How to read your RingConn HRV

We have not verified from RingConn’s own pages which HRV formula or time window it uses, so we do not label it here.

Compare like with like: the same device, at the same time of night, over several weeks.

HRV type: Not confirmed from official pages.

Compare a night with your own usual range over the last weeks, not with another person or another device. A single low night is most often a reaction to something specific — a short night, alcohol, an infection, stress or hard training. Several days below your range together with a higher resting heart rate and feeling unwell are a reason to rest.

Scores such as Readiness, Recovery, Nightly Recharge or HRV Status are each maker’s own algorithm. Two devices on the same night can show different HRV numbers because they measure at different times and with different formulas; neither is “wrong”.

RingConn does not offer a public developer API that we could find, so a direct connection is not possible.

Through Apple Health

We have not confirmed that RingConn writes HRV to Apple Health, so we do not promise that your RingConn HRV will appear in ONDA. If your device is not Apple Watch, ONDA can still measure your pulse with the iPhone camera, along with a breathing-rate estimate. The camera gives pulse, not HRV.
