Healthio is a minimalist, privacy-focused Android health dashboard designed for intermittent fasting, calorie tracking, and workout logging. It emphasizes a "Snap & Go" interaction model with AI-powered food analysis and seamless integration with Google Sheets for data sovereignty.
- Flux Timer: A visual, intuitive timer for Intermittent Fasting (16:8 default) with clear "Fasting" and "Eating" states.
- Smart Vision (AI Nutritionist): Snap a photo of your meal, and Healthio (powered by Gemini AI) analyzes it to estimate calories, macros, and provide a health score with feedback. Simply take a picture, and it is automatically sent to Gemini for instant analysis and logging into your dashboard.
- Energy Dashboard: Track your daily Calorie Intake vs. Burned Calories in a simple, unified view.
- Smart Reminders: Intelligent notifications remind you to log meals (Breakfast, Lunch, Dinner) or workouts only if you haven't already.
- Privacy-First Sync: Securely sync your data to a Google Sheet in your personal Drive. Using the restricted
drive.filescope, Healthio only interacts with its own files, keeping the rest of your Drive completely private. - Health Connect Integration: Seamlessly import workouts, total daily active calories, and Weight data from wearables and smart scales (like Withings) via Google Health Connect.
- Weight Tracking: Monitor your weight trends with a clean time-series chart. Log weight manually or sync automatically from smart devices. Supports both kg and lbs units.
- Workout Logging: Log workouts manually or sync to keep track of your active energy burn.
- 16 KB Device Support: Fully optimized for next-generation Android devices with 16 KB page size support.
- Modernized UI: High-performance, edge-to-edge interface with Material 3 components and optimized system-wide themes.
- Historical Stats: Visualize your progress with beautiful charts for Fasting consistency, Workout frequency, Nutrition trends, and Weight history over the Week, Month, and Year.

Healthio is built on the principle of least privilege.
- Restricted Data Access: The app uses the
https://www.googleapis.com/auth/drive.filescope, meaning it can only access files it creates or that you explicitly open with it. It has zero visibility into your other personal Google Drive documents. - Data Sovereignty: Your data stays in your personal Google Drive account in raw spreadsheet format. You own it, and you can export or delete it at any time.
- Local-First: All health data is stored locally in a Room database before being synced, ensuring the app remains functional even offline.
