Lag: I’ve been using this app for a while, bought a year membership and it’s gotten super laggy recently and whenever I log a food I have to wait for a solid 20-40 seconds for it to respond
  30. [R16] 1/5 · US No response: I put in the incorrect weight when I joined. Now I can’t fix it and it is not giving me the correct data. I tried to delete my account and start again, but it went back to the current weight. I sent an email to the address on the app, but nobody has contacted me back.
  31. [R57] 1/5 · US I’d hold off on buying this app.: I’d hold off on buying this app. Mine has been malfunctioning for more than a month now, and despite reaching out to Cal AI customer support several times, I keep getting the same canned response: “we’ll look into it and get back to you.” No actual fix, no real update, just the same line every time. At this point, it feels like the company is more focused on colle
  32. [R13] 3/5 · US Restaurant data weak: I’ve been using this app for over a year. But when you eat out, they have very few foods from each restaurant is you can find the restaurant at all! That needs improved.
  33. [R203] 3/5 · GB My fitness pals younger brother: I accidentally purchased the premium version so thought Id give it a go since ive already paid the money. And i think ill just be going back to using the free My fitness pal. The suggestions are rubbish and the lists are small. The barcode scanner doesnt always work. And often find im having to correct macros. Shame really cus it looks the part but i just dont dins
  34. [R81] 2/5 · US Saw the advertisements thought it would be amazing: I just added a food using the barcode and it was still wrong! I don’t understand how an app can be so wrong especially when I scanned the barcode! This app is horrible I have to add everything in myself! The idea was awesome if they could actually make it work correctly though. I still use it to keep track of my calories but it’s always wrong and
  35. [R125] 3/5 · US Not bad, needs refinement.: It works well enough but it’s lacking core features for any real consideration, namely integration with other fitness software and trackers (ie: Garmin, FitBit, etc). Apple Health is largely useless to any people who train seriously. That’s the big issue with it for me. Aside from that it’s a bit clunky and unfinished feeling, bar caode scanning is pretty bad and does
  36. [R18] 1/5 · US Language: App no language persian and is bad
  37. [R28] 3/5 · US dil destegi: ingilizce sz cok biliyorum fakat türkçe gelse iyi olurmus bunu bilmeyen kisilerde yuklicek bence dil destegi ıyı olur birkac dil daha eklenilebilir
  38. [R25] 2/5 · US Works but…: It does supposed to do, but I don’t like that if you forget one day to update what you eat, you lose your streak and then they want to charge you to keep it going. It just makes me not want to use the app altogether take away that and the app is perfect.
  39. [R27] 2/5 · US Money scam: I appreciate that it counts calories. Although it isn’t accurate it does help. But what i don’t appreciate is me being penalized for the app’s inability to log calories and costing me my streaks. Should fix the issue.
  40. [R131] 3/5 · US Needs work: It has glitches. We should be able to upload photos instead just scanning them. Also if you stop for a day it charges .99$ to restart. Which is ridiculous since we pay for it a year subscription. The app needs to get better
  41. [R4] 1/5 · US Seems good at first: If you get those ads about the about eyeball in your calories so AI do it and it seems good to start off like to kind of keep track your calories a quick easy way but this app is so stupid because you’re just letting an AI judge what you eat off a 2D picture and then on top of that you’re paying 30 bucks a month and my issue with that is that they’re trying to charge me $120 e
  42. [R19] 2/5 · US Scan Food Function Stopped Working: Was loving the app functionality and connectivity with my Apple Watch workouts. All of sudden two days ago the scan foods option stopped working. Please fix the app or tell me how to get it working.
  43. [R23] 5/5 · US Best app: This app really works
  44. [R8] 5/5 · US Cal ai: Good question and overall really good
  45. [R22] 4/5 · US Chat groups: The only issues I have is that they only have 4 group for chats. They need more specific groups to join. We have so many questions in the general groups that could be split into various group chats. PLEASE have the app developer create more groups or give us the control to do that. The other thing is notifications when someone leaves a reply to your comment or if you reply to someone
  46. [R30] 1/5 · US Just wasn’t for me: I downloaded the app when I was weighing 145 pounds and I was trying to cut 10 pounds before the end of summer. The app told me it would take THREE MONTHS before I will get to that way so I gave up on the app completely and started doing my own thing and now I weigh 135 and it only took me a month
