We are Olivier Castille, a developer, and Valentin Gall, a designer.
Together we are DoubleMoon. A french creative studio. We make app. Cool app.
We started in 2011 with a simple app. A sales calculator. For fun. And for test iOS’ possibility. We made it in two days.
330.000 download, number 1 on the AppStore, app of the week by Le Monde, some interviews and V4.0 today.
Get the App in the AppStore | Get the App in the Google Play.
We started again in 2012 with a most ambitious app. The first real digital book. Where children can create their own stories. A book of which you are the hero. Or the bad guy. We called that Il était des fois.
Congratulated for its design, promoted in the press, cited as an example, relayed on TV and radio, guest at TED conference, performed in festival, used in hospitals, praised by speech therapists, invited in library, taught at school, listed among classics, exhibited in gallery and even recommended by the French US Embassy!
Wow. That’s pretty amazing.

We didn’t stop there. We have taken the concept Il était des fois even further. By creating educational workshops and didactic activities. With paper, wood and threads! Today we work in museums and cultural spaces.
See some photo here, and here, and here.
We have no idea for our third application yet. But it will come.
Outside, we love to play basketball and eat pizza. Not necessarily at the same time.
Please don’t hesitate to contact us if you have any questions.
Thanks for reading. Best.
Valentin & Olivier
