Very effective

This app is efficient for when I really need to make sure Im awake in mornings. I put the "shake to wake" mode on high and play an upbeat playlist on YouTube or Spotify and Im up within a minute or two. I usually have to have at least 20 alarms with the he regular alarms on my iPhone but this does the trick just fine.
I kind of wish the app explained the different modes though, I was lost for a bit.
