I'd say the age varies. My daughter started at two. Just a few minutes here and there, mainly when she wanted our phones, but within a week was figuring it out. She's 3 now and there isn't one activity she can't do. Don't just throw your kids in front of a screen on day, but an hour of learning time helps you, helps them develop skills, and just helps them grow. Be careful of what games you let them play, but free learning games like this, that actually teach are fantastic!

my one critique is there needs to be less distractive noises, horns, sound fx, and fix the voice that gives the directions twice. It only needs to say it once but it'll repeat the directions 1 second after it just said it. All these things are distracting to students and it makes it difficult to focus, especially for a toddler. Simple is better when it comes to noise and animation so the child can focus in what's being asked of them. It even triggers my ADD.. too much noise and distractions.

This is an absolute wonderful app for my young child, it has large animation to keep eyes from strain, great with no ads for free..I love how you can also select a mode for the games which you want to randomly appear for your child to play , and they not only stay on the same game, it switches throughout the games to keep from boredom for the child and it keeps it fun, I will keep and will continue to look for more apps under you guys, thank you and thank you again for the no ads without a cost.
