WakeWorker

WakeWorker is an alarm clock that can wake up your computer and then make getting up with your favourite song more pleasant. In the evening, when you go to bed you simply set when you want to get up in the morning and start the countdown. Or you can use the recurring wake-up call and set a specific time for each day to get up. In the morning, WakeWorker automatically turns on your sleepy computer and plays your favorite song (you can even set it to turn the volume up to maximum beforehand).

In order for the app to wake up your computer, you need to enable the so-called wake timers. WW will happily do this for you, just tap the question mark icon (bottom left) and tap the enable WakeTimers button.
