This app helps toddlers, preschoolers and young children sleeping longer. This user friendly bedtime trainer gives your child a visual indication whether it is time to get up or to stay in bed.

As long as the moon picture is lit, your kid knows it has to sleep a while longer. In the morning, at a time chosen by mom and dad, the moon switches to a picture of the sun: it's okay to get up! Result: a better night's sleep for the little one and, equally important, his/her parents.

The app is inspired on bedtime trainers such as the Kid'Sleep device series. But why would you buy an expensive device if you can use a(n old) smartphone instead? The app is designed to be compatible with older Android versions, so it will work on your deprecated device without any problem.
