What the developer says changed (the verdict above weighs this against what reviewers report):

We're so happy to see you're using Yazio to reach your goals! To help make things even easier for you, we've made further improvements to the app. Good luck!

Recurring themes

User Interface & Experience negative
Many recent reviews express strong dissatisfaction with the new UI, describing it as 'disgusting,' 'outdated,' 'clumsy,' and 'unwieldy'. Users dislike the 'gamification' elements like diamonds, streaks, and mascots, finding them childish and distracting from the core function of calorie tracking. The app is criticized for requiring too many taps to log a meal and for having excessive 'filler screens' and pop-ups.R1R5R10R12
Bugs & Performance negative
Users report frequent app crashes, especially after recent updates. There are issues with the barcode scanner locking up and the pedometer not functioning. Some users mention that graphs of past results have disappeared after updates and that goals keep resetting. The developer's notes mention 'further improvements,' but reviews suggest new bugs have been introduced or existing ones persist.R2R8R13R24
Subscription & Pricing negative
A significant number of reviews accuse the app of misleading subscription practices. Users report signing up for what appears to be a free trial or monthly plan, only to be charged for an entire year upfront. Many feel there is no genuine free trial to test premium features. There are also complaints about difficulty canceling subscriptions and being charged despite cancellation attempts.R3R9R25R26
Food Database Accuracy & Editing negative
Users frequently report that nutritional information in the database is inaccurate, with wrong calories, portion sizes, or micronutrient values. There is frustration over the inability to edit titles of imported items or correct incorrect data, even for 'blue checkmark' items. Some users find the food options limited, especially for specific regions like Canada.R17R35R50R55
Integration & Features mixed
While some users praise the app's comprehensive features for tracking and fasting, others highlight missing or poorly implemented functionalities. Syncing with Fitbit and Garmin watches is reported as unreliable or non-existent. The AI photo recognition feature is often inaccurate and cannot be turned off. Users desire the ability to add more meal times, customize fasting plans, or have offline use.R11R14R15R21

Who it's for

YAZIO is for individuals looking for a comprehensive calorie and macro tracker with fasting features and a large food database, especially if they are comfortable with a potentially intrusive user experience and are willing to pay for a premium subscription. It may appeal to those who appreciate a 'gamified' approach to tracking, though many recent users dislike this R10R23.

Evidence note: The recent reviews skew heavily negative (0.52 recent-negative signal), which contrasts sharply with the lifetime rating of 4.7. This indicates a significant decline in user satisfaction following recent updates. The developer's notes are vague and do not address specific issues reported by users, such as bugs or UI changes. Evidence for positive points is primarily from older or less detailed reviews, while negative points are strongly supported by numerous recent, detailed complaints.

