Annoying prompt to upgrade

There are a lot of these sleep cycle apps in iTunes. Im deleting this one solely because that annoying upgrade thing pops up everytime you open the app.
Within minutes, I found two more apps that DONT do that, and have way cooler setups (in my opinion :)
3 stars because I didnt actually try the alarm clock.
