We’ve not tried this app yet and have not tried an app that does sleep analysis via sound recording – it “sounds” interesting, but we’ll need to see if there’s anything useful. So far the sleep trackers we’ve used were physical devices in some way attached to a pillow or the bed itself. If sound recording really does work in some way, you could imagine Amazon’s Alexa with some additional sensors for environment (humidity, light, air quality) also being able to be an AI-like sleep helper. We’ll try this app out later and see how it goes, we’ll report back here of course 🙂
