  1. [R1] Lifesum 1/5 · US 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
  2. [R4] Lifesum 2/5 · US 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
  3. [R9] Lifesum 3/5 · US Used to be better: I’ve used this app on and off for the past five years and I like it. however, the AI is egregiously off when it comes to calories and nutrition so best to search your food in the database or input your own recipes. Also the little motivational blurb it gives you are random, telling me my goal is to gain weight when I’m trying to lose weight and talking about my midday check-in w
  4. [R11] Lifesum 4/5 · US Liking it so far but wish it included fiber tracking: It’s a nice app and easy to use. The AI seems to work pretty well too. The only thing I wish that were either added to macros or just tracking in general is fiber, since most people don’t get the daily requirement for fiber but it’s so important for your health. Hoping you’ll add it in at some point but keep up the good work! ♥️
  5. [R5] Lifesum 5/5 · US Love the app but…: When I make a meal or recipe it asks for the amount of servings and the thing is I never know. It changes day to day depending on how much I want to eat and I rather it calculate the amount of ounces in the full pot and let me do my input with ounces instead of the servings . Throws off my macro calculations too
  6. [R8] Lifesum 5/5 · US Love this app: Easy to record and review data, and gathers data from my Apple Watch seamlessly.
  7. [R10] Lifesum 1/5 · US Great!: So easy to use and makes me think about what nutrition I am consuming
  8. [R3] Lifesum 3/5 · US Macros saving to zero: I really don’t like it how sometimes when you custom input your own nutrition lets say for example I know the weight and macros for X amount of bourbon chicken from Leanne Chin so I’ll take a separate AI give it my gram total have that tell me my macros for that amount and then I’ll copy paste macros Into lifesum and then sometimes later in the day it’ll sshow all zeros for
  9. [R6] Lifesum 3/5 · US Update issues: This recent update fixed some bugs but added new ones where its not showing me calories consumed anymore
  10. [R12] Lifesum 3/5 · US Was good but not anymore: After the update, it won’t save whatever food I track. I inout the calories and it doesn’t show, not sure whats wrong because the app used to work :(
  11. [R7] Lifesum 2/5 · US 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
  12. [R14] Lifesum 4/5 · US 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.
  13. [R17] Lifesum 5/5 · US Pretty good for a free app: It’s nice for being free and it’s easy to track calories now. The recipes aren’t free though which is a bummer but understandable
  14. [R20] Lifesum 4/5 · US Solid App with Excellent Support: Updated Review: I have revised my review since my last post. The LifeSum app is a very good app that allows you to easily track your nutrition and calories. Its AI features have greatly improved over the past few months and it does an excellent of automatically tracking your meal either via a picture or general description. If you need an app that tracks your calo
  15. [R28] Lifesum 1/5 · US 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
  16. [R40] Lifesum 1/5 · US 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.
  17. [R64] MyFitnessPal 1/5 · US Syncing issues: Had premium. Major issues syncing and they WILL NOT FIX IT. Just keeps getting worse. Awful. Wish my trainer didn’t use this app. Nonsense.
  18. [R49] Lifesum 1/5 · US Ai slop: Cancelled my premium because the new ai interface is gross and extremely inaccurate. I put in a full meal in the chat function to be told it was 36 calories. Making meals is a pain. They charged me anyway. I haven’t used the app in month and its cost me $50 Gross.
  19. [R30] Lifesum 3/5 · US 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
  20. [R31] Lifesum 2/5 · US Please fix this app full of glitches: Was a great app until it became almost unusable. The app freezes when I open it making me wait at least a minute to log anything. The search results can be a little wonky or the macros are often wrong in some scannable products. Finally I’ll go to log in food but it doesn’t load for hours. Also i get hit with an ad to upgrade the app to premium EVERY SINGLE TI
  21. [R79] MyFitnessPal 1/5 · US New update: The layout is absolutely trash. You should fire whoever came up with this idea. I could tolerate losing the barcode scan on the free portion but holy moly this is a major step backwards. Go back or make it way better Update: ITS GOTTEN EVEN WORSE, oh my god how do you guys change how we manage how many calories and macros we want, just put the whole app behind a paywall at this point.
  22. [R19] Lifesum 1/5 · US Loved to hated - DO NOT DOWNLOAD: I loved this app when they made it very simple. They have added so many things now and there’s bugs that make the app completely broken. For example I set my daily calorie intake to 1700 and for some reason it won’t save it and does a RANDOM calorie number. Secondly, when you select a meal plan it sets your carbs, protein and fats for you. there is NO way to remov
