Sans frustrée, elle vous apprend où se trouve les défauts dans votre alimentation. Merci beaucoup ### 4/5 — Open Source! *2026-08-22, version v2.0.2* Thank you for providing a open source and free calorie and nutrients tracker app! I greatly appreciate that, and once it works as it should I will buy you a Kofi :) however, for the time being, some things need honing, foremost the search for products. I cannot set the app to English and if I search the German product names, standard products such as "cream", "flour" etc are just not available, which really limits what you can track. Also it is not easily possible to set the individual calorie goal besides what the app calculates. Update: I did change the language to English and was now able to find basis products, but the calories of those are completely off. ### 3/5 — Update teilweise gut *2026-08-09, version v2.0.2* Ich finde es jetzt etwas unübersichtlicher nach dem Update. Außerdem wurde der Fehler mit den Natrium immer noch nicht korrigiert. Manche Nahrungsmittel haben uum Beispiel nur 0,3 mg Natrium anstatt 0,3 g. ### 3/5 — Five stars but.. *2026-07-27* It tracks you. Please make this the only calorie counting app available on IOS that doesnt track you. Being the only app would make you the defacto top choice for anyone paying attention to the surveillance and police state. Help remove the fascists. Please!! 🙏 (being the peoples champ is alot better than being anything else) ### 5/5 — straightforward and all in one *2026-07-11, version v1.5.0* i like how it has weight tracking and calorie tracking, and it is easy to add all the details of your meals yourself. It is very helpful and awesome!!!! ### 4/5 — Struggling But Grateful *2026-07-09, version v1.5.0* I’m excited to work with a non-commercial nutrient tracking app. But, on initial use, I’m really struggling to log my meals. When I click to log a meal, I don’t see any of my custom foods or recipes without searching or going to “recents”. Why wouldn’t my foods always be there, or maybe a tab for my foods? It’s not there. In order to use the app efficiently, I need to create custom meals. But, the “simple” method seems to have a default serving size of 100g which cannot be changed. The “advanced” method allows me to set a meal size and/or serving size as a default “total amount”. And, then there’s a “base quantity” which allows me to set the “serving size” which is again by default 100g. It’s just really confusing, not to mention the results for foods seem to be a combination of all users custom foods and scanned foods. I’d like the option to not show other’s custom foods or recipes, and instead have a basic database of staples like “eggs”, “bread”, “whole milk”, etc. It’s really cluttered when searching. For scanning every food with a barcode, it’s petty great. But still, for recalling common foods, it requires an inefficient process of first tapping recent, then scrolling. I’m hoping it’ll get a “my foods” tab which opens by default when adding a meal, and the most recent foods scanned or added will be there. ### 5/5 — Blazing Fast *2026-06-03, version v1.5.0* No ads, no paywalls, no bloat, no bs. You can export your data at any moment, or import some from somewhere else, no questions asked. I have experienced no bugs in these last few months. Developers are still active on the repo, so I’m expecting it to get even better. ### 5/5 — Free, privacy-focused, but slightly complicated *2026-06-03, version v1.5.0* I love this app because it’s free, doesn’t have ads, and all your data is stored only on your phone. I believe they take some anonymized metrics but it’s not much. Setting it up is slightly unintuitive / complicated but once you get it figured out it’s smooth sailing. It’s not as easy as Lose It or other calorie trackers, doesn’t have HealthKit / Apple fitness integration, but it’s pretty solid if you just want to track your intake and stay on top of deficit. The food database is slightly frustrating since probably a third of what I eat either isn’t in there or there’s an error when I scan the barcode, and I end up having to create a custom food or meal. I do feel like the math in the app is not always 100%, but what fitness app’s math is going to be true to what’s actually going on in you? I think it relies a lot on your BMI, and even as a highly active adult it still put my daily suggested kcal intake way too high for what I would consider a deficit- so I decreased it by about 500 kcal. Other than its quirks this app works well and accomplishes the task of nutrition tracking for me and I respect the privacy on it. I would recommend if you have the time to set it up (probably takes 20 min TOPS to get everything in and get used to it) and log possibly missing foods. ### 5/5 — Nutrition Meets Privacy *2026-06-02, version v1.5.0* The most recent version puts this open source nutrition tracker among the best resources out there - all while respecting your privacy through free and open source software. If you care about your fitness and care about having control of your data, look no further! ### 3/5 — I like it but *2026-05-27* It needs updates. Some that come to mind: Daily water tracker More freedom with implementing generalized meals with custom macros (relying on some open database isnt enough) More info about Green/Red Success/fail days on the calendar (such as why its red) Custom pictures for recipes Fix onboarding with height Stop collecting data / privacy ## Frequently asked questions about OpenNutriTracker ### What is OpenNutriTracker?
