Clovering covers your everyday biometrics; an Apple Watch adds a few features that need extra hardware.

What Clovering is

A simple data bridge: your smart ring does the measuring, Clovering simply moves the readings into Apple Health.

Privacy isn't a setting. It's the architecture.

Most wearables route your personal biometric data through their own cloud. Clovering routes it directly to Apple Health fully on device. We can't see your data, by design.

Your data is yours. Clovering has no servers, no account, and no cloud sync. The app writes your readings straight into Apple Health on your iPhone, with no network connection and nothing sent to us or any third party. Any iCloud sync is Apple's to handle, end-to-end encrypted and under your control.
