Autosleep does both these things and has a non-subscription based payment.
Or at least almost, their alarm wakes you when you’re in your lightest sleep stage possible during a set period of time and before your set wake-up time.
Example: I have to get up before 6:45 in the morning and I’m fine with waking up within 30 minutes before that, so between 6:15 and 6:45 Autosleep will try to start tapping my wrist gently by vibrations when it figures I’m in my lightest sleep stage during these 30 minutes.
I usually combine this alarm with a normal backup 5 minutes later and also use my ceiling lights as a gradual wake-up light. Most of the time I feel like I’ve woken up by myself.
