Which apps can you recommend for 5yr and 7yr old

[redbike]

Hi. I am looking to install some FUN educational apps for a 5yr and a 7yr old. I have found a music app called Rhythm Rooms which has gone done well, but would appreciate your views on other app you have found useful for learning. THANKS.

Squeebles? - I think that's what it's called - it's a great multiplication and maths app for that age.
