I would like to use the screen time of My 5 yr old boy more effectively rather than watching YouTube.. He has just completed Jr. Kg.

Any recommendations of educational android apps exploring number skills, phonics, sight words etc.?

Chu chu tv is a big hit with rhymes. I love Disney jr. for the interactive  learning. Any other Preetjyot Kaur(mylittlemuffin) , Charu Sareen Gujjal Tag Fwd

But these are YouTube channels? I'm looking for educational games/apps