  1. [R11] 5/5 · CA Fantastic App for food tracking and fasting: I don’t know how I found this app, but it is fantastic for tracking calories, carbs, protein, fat, etc. I has changed my life and make it easier if you want to get into intermittent fasting. This app is so complete that I recommend it to everyone I meet. Especially if you are a diabetic and have to watch for carbs intake, this is the best. It can read t
  2. [R73] 5/5 · CA Great app: I’ve been using it for years, and it is a great app: - it has a great library of food options - you can customize recipes and foods - it connects to your fitness apps - the interface is visually appealing - it has great micro and macronutrient summaries for the day - you can incorporate fasting - the price is right I don’t foresee myself using any other food tracking app. Keep up the
  3. [R58] 5/5 · CA Yazio: Très bonne application, sa calcule tout, tout ce d’on on a besoin. Ils y a des millier de recettes pour les personnes au régime ces super, en ce moment je suis au régime et grâce à leur recette j’ai perdue quelque poids en moin de 2 semaine. Super applications je vous le recommande fortement!
  4. [R63] 5/5 · CA Vraiment Génial !: J’utilise cette application que depuis peu, mais je trouve qu’elle est vraiment géniale. Elle est simple d’utilisation et très complète. La recherche d’aliment est vraiment super bien et à date, tous les aliments que j’ai scanné étaient répertoriés. C’est aussi très facile de trouver un aliment en l’inscrivant dans la barre de recherche et les aliments sont bien indiqués en fran
  5. [R4] 5/5 · CA Well made: Im originally very underweight for my height and age so seeing this app I wanted to test if it would just let me get lighter and was glad to see an app like this actually care to not let someone go way too underweight and instead try to guide them to gain the weight instead to a healthy minimum they should be, other then just trying to drill a dangerous road of loosing more weight!
  6. [R97] 4/5 · CA suggestion: user friendly and easy to use. however as someone with Cystic Fibrosis i think that adding a “high fat” category would be helpful, and might be fitting considering that there are options to pick meals only with very high calories (700 or more) and categories to that include other high level macros (high protein). understandable if the developers would prefer to keep the meals on a “wei
  7. [R62] 5/5 · CA I REALLY LIKE IT: There are almost every foods(even my country's(Korea) foods), and it really helpful to a diet, because I can see calories of what I ate and see what nutrients am I missing!! It really really nice.. No ads and no payment!! I will say it's the best app ever for a diet😊❤️
  8. [R49] 5/5 · CA Best App There Is For Free: it may not be the best against the premium versions of other apps but the you have much more free features here than on any other app this its the GOAT
  9. [R57] 5/5 · CA love this app!: this app is so great im using the free version and its helped me so much! i definitely recommend this app, ive been trying to loose weight and then i found this app and decided to try it and its been awesome
  10. [R1] 1/5 · CA Worst interface: I used to try other tracker apps and they were way better than this. I can’t see the weekly calorie counts on the dashboard, and couldn’t find accurate breakdown of the foods and repeated same annoying suggestions or good job, high fiber, high protein and the monster tumble affect with haptics. I can’t even stand 1week for that interface and waste my money for 1year subscription.
  11. [R5] 1/5 · CA unwieldy - horrible UX design: i used to love this calorie tracker, i even have a yearly subscription. but with this recent update and overhaul this app has become impossible to use. why does it take me five taps just to log one meal? why are there so many filler screens? i dont CARE about how long my streak is or whether i earned a “freeze” i WANT to log, get out and go. some of us have lives an
  12. [R12] 2/5 · CA About the new UI: Personally I preferred the simplicity of the previous UI of this app before the change with the mascot and the new design. I feel as if this new design just doesn’t feel as good and I find the mascot as the app logo doesn’t make sense considering it’s a calorie tracking app. Overall though still satisfied with the app itself.
  13. [R19] 1/5 · CA PLEASE DON’T MAKE A NEW UPDATE: The new interface is DISGUSTING! It seems like it was made in 2010… I always use this app and really enjoyed it until this update… Any chances to keep old interface?
  14. [R10] 2/5 · CA Great app, ruined by annoying pop-up’s: I really like YAZIO, but the constant pop-ups like diamonds, flames and other “rewards” make the app frustrating to use. Most users just want a clean and fast calorie tracker, not slow and childish interruptions every time we log food. It would help a lot to have an option to disable all these gamification elements. The app would feel much more professional
