About us

appfour GmbH is a privately held startup company, founded by Hans Kratz and Dennis Strein, PhD. We are located in Karlsruhe, Germany. We love devices, we have many of them. However the process of sharing data between devices seemed broken to us. The more often you switch between devices the more painful it gets. We wanted something simple, fast, secure and with guaranteed privacy to solve this. That's why we built Scatter.

We are also the creators of the popular App AIDE - Android IDE
