Apps for Common Entrance revision?

[Squeezle]

Looking for suggestions for (android) apps to help with CE revision. So far I know about
French - duolingo
Latin - quizlet

What else do your children use? Can you tell I'm trying to gently encourage a child towards revision?!

We are just doing textbook notes and past papers, would love to know if there is an app but never seen one - good luck! Dreading the Easter revision

I looked at the link but can't see anything specific to Common entrance.. Its all pretests and 11 plus?
