Could this be the cutest app ever? Quite possibly. Illustrated by Il Sung Na, the App of Sleep is a sweet story of an owl who explores the sleeping habits of various animals before returning to his tree at sunrise. You touch the owl to turn the page and touch the animals to send them to sleep. But the twist is that there’s also an alarm clock that you can record your own wake-up message for and (my favourite bit) the Hush Little Owl sleep aid – images of the snoozing owl dreaming, accompanied by soothing music to help your little one drift off gently (you can also set a time for it to turn off). Just lovely. £2.49, the App Store.
