Show HN: Hamilton – a no-internet Android health dashboard, named after my dog

Hamilton is a privacy-focused Android health dashboard app that aggregates health metrics from multiple devices and apps (Garmin, Withings, Fitbit, Samsung Health, etc.) through Android's Health Connect platform, all while keeping data entirely on the user's phone with zero internet permissions. Named after the developer's dog, the app eliminates the need to switch between multiple health apps by displaying steps, weight, heart rate, sleep, and other metrics in a single interface, while intelligently avoiding double-counting data from multiple sources. The app prioritizes user privacy by design—it cannot connect to the internet and requires no account or data sharing.
