I have released version 2.1 of Wakeify. It's an Android app that allows you to wake up to Spotify tracks. You can download it here for free: https://play.google.com/store/apps/details?id=com.matthewmitchell.wakeify
The app uses the Spotify application installed on your device to play music at the time you specify. It features a gradual volume ramping feature, a snooze function and repeats on certain days of the week.
I welcome any feeback and can answer any questions that people have. If anyone experiences any issues please let me know.
