- [R1] Lifesum Ai Ruined This App: I’ve used this app on and off for years and loved it. However, with the introduction of Ai to the tracking, it’s become wildly inaccurate. I can tell it the same item from one day to another and get completely different nutrition results. Not a small margin of error but massive swings. Then, you have to take the time to go and adjust every single meal. It. Becomes so time consu
- [R4] Lifesum Useless! Incorrect macros even when you scan a label: I scanned multiple labels and each time the carbs and protein and calories were input differently than the nutrition label shows them. The app doesn’t allow you to edit that info so tracking your macros with this app results in inaccurate data
- [R68] Cronometer 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.
- [R71] Cronometer 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.
- [R7] Lifesum Pop ups are so irritating: I have used this app for years both the free version and the paid version. I love it, it does everything I want it to and is easy to use. However, currently I am using the free version and the amount of pop ups to subscribe is intolerable to the point I don’t use it. Every time you open the app there is an ad to subscribe that takes ages to load. I just want to track my
- [R30] Lifesum daily user for years: The app used to be better. Now pop ups for subscriptions pop up EVERY SINGLE TIME you open the app. Since they added that "feature" the app takes forever to open and is usually glitchy until you close it and open it again. Food info isn't regulated bc it's often incorrect. I had premium for a year and i don't think it's worth the cost. you can just google recipes and the macr
- [R65] Cronometer Easy to use: Cronometer is easy to use and provides a wealth of information. It keeps me on track with my nutritional needs.
- [R66] Cronometer 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.
- [R28] Lifesum 10 months, great. Last two not so much.: I appreciate the year long subscription to this app. I used it daily and directly credit it with positive lifestyle changes. That said, the last two months were unreliable. My logs were corrupted - sometime saved, sometimes not, sometimes absent entirely (not just the present day, but weeks of data would go missing). Multiple attempts to reach out to c
- [R39] Lifesum Would be perfect if they would fix the bugs: This app is great for tracking your meals and keeping up with your macros. It would be the perfect app if only they would fix all the bugs. This app is so ridden with glitches that it makes tracking your meals so frustrating. I have issues with tracking a meal that doesn’t show up, I have issues with creating a meal that doesn’t save, sometimes I scan a
- [R61] Cronometer Lots of bugs since update: Constant crashes, multi year user. Please fix.
- [R72] Cronometer Paid tier is still glitchy: App screen keeps “refreshing” every few seconds, taking away access to all UI elements as though it’s trying to load an ad even though I’m on a paid subscription which removes ads. Photo log which brings up camera also constantly nags about giving full access to all photos on every single use
- [R14] Lifesum This is how I keep myself accountable: I love this app, but the only thing I don’t like is that you have to pay for the advanced options but you have to do that with any app so it’s really not that big of a deal I suppose.
- [R37] Lifesum Lack of Value: The fact you have to upgrade to the paid version just to set / adjust your macros yourself is laughable and provides zero value. Makes me want to just delete all together.
- [R67] Cronometer Doesn’t do as advertised: This app doesn’t do as it was advertised to me. It said we can track insulin, it can but lists just insulin. The food logging is horrible. Very little customizable displays, they put data out there that they deem you would like, it you don’t like it or like where it is too bad. There is no trial period! I wish I knew that before I dropped the $60 on this app. Find a
- [R109] Cronometer 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
- [R40] Lifesum Waste of money!: So I purchased the subscription for a year, don’t remember how much it was. Then after using it for a few weeks or a few months the I noticed I was staying below my calories and still gaining weight. So I downloaded a different app and the cals were off on Lifesum by a lot. I emailed them asking for a refund and never got a response back. So yeah don’t waste your money.
- [R84] Cronometer Great customer service: I faithfully track everything and it’s easy to do. However I have noticed on some items the calorie count is different from the labels. It might not be off by a lot, but it doesn’t match. Their customer service is very helpful.
- [R96] Cronometer Good concept but sloppy programming, poor execution, lack of useful customer service.: Cronometer is probably the best nutrient tracker out there but the company has quite a way to go before it is remotely world class. Programming is very frustrating and unfriendly on anything custom, measurements units are non standard and crazy across foods, no noticeable continuous programming improvement or m
