Think of an App so simple that can be used by a baby of 8 months!
My First Tap is exactly this.
We were looking for an App for our little Luca of 8 months, but on the App Store we didn't find an App that satisfied our needs, so we created one!
And it's so simple that it's enough a TAP with 1,2,3,4  10 fingers in any part of the screen!
Maybe you have an iPad and every time your child arrives near the device you realize not to have an App suitable for him!
And it's a pity! The iPad is so simple to use and friendly!
