Clovering covers your everyday biometrics; an Apple Watch adds a few features that need extra hardware.
What Clovering is
Clovering reads the health data your COLMI ring has already recorded and writes it to Apple Health on your device. It's a bridge, not a sensor: your ring collects the data, and Clovering moves it to Health without anything passing through a cloud or account.
Once it's in Apple Health, any HealthKit-compatible app can read it, including viewers like Bevel, so you can explore it in the tools you already use.
How it works
-
Pair your ring
Connect your COLMI ring to Clovering over Bluetooth in a couple of taps.
-
Read on-device
Clovering pulls your latest readings straight from the ring. Nothing leaves your phone.
-
Sync to Apple Health
Grant the metrics you want and they land in HealthKit, ready for every app you already trust.
Privacy isn't a setting. It's the architecture.
Most wearables route your personal biometric data through someone else's cloud. Clovering has no cloud. We can't see your data, by design.
COLMI ring Your ring's sensors capture biometrics like heart rate and sleep.
Your iPhone Clovering pulls and caches the data from your ring over Bluetooth.
Apple Health Your readings are written and permanently stored in HealthKit, where any HealthKit-compatible app can read them.
No cloud
Choosing a ring
Clovering is built and tested against the COLMI R02. Other rings on the same QRing app and Bluetooth protocol should work the same way — but the R02 is the only model we've fully verified.
R03 · R06
Should workClose siblings of the R02 on the same protocol, so they should behave the same. We haven't verified each one individually.
R09 · R10
Temp coming soonAdd a skin-temperature sensor. Everyday metrics should sync like the R02; temperature support is still untested and on the way.
Rule of thumb: if a ring's listing tells you to pair it with the QRing app, it likely speaks the same protocol — including many rebranded look-alikes. COLMI rings are sold on Amazon and on AliExpress, which is usually around half the price (with longer shipping).
