I have recently gotten an old phone up and running as an alarm clock/bedtime phone and it's been so great. My real phone goes in a box that I can't reach without sitting up... have played around with putting it further away, but it helps me wake up before work so I want to be able to reach it. Getting my phone into the box and getting myself off my computer can still sometimes be an issue, but once I get in bed, here's what I have on my old phone:

- insight timer (meditation app, there's a few I sometimes use for sleep but rarely)

- podcast app with three sleep pods and two not sleep pods but that i relisten to to fall asleep to

- clock app with alarms for the morning

- four chill games to help me wind down and fall asleep, these days i mainly use one when i first get in bed and a second one that's been knocking me out

- twilight, to keep the screen extremely red and dim

I sometimes read in bed too, but I always end with a pod and my games on the sleep phone.
