While I believe that AutoWake and HeartWatch are excellent apps (and have reviewed them as such), I cannot say the same for AutoWake.
You can set AutoWake up to automatically wake you at a certain time for each day of the week. In my case I have it set to wake me at 7:00 Mon-Fri.
You can also override this behavior as needed, i.e. I disable the alarm if I am taking a day off work or have a holiday.
Its greatest advantage IMHO is that it is supposed to find a time when you are sleeping lightly near to your set alarm time and then tap your wrist to wake you up.
It more or less works most of the time. And when it works it works very well.
I have AutoWake added as a complication on my primary watch face (my ONLY watch face) as required and my phone sits charging on the end table beside my bed so there should be no reason for failure.
But the alarm has failed to go off in the morning 4 times over the past two months. This might not seem terrible, but if you need to catch a plane the next morning – which I sometimes do – I don’t want my alarm to be flakey.
What usually, but not always, happens is that the alarm will go off later in the morning, 9:40 and 10:20 AM are two times that I recall specifically.
This morning it just didn’t go off at all.
I will be deleting this app and falling back to the Apple Watch’s built in alarm.
