Pulse Bridge

Pulse Bridge is an open-source iPhone app that keeps the Pulse One (Makina) fitness band useful after its maker shut down. It talks to the band directly over Bluetooth, keeps the data on the phone and writes it to Apple Health, with no account, no cloud and no third-party services.

## What it does

- Syncs heart rate, HRV, blood oxygen, steps, distance, sleep stages and workouts from the band
- Writes everything to Apple Health, without duplicates
- Readiness score each morning from HRV, resting heart rate, sleep, activity and temperature
- Runs, walks and rides with phone GPS and band heart rate, with zone alerts on the band
- Live Activity on the Lock Screen and in the Dynamic Island
- A daily challenge (push-ups, squats) with streaks and a short text to share with friends
- English and Romanian
- The commands that reset or wipe the band can’t be built by the code at all
