Hi there. At Tizzy Labs, you can be sure of one thing...we always have your kids best interests at heart.
We are 2 developers who have 6 kids between the two of us, and we only create games that we would want our kids playing and learning from.
Our apps made for children will never have Ads rotating through them as a way to make extra money. I cannot tell you how many times I have been frustrated with a good game that had horrible ads in it, that were very inappropriate for my kids eyes and ears.
We want you, the parents, to know where we are coming from. We're regular people, just like you, trying to make games for our kids to play. And we hope you will let your kids enjoy them too. :-)
