a fun & simple sleep trainer for your toddler

TwinClock, TwinClock, Little Star
Save your sleep while your toddler stays in bed.


TwinClock is a simple sleep trainer app for your toddler. Just wait for the sun to show up before getting out of the bed!


All you set is the wake-up time and an optional unlock code, and then leave it to TwinClock to make it fun for your little one to sleep longer. The funny stars will disappear one by one until the big bright smiley sun comes up.


With a reward program based on your child’s ability to wait for the sun before getting out of the bed, you can expect great results after a week and sleep longer in the mornings.
