Very rudimentary apps, supporting only part of functions provided by P12 band: ECG, steps counting ( calories, distance), hearth beats, blood pressure, sleep quality. No oxygen level, no breath frequency are supported by app ( despite provided by the P12 band). The messaging (5 last messages) are working fine. The blood pressure is a joke! Fitness function ( there are 3 kind of fitness) in fact are the same, still providing useful information. In fitness mode the heart beat function surprisingly working not bad!Still , the P12 manufacturer should push the app author significantly improve the app to get visibility on the market. P12 band has good potential that is unused by 90% just because very week app.

I agree with Eddie comments. The Blood pressure shows what ever you set in the app under personal information. The question is, does the measurements are real.?

Was working then stopped I am thinking from the last apple upgrade a few days ago ( watch no longer shows up in BT list) reset/reinstalled no luck also never able to create a account, used the skip option

This is a terrible app and fitness watch. App doesn’t sync to watch, has me log in then won’t let me go to another part of the the app unless I log in again. Except this time it doesn’t recognize your user name, and you’re stuck. Heart beat doesn’t work, neither does any of the other promised functions. A phenomenal wast of my money and time. Into the trash it’s going.
