ONDA← All tools

See what your Apple Watch already recorded

A free tool that reads two weeks of your own Apple Health — resting pulse, heart-rate variability and breathing rate — and shows you the range, not a single number. Everything is read on your iPhone; the figures are never sent to us.

You add it once, then tap it once — that is the whole thing. It reads your watch on your iPhone, and the numbers never leave it: they ride back in the part of the address your browser keeps to itself.

Your figures stay on your device. We never receive them, and this page carries no analytics.
