A private, local nutrition tracker for Android, powered by Health Connect.
By default, Sustenance is read-only and beautifully displays your Health Connect data with customizable goals.
And if you supply an AI Studio API key, Sustenance can talk to Gemini to log data, too.

- Home: view your daily progress with context-aware greetings and helpful chips.
- Summary: daily averages vs. goals you set, with progress rings and comparison to yesterday.
- Pull-to-Yesterday: pull up from the dashboard to quickly view previous days.
By adding a Google AI Studio-formatted API key, Sustenance is able to analyze photos of food items and write relevant nutritional information to Health Connect.
