Just to confirm, the app does work with the iPhone 16? Or would you recommend getting a polar strap at this point if one is planning on upgrading?

hello Greg, all good with the 16, I use it as well, with the camera. Normally I use the strap only for the HRV4Biofeedback app or the HRV Logger, as those apps typically require long measurements for which I prefer an external sensor. All good with HRV4Training and the camera for morning spot checks.

Thanks! My ancient iPhone SE is finally on its way out, so I upgraded begrudgingly to the 16e.

I have a clue now: it seems to work in a dark environment but not in daylight. So when waking up and measuring with curtains closed (real dark in my case). Never in daylight?!
