Smart alarm clock + Bedtime reminder that wakes you in the lightest sleep cycle using Apple Watch. Using Haptics to wake you so that it is gentle on you and it does not disturb your partner.
The fact that I can wake up with out waking up my other two house mates is great. The watch taps me gently and increases until I start moving around, to which it then fades away and if I don't move again for a few minutes it comes back. It's a really gentle and effective way of nudging you awake without getting in the habit of hitting snooze.
The watch and app graphics are nice and dark. I point this out because too many sleep apps are way too bright.
I can start the alarm from my watch, my phone can be plugged in and away.
I would like to see some refinements in the app UI. There are a lot of great features but they're hidden behind strange buttons and tucked away deep within menus. A walk-through wizard to set up the alarm and an easy to update dashboard when you first get to the app would be amazing.
Silent but effective, auto-snooze and auto-off based on motion, dark graphics, snore detection and anti-snore
Need to charge before/after (worth the data though), the UI on the app is a little cluttered, but not impossible
