So I took a chance and tried this app bc I love spotify (I have a premium account) and Im tired of waking up to my iTunes music.
It works great, its simple. Yes you will want to leave your phone plugged in all night (dont you do that regardless?), but just lay it facedown with the app open and you will be good. Its the same exact function with the sleep cycle app, where you leave it facedown, app open, under the covers all night. So dont let the Debbie downers dissuade you. I used this last night and woke up pleased (Bill Evans woke me up - so nice) :)