  15. [R23] 1/5 · CA Makes Paying Customers Suffer…: The design for the app feels misdirected. It’s attempting to duolingo-ify itself by adding flashy animations and pop-ups every time you take down a meal while also lacking key design features, making it feel like it doesn’t respect the user. I pay for a subscription - I should have the ability to TURN OFF POP-UPS (I am not a child?!), determine what my exact number
  16. [R27] 1/5 · CA Way too many ads & cutscenes: Open the app just log your meals and it tells you 100 different reasons why you should get premium. 10 clicks, animations you can’t skip… Not to mention that signing up took forever with all their random questions. I’d switch if I didn’t already have my information on this app. Ended up deleting the app. Easier to GPT than click through 500 ad slideshows.
  17. [R2] 1/5 · CA Too many bugs: This app has too many bugs.
  18. [R8] 1/5 · CA Why: The app crashing just shows how unnecessary all of these new updates are. Like seriously?? This is ridiculous and the updates are slow and ugly. Fix it
  19. [R13] 2/5 · CA Not Worth the Money: There are quite a few good things about this app but unfortunately there are parts that stopped working during the first week after I bought a year’s subscription and paid in full up front. I went to the subreddit and tried to figure out if the bugs would be dealt with. These issues have never been fixed and after several weeks I decided to cancel my subscription, effective Ju
  20. [R64] 3/5 · CA Used to be good: This app used to be a fantastic app. I've been using it for years but with the increased number of ads and non-stop promotion of the premium features, it's no longer useful for a quick tracking of daily calorie intake. It's been crashing a lot more too.
  21. [R17] 3/5 · CA It works but…: One thing that bothers me a lot is the inability to edit the titles of imported items. These items are sorted by title, and these titles are determined by the company that produces the product. So, we search our list for a product in normal alphabetical order, but we can't find them because we have to search first by company name. For example, in my list I have canned fruit. I can'
  22. [R50] 2/5 · CA Not bad but waayyy better out there: After using it for a month and paying for the subscription I realized how wildly inaccurate the calories for most things where, I shouldn’t have to double check the app and have to google everything and so the math to make the app match. It also wouldn’t connect to garmin or Fitbit, only apple health.
  23. [R55] 2/5 · CA They’ll take your money for what: Nutritional information on a lot of foods is incorrect as it been added by customers and requires constant editing. YAZIO does not ensure info correctness. And if you don’t interact with the app on a continual basis you data can be lost. I lost months of my data after being out of the country fo 3 weeks with no continued connectivity. Upon return my data was not r
  24. [R66] 2/5 · CA Macros don’t match the label: Great user interface, much nicer than the concurrency. But many of the food on their database have wrong information that don’t match the label (even the ones with blue checkmark) and there’s no way to change it or to at least report the mismatch. Contacting support is useless, they take long to answer and keep asking useless questions to avoid the issue
  25. [R9] 3/5 · CA It’s not free trial for pro functions: I used this a few years ago and am coming back. The promotion page says that there are 7 day free trials, but then my account was deducted by the annual fee almost a day later. So it’s not really something that makes me feel comfortable. Other than that, the functions themselves are good, I do like the UI too, so I will keep the subscription. … but it shouldn
  26. [R25] 1/5 · CA A scam!: It wouldn’t let me cancel. In fact it said it was already canceled but charged my card $50 anyways. I had already reached out to help to cancel and it still charged me. Do not accept the free trial it will not let you cancel before it charges you and it does not provide a service that isn’t available free across the App Store.
  27. [R26] 1/5 · CA They stole 23$ f: I literally unsubscribed to it and i never use it anymore then they literally took from me 23$ like thats a whole scam
  28. [R32] 2/5 · CA Ne careful before subscription: Be careful before subscription. The way payment offers is presented makes it Seem like you’re signing ou for a monthly plan, but in reality, They charge you for the entire year upfront. This feel misleading and dishonest. I tried Azio just to test it out, looking for an app to track calories, but I ended up paying for a full year for something I don’t even like.
