Alltock is a clock for procrastinators. It varies from on-time to 15 minutes ahead, but does not tell you how far ahead it is. Will you risk being 10 minutes late because you think it’s showing 10 minutes early? Nope. That’s why it works!!The Alltock clock does not alter the built-in Android clock, nor does it affect the time seen and used by other apps. Alltock alarms only sound when you’re on the main Alltock screen. They do not override the built-in Android clock alarms.Alltock makes a great bedside alarm clock on your phone or tablet. Mix with your favorite Live Wallpaper for the ultimate custom clock!
