- QardioArm devices became unusable when Qardio, Inc. went bankrupt and removed their app.
- LibreArm was created to revive QardioArm devices by reverse-engineering the Bluetooth protocol.
- The project involved sniffing Bluetooth services, decoding byte arrays, and building a privacy-focused iOS app.
- The app integrates with Apple Health and ensures only complete readings are saved.
- App Store approval was challenging due to medical device regulations, but it was eventually accepted as a wellness app.
- LibreArm is open-source, ensuring community control and resilience against removal from the App Store.
- The project highlights the importance of open-source solutions to keep hardware functional after company closures.
