British company Hopster describes its app as “educational kids’ TV”. What that means is a collection of familiar cartoons and shows including the likes of Sesame Street, Bob the Builder, Thomas the Tank Engine, Fireman Sam and Pingu, accompanied by fun learning games on topics such as maths and phonics. It will even remind kids not to binge on too many episodes in a row. Free - Also available on Android - https://play.google.com/store/apps/details?id=tv.platomedia.hopster
