Also also, is anyone familiar with the Sleep Cycle app? It uses the microphone or accelerometer to tell if you're moving around in bed and uses that to figure out when, within a 30 minute period, to start gently waking you up from a shallow sleep, to avoid jolting you awake in the middle of a REM cycle.
Is there a FOSS and privacy-respecting alternative to this, or am I just going to have to get it from Aurora and install it without network permissions?
