Withings Aura is a pricey but advanced alarm clock that uses timed, programmable LED lighting to simulate both sunrise and sunset for a good night’s sleep. It also has environment sensors for tracking room temperature, light and sound levels.
While this by itself sounds good enough to begin with, there is also an optional REM sensor for keeping tabs on movement to track your sleep cycle but keep in mind that many wearables such as the Up band already do this as well as tracking steps.
Bedtime just got even more relaxing now that Withings has just announced a partnership with Spotify to pull in soothing playlists to accompany light levels; both light and sound fade out on a timed programme as you fall asleep, or you can have perky tunes to build up to a new day.
