What's New in OpenNutriTracker

v1.5.0

May 28, 2026

Search is now faster and more helpful, with better product detail, improved hydration of OFF results, and a boost for foods sold in your country. Base-food results without photos now show clear emoji labels to make browsing easier. We also improved logging with a pinned add button, easier quantity editing, cleaner meal details, and easier access to medical sources from onboarding and Settings.

Free, privacy-focused, but slightly complicated

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.

Nutrition Meets Privacy

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!

I like it but

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

HealthKit integration

Daaamn! This app is straight fire, I really love the UI... But it’s a real bummer that there’s no Apple Health sync. It would be super cool to fetch data and sync it back. Hope to see this feature ✊🏻

Can’t believe it’s free

Exactly, what I’m looking for
Clean UI
Nice DB
NO ADs

Can’t thank you enough
