The original Qardio App no longer works, and requires us to log in to read our blood pressure readings, when the company has shut down their servers. This tool stops you from turning your trusty Qardio Blood Pressure Monitor to e-waste. No need to sign up to take readings, no need to provide a company with your data. It is all stored on your phone, and you can also save readings to the Health App.
LibreArm
This app allows you to track your blood pressure readings from a compatible monitor directly to your iPhone. It prioritizes privacy by keeping all your data offline and locally stored, with optional integration into Apple Health. Enjoy a simple, ad-free experience without accounts or subscriptions.
- Connects to QardioArm via Bluetooth
- Saves readings to Apple Health
- Offline data storage
- Simple, clean interface
- Open-source project
