This app solves the problem of young children (preschools / toddlers) getting out of bed to early and waking their parents.

Since most of the toddlers / preschools are not able to read a clock, but are awake early they want to get out of bed too early.

This app colors the background red when the must sleep. Just before (you can set the time) they are allowed to go out of bed, the display turn slowly more yellow (progress bar) so the child knows it’s almost time to get out of bed and there is no need to go to sleep anymore. Finally the screen turns all green, indicating that the child is allowed to go out of his bed.

This is not an alarm clock, since it silently displays time and accompanied color.
