Who we are

The development studio MasterApp was established in the spring of 2014 as the software division of Cloud4Data. The background for development and testing is provided by our own MasterDC datacenters. We create in-house apps as well as custom apps for clients. We love helping others with our work.

A team of experienced developers is complemented by internal graphic designers, testers and marketing, UX, and other specialists. All teams work very closely together. While developers work on the code, marketers supply localizations, product descriptions and optimizing keywords for the App Store, Google Play, or Microsoft store. We can also help you with app accessibility for the handicaped.

Web projects as well as mobile apps
