OsmAnd has always been about putting you in control. Our original A* routing engine, configurable via routing.xml, offered immense power. You could define intricate profiles, avoid specific road types, and truly personalize your journey. With maps optimized for minimal storage (the entire planet's car data for our new HH-routing is around a mere 800MB!), OsmAnd was a lean, mean navigating machine.
Setting up your actual Sleep Routine takes a little more time and intention. A Dreamie Sleep Routine consists of multiple steps, which you can use all, some or none of for your custom routine. Those include the Bedtime Cue, which lets you know it's the time to start getting ready for bed (you designate this time); the Wind Down, or the sounds you'll fall asleep to; and the Noise Mask, the sounds that keep you asleep. If you wake up in the middle of the night, there's a Back To Sleep option too.
