The sleep feature used to drive me nuts - it was inconsistent.

I’ve found that it works better since I turned off ‘sleep schedule’ and started to manually turn on ‘sleep focus’ when I go to bed.

Still haven’t upgraded. Would love the Snoopy faces, but happy with the way things work on the old OS.

Use it for elapsed time and HR.

Distance won’t be reliable due to GPS issues amongst the tall buildings and not running the tangents perfectly.

If you have a goal time in mind, print out a pace chart and carry it. You can compare your elapsed time to the pace chart when you run past various mile markers.
