My daughters love the Toca Boca apps—especially Robot Lab. Ingrid Simone’s article on their approach to gender is great. From Gender in Play: How Toca Boca Creates Apps for All Kids:

Toys have a large impact on how kids play together and relate to other kids. But kids of today are fostered into watching different shows and playing with different toys according to their gender.

We know that when a toy reaches a child a choice has already been made for them, someone has picked a blue or pink toy, an action figure or a doll. We believe this is limiting to kids, not to be able to decide on your own what your interests are, and that gender-targeted toys create an unnecessary barrier between girls and boys. And we believe that girls and boys, brothers and sisters want to play together!

And on the redesign of Robot Lab specifically:

Since the robot theme has historically been so targeted towards boys, we felt like we, as many before us, had somehow fallen in the trap of using conventional “boyish” colors, shapes and attributes. And we really wanted to see if we could make the app more appealing to both boys and girls.
