Value score / 100 Worth paying? No Skip it

Lifesum offers solid calorie tracking in its free version, but recent AI changes and persistent bugs make the paid subscription questionable.

Free + in-app purchases seen up to $119.99 4.6★ lifetime (150,086) since 2019

Lifesum is a calorie and nutrition tracker with a generally positive lifetime rating, but recent updates introducing AI have led to significant user frustration due to inaccuracies and bugs. While the free version is praised for basic tracking, the paid subscription is often deemed not worth the cost due to these issues and aggressive pop-up ads.

Free vs paid

The free version of Lifesum allows users to track calories, scan barcodes, and monitor input/output ratios, syncing with devices like the Apple Watch R3R75R154. It is considered easy to use for basic calorie tracking R10R29. However, the free version is heavily interrupted by frequent, slow-loading pop-up ads encouraging subscription R9R31R70R80. Advanced options, such as adjusting macros and accessing recipes, are paywalled R8R10R35. Some users report that the premium interface, especially with the new AI, is worse than the free version for logging meals .

Worth paying if

The paid version might be worth it if the user is not bothered by the new AI features and associated bugs, and specifically needs the advanced options like custom macro adjustments or meal plans, assuming the bugs are resolved R8R10R35.

Skip / stay free if

Users should skip paying for Lifesum if they rely on accurate macro tracking, dislike frequent app crashes and glitches, or are frustrated by inaccurate AI input and scan data R4R6R7R12. Those seeking a smooth, ad-free experience in the free version will also be disappointed by constant subscription pop-ups R9R31R70R80.

Evidence note: Reviews are heavily skewed towards recent negative experiences with the AI update and bugs, despite a high lifetime rating. Many positive reviews are older or refer to the app before recent changes.

  1. [R12] 3/5 · US Update issues: This recent update fixed some bugs but added new ones where its not showing me calories consumed anymore
  2. [R30] 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
  3. [R31] 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
  4. [R33] 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 :(
  5. [R4] 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
  6. [R6] 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
  7. [R7] 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
  8. [R18] 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
  9. [R9] 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
  10. [R70] 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
  11. [R80] 3/5 · US I was very loyal to this app.: I’ve used this app over the course of 5 years and I loved it so much! I recommended it to people and everything, but in the past year with adding AI and trying to upsell me every time I opened the app. I had to stop using it. Overall, it helped me lose weight and it has great tools. I’m finding myself using other apps more considering it’s less hassle opening the app
  12. [R8] 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. [R10] 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. [R35] 1/5 · US 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.
  15. [R39] 3/5 · US Potentially good: This app has a lot of great features, but it falls short in a few areas: -the selection of recipes is very very limited and frankly not worth the price of a premium subscription. -the daily encouragement messages on the main screen are a nice feature, but are also super buggy. It frequently thinks its dinner time at 9am and other such nonsense. -the ai language tracking is fin
  16. [R21] 1/5 · US Don’t let me restore my purchase: Don’t let me restore my purchase and very frustrating experience.
  17. [R61] 1/5 · US Charged twice for a monthly subscription: Lifesum Premium 1 year Lifesum Premium 1 year Lifesum: AI Calorie Counter Expires: Jun 3, 2026 Subscription Resubscribed Manage Subscriptions May 4, 2026 at 12:46 AM EDT $14.99 Lifesum Premium 1 Month Lifesum Premium 1 Month Lifesum: AI Calorie Counter May 3, 2026 - Jun 3, 2026 Subscription Resubscribed Manage Subscriptions May 4, 2026 at 12:35 AM EDT $14.
  18. [R3] 5/5 · US Love this app: Easy to record and review data, and gathers data from my Apple Watch seamlessly.
  19. [R5] 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! ♥️
  20. [R13] 1/5 · US Great!: So easy to use and makes me think about what nutrition I am consuming
  21. [R14] 5/5 · US Weight loss: This app is the only way I can loss weight. I love how it calculates how many calories I can eat in a day and it’s right on point.
  22. [R29] 5/5 · US Weight loss: I have already lost 3 pounds in 3 weeks I like this app it’s a good app I give 5 stars free I really like this app I would give 10 stars if I could I had other calorie intake apps but this one works best
  23. [R73] 2/5 · US Buggy as hell: Crashes, freezes frequently. Miscalculates calories in AI picture mode. Slow. Functionality keeps changing with diminishing user friendliness. Yesterday and today AI features just stopped working: photo or text input is not processed. However, I must say that with all this bugs it helped me to shed thirty pounds and maintain achieved weight.
  24. [R75] 5/5 · US Still Superb: Many years ago, before Covid, I used Lifesum on my Android phone while attending college. Fast forward to now and I am using ios, and thankfully Lifesum still has the same free resources and tracking available. I’m grateful for apps like Lifesum which offer free help for those whose income gives little leeway. It is awesome how Lifesum allows barcode tracking for free, and makes trac
  25. [R108] 4/5 · US Good if used habitually: Food scan is reliable. Food lookup dubious. Units of measure largely absurd -- ounces of Hershey Kisses? Exercise calories exaggerated, as is industry standard. Good integration with iPhone Health if used properly. Don't track exercise independently with LS and iPhone both. Recent bug makes me log in every time. Sucky new feature forces you to look at ad. Reasonable, bu
  26. [R124] 5/5 · US Fantastic app for counting calories: I love the barcode feature, it really makes it so simple to track all your calories through the day.
  27. [R154] 4/5 · US Free version is Great: The free version is great to use. I track my macros, and it scans most foods. I appreciate that some foods are verified, I can save favorites, make corrections if needed, and it syncs with my Apple Watch to monitor my input and output ratio. My only issue is that it constantly advertises the premium version whenever I use it. If it didn’t do that, I would like the app even m
