MyRunning ap best running App. Have had problems running this on my Prime 2 A10 watch with Android Energy Management error. However used the app with my new Prime S A9 for three months without a problem. This is a cheap alternative and also now includes the health apps as a bonus. My original prime never worked properly with the blood pressure monitor. Hope this helps those with an alternative for this excellent app.
If you install the internatiinal FAW firmware on your P2 you will find it will now work perfectly