  29. [R21] 4/5 · CA Outil fantastique pour le suivi de santé, quelques améliorations à faire: L’outil est fantastique dans l’interface utilisateur, facile à utiliser et présente bien les informations. À améliorer selon moi: * La synchronisation avec les montre Fitbit laisse encore à désirer, pas fiable. C’est dommage, cela pourrait être plus intégré aux informations collectées automatiquement. La reconnaissance AI de
  30. [R38] 3/5 · CA Pretty good: Better than my fitness pal but doesn’t connect to my Garmin watch. ): Some macros are off and it keeps resetting my goals and it’s kind of annoying.
  31. [R72] 2/5 · CA Buggy app, poor sync with Apple Watch: The app is fine but considering the cost, really shoddy and in need of improvement. I use it only for tracking food and I am sure the developers can do better.
  32. [R15] 4/5 · CA Super good app, but should automatically add burnt calories to your calorie intake count: I really like this app so far (although the photo ai feature isnt accurate, its still got most foods in the system if you just look them up or scan the bar code, so i dont really mind/use it) but one thing i think they should change is to start adding burnt calories, specifically from your step count, to your
  33. [R29] 1/5 · CA Terrible AI feature adds time to logging meals: The AI feature stands for Artificial Idiot as it is wrong 90% of the time and adds calories to your daily count. They won’t let you turn it off. Save your money.
  34. [R52] 4/5 · CA AI: I would give it a 5 star if it had AI calorie tracking where you can take a photo of your meal and tells you the calories on your plate. I think that’s starting to become the new modern calorie tracking method so please add that feature!
  35. [R48] 4/5 · CA Presque parfait, à une chose près….: Super appli ! Je donne 4 ⭐️ car on ne peut pas ajouter les temps de repas et ce serait tellement mieux pour se contrôler et contrôler notre nourriture! c’est tout ce qu’il manque pour que l’appli soit parfaite…J’espère qu’il y aura un jour une mise à jour avec cette option!
  36. [R65] 4/5 · CA Parfait mais.. Perfect but..: J’adore cette App! Combiner avec de l’entraînement j’ai perdu 15 livres en 7 semaines et maintenant je stabilise. Ma grande déception est de ne pas pouvoir crée d’autre temps de repas. Je mange moins mais plusieurs fois par jours alors je dois partager l’information séparément :( ❤️❤️❤️❤️🖤, , I love this App! Combined with training I lost 15 pounds in 7 weeks and
  37. [R84] 1/5 · CA Useless - try before subscribing.: Can’t allow me to adjust my fasting plan, I want OMAD, it only offers 16:8, it insists on distributing calories over meals across the day, and do many other dumb stuff that there is no mean to adjust to your own goals. Wasted subscription for one year, don’t subscribe be before trying it out first, I hit fooled by the good reviews.
  38. [R88] 1/5 · CA On peux même pas changer les donner: Sérieux c’est quoi cett application qu’on peux même pas changer les heures comme on veux même après avoir fait éditer , on peux même pas rajouter les jeûnes qu’on a fait dans les journées avant , je regrette d’avoir acheter
  39. [R24] 3/5 · CA Graphiques disparus: Une mise à jour de l’application à fait disparaître l’option de voir les résultats antérieurs sur un graphique. J’appréciais beaucoup cette fonction.
  40. [R3] 2/5 · CA Pas moyen de tester la caméra: Il faut payer pour tester l’option IA avec caméra. Donc après un questionnaire long et pénible, pas moyen de voir si ça fonctionne san que l’app force dans le fond la gorge l’option premium. Et mm pas moyen de payer un mois!!! C’est trois mois minimum
  41. [R35] 1/5 · CA Don’t bother if you’re in Canada: Basically zero food options, better off using MyFitnessPal. Can’t believe I wasted $25 on this. There is a reason you can’t get a free trial, no one would ever subscribe!
  42. [R14] 5/5 · CA Great: Would be great to have an option to add/snap more than one picture to the AI tab. For example protein bar itself and nutrition facts at the back of packing. That will help to count calories with greater precision
  43. [R53] 1/5 · CA It sucks!: Wasted my money. My fitness pal better and has a free trial. This SUCKS! There is NO free trial. They lie!!!!! If I could have tried it first I NEVER would have wasted my money! Mad!
  44. [R60] 1/5 · CA Be careful!: There is no monthly payment or free trial. It will make it seem like that, then charge you $50 for the entire subscription. Dirty!!
  45. [R77] 1/5 · CA HORRIBLE: The fact you can’t try the full app without paying first is a testament to the company knowing the app sucks. If they were confident it was a good app they would offer a free trial. Also, even with the free version, it was garbage. The calorie vs food and amount is incorrect. I inputted a food and it offered the amount and calories and it was not what was on the box so not sure where t
