I have a sleep app and wear the watch at night. The iPhone 6 has the ECG app and SpO2 app. I have played around with the ECG and SpO2 and the information interesting but I have not found any useful training / living benefit to apply to making any changes. Wrist motion and watch band tightness seem to impact accuracy. N=1 in my study.
Have you been using the heart rate variability function? The numbers I generate are weird, and I'm going to ask my cardiologist about utility/accuracy. Going to ask her about use of the EKG too. The SpO2 seems to work OK, but I don't really need it much. I may use it for making sure that the pulse/ox meter is working properly when we have guests visit (we live at over 7,500' and I have a pulse/ox meter for their use in the spare bedroom) and for search & rescue subjects I run into.
