Simple Calorie Tracker

This is a free and open source React Native application that helps you track your daily calories, macros, and meals. The design is inspired by Yazio.

Features

• Search foods by name or barcode with OpenFoodFacts and USDA api integration
• Track calories, protein, fat, and carbohydrates in a daily diary
• Add custom entries with your own nutritional values
• Save your favorite foods for quick access
• Customize your daily targets

TODOs

• Cache for USDA searches. Since the USDA databases changes very rarely, a cache for queries can be implemented without worries, with a very long invalidation time.
• Recents and frequently used foods. This could be a very handy feature for people that eat some food very ofted, like cereals, milk, eggs or this kind of food.
• Internationalization. I developed this app without multi languages support in mind, but since there is a small set of pages and components, it's not an hard to implement feature.
• Changing the day in the diary. At the moment the diary page supports only showing the current day, but having the possibility to change the day could be useful.
