Live GitHub The write-up

I reverse-engineered a HidrateSpark bottle so changing the LED didn't cost $5/month. The app talks to the bottle straight from Chrome over Web Bluetooth, no account or subscription involved.

The hydro.sh landing page — a blue gradient panel that reads 'Track your hydration, effortlessly' next to Get Started and Go to Dashboard buttons — The landing page. Everything runs in the browser.
