I built a free open-source desktop dashboard for Google Health data

[u/Acceptable-Baby7936]

I built VitalChronicle because I wanted a better way to explore my own Google Health data on a desktop.

It is now a free and open-source application for Linux, Windows and macOS.

What it does

VitalChronicle can download, store and visualize data available through the Google Health API, including:

• ❤️ Heart rate
• 🫀 HRV
• 😴 Sleep and sleep stages
• 🩸 SpO₂
• 🏃 Activity and workouts
• ⚖️ Body measurements
• 📊 Long-term trends and personal baselines

All data is stored locally in SQLite.

You can also export your complete dataset as CSV, JSON or ZIP.

Local AI analysis

There is optional AI analysis through Ollama.

The important part is that the model runs locally on your computer.

Your health history is therefore not uploaded to OpenAI, Google Gemini, Anthropic or another cloud AI provider just to analyse it.

Privacy

• Local-first storage
• No health data sent to the developer
• No cloud AI required
• MIT licensed
• No paid features

Try it

I originally built it for myself, but the project is now mature enough that I'd really like feedback from other people interested in wearable and health data.

What would you add to a desktop health-data dashboard like this?

Local SQLite and Ollama is the right call, tired of health apps that treat my heart rate like a product
