Hands down the best

Its amazing how far ahead of the field this app is. Was majorly disappointed when it didnt work with my new phone and I had to settle with another mediocre app. Since I wake up earlier than my wife but stay in bed working, the ability to run in the background while in other apps is priceless. Seems like a simple feature that no one else has! This update is a nice Christmas gift. Thanks, guys!
