## What it is
OpenNutriTracker is a free, open-source calorie and nutrition tracker for Android and iOS built with Flutter. It logs food intake against calorie, macro, and micronutrient targets computed from personal stats, keeping all data on-device with a privacy-first design.

## Use cases
- track daily calories and macros on my phone
- log food with a barcode scanner
- count micronutrients in my diet
- track intermittent fasting windows
- find a private alternative to MyFitnessPal
- keep a food diary without an account
- calculate calorie targets from my height and weight

## When to choose
- you want a FOSS, privacy-respecting calorie tracker with no data leaving your device
- you need Android and iOS support from one codebase
- you want barcode scanning and Open Food Facts integration
- you value self-contained local data storage

## When to avoid
- you need cloud sync across many devices or a web interface
- you want a large verified food database with restaurant menus
- you need professional dietitian or medical meal-planning features
- you require wearable or smart-scale integrations
