Aside from the motion tracking, it’s able to vibrate very faintly at T minus 10 minutes, 7, 5, 2, 2, 1, 0.5 minute from waking up. Then vibrates gradually to wake me up gently.
It also automatically tells you when you should set your wake up time to optimize sleep cycle.
To reduce my sleep inertia I’ve created an app for my 25$ micropython smart watch (Pinetime from Pine64). Here’s the link: https://github.com/thiswillbeyourgithub/sleep_tracker_pinetime_wasp-os

I think it works very well but I’m very biased.
