  1. [R2] Cronometer 5/5 · US 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
  2. [R8] Cronometer 5/5 · US 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.
  3. [R56] Cronometer 5/5 · US 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.
  4. [R66] Cal AI 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.
  5. [R5] Cronometer 5/5 · US Easy to use: Cronometer is easy to use and provides a wealth of information. It keeps me on track with my nutritional needs.
  6. [R14] Cronometer 5/5 · US Helped me get shredded: Great app, easy to use
  7. [R64] Cal AI 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!!
  8. [R81] Cal AI 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.
  9. [R1] Cronometer 2/5 · US Lots of bugs since update: Constant crashes, multi year user. Please fix.
  10. [R3] Cronometer 3/5 · US 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.
  11. [R63] Cal AI 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
  12. [R90] Cal AI 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
  13. [R43] Cronometer 2/5 · US Deleted right after I got it: So basically I downloaded the app thinking it was going to be free but immediately subscriptions popped up to be a part of the gold member which gives you cases to everything so if you don’t pay for it you don’t get like anything that it says will give with the app. You can’t use the scan or picture thing if you don’t have it so you have to search up every single thin
  14. [R55] Cronometer 2/5 · GB Crippling Ads and Punishing Premium Price, A Demotivating Experience: I’ve used Cronometer on and off for years, and while its tracking capabilities are excellent, the recent ramp-up in advertising crosses a line. It’s not just intrusive, it borders on bullying. Full-screen ads and constant upselling, grind away at already-fragile motivation. For anyone struggling with consistency, self-discipli
  15. [R61] Cal AI 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. [R79] Cal AI 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. [R12] Cronometer 3/5 · GB Great app but serious Apple Health sync issue: I really like Cronometer for tracking nutrition, but lately there’s been a major problem with Apple Health integration. The app keeps duplicating my Active Energy balance. If I leave both Active Energy and Workouts enabled, I end up with double calories recorded. The only workaround I’ve found is to turn off Workouts, manually run Backfill every day,
  18. [R41] Cronometer 2/5 · US 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.
  19. [R85] Cal AI 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.
  20. [R97] Cal AI 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.
