Our verdict on OpenNutriTracker

OpenNutriTracker is a free, open-source calorie and nutrition tracker for Android and iOS. It suits people who want to keep a meal diary and review nutrition without a subscription, especially those who prefer local data storage and export options. Food can be logged through search, barcode scanning, or quick-add entries for calories and macros. The diary separates breakfast, lunch, dinner, and snacks, while calorie and macro goals, nutrition trends, and micronutrient views help users review intake over time.

Its local-first approach is a defining choice. OpenNutriTracker stores personal records in encrypted local storage and does not require an account or cloud sync. That can appeal to people who prefer not to maintain an online account, but it also means the app does not offer cloud synchronization. JSON and CSV export, JSON import, and QR sharing provide ways to move or share data. Food lookup draws on Open Food Facts, with optional reference databases including USDA FoodData Central and Germany’s BLS. Custom meals and reusable recipes can include ingredients, photos, brands, and barcodes.

The feature set extends beyond meal logging to activities, water, fasting, and weight tracking, making it suitable for people who want these records alongside nutrition. It remains a mobile app, and support is community-based. Choose OpenNutriTracker if free, private local tracking and data portability are priorities; consider an alternative if cloud sync or a different platform is essential. Its open-source, no-subscription model and range of food and nutrition views make it a focused option for individual tracking.
