The core of OsmAnd's HH-Routing is an elegant two-level hierarchy built upon "area clusters."
After taking a few days to tweak my choices and figure out what I like best, I've settled into a really nice routine: Aurora Borealis as the Bedtime Cue, an hour of Forest Wind as my Wind Down and a Noise Mask of Brown Noise to play throughout the night. I love how easy it is to set the nighttime routine in motion once it's established. When I hear the Aurora Borealis come on, I start making my preparations for bed. Brush teeth, take meds, lights out and, crucially (I'm trying really hard to be disciplined, here), my phone goes face-down on the nightstand until morning. If I want to stay up late that night and ignore the Bedtime Cue, I can just hit the little stop button on the display. But once I'm ready to actually try to fall asleep, all I need to do is swipe down on the display to initiate the Wind Down, and Forest Wind will start playing.
