Questions

Good to know.

Do you only build for Android?

Google Play is our speciality, so every project is built Android-first. Many of our engines and frameworks can also target iOS later if you need it.

Who owns the code and the Play Store listing?

You do. The app is published under your own Google Play developer account and the source code is handed over at the end of the project.

How long does it take to publish a game or app?

A focused casual game or utility app typically takes 6 to 12 weeks from kick-off to Google Play launch, depending on scope.

Can you take over an existing app?

Yes. We start with a short audit of the code, store listing and Play Console vitals, then propose a plan to stabilise and improve it.

Do you work in French and English?

Oui ! Our team is based in Paris and works with clients in both French and English.
