Pretty good and lots of Interactivity

I like this app, but what would make it supreme is if you had the capability to take a Nap or Power Nap with just the watch. Any sleep functionality requires the phone to be activated in some manner, yet the watch does most of the heavy lifting calculation and is well suited to play audio and vibrate to wake you up. I hope they can update this to be able to use just the watch as an alarm for shorter sleep sessions. I understand that the watch has to analyze the data it captures throughout the night, but why can’t it just do that automatically once you stop the alarm on the phone. I wanted to rate this a 3-star but to be fair I feel it leans a little closer to 4/5 stars, hope this input and suggestions helps the developers in someway?
