I'm looking for an alarm clock that also has a sleep timer built in that will automatically put my Mac to sleep after so many minutes or a set time. I've been going to sleep listening to some Youtube clips at night. I was using a widget to turn my Macbook off after a set amount of minutes, but after reinstalling SL, I'm looking for both an alarm clock and a timer. If possible, I'd like to find one in the App Store. I kind of like how it keeps everything together. Also, free or inexpensive is best.
