Development for a mobile future


We do professional software engineering and develop apps, mainly for iOS and Android, but also for newer platforms such as tvOS, watchOS and Android Auto. Thereby we use agile project methodologies. The apps communicate with vehicles made by Audi, Porsche and Bentley, enabling access to various functions, such as the entertainment system, server-based backend services and Bluetooth connections.

We offer app development completely from Germany, more precisely „Made in Bavaria” – with residence in „Silicon Schwabing“, the technology centre of Munich.

Quartett mobile was founded in 2011 in Munich by Albert Feller (†) and Leon v. Tippelskirch, both graduates of the Technical University of Munich. Audi Electronics Venture (AEV) is accompanying Quartett mobile since the very beginning. One of the first projects with AEV has been the Audi MMI Connect App.

You can reach us via emailTwitter and our contact page. Or just drop by the office.



Quartett mobile is more than a usual company. Here you will find a flat hierarchy, small teams and a geeky and friendly atmosphere with people who know what they are doing.

Munich, the cozy million-village in the south of Germany, is a perfect starting point for our test rides, and a place where you can live outstandingly. Whether you are barbecuing with the Quartett mobile team on the roof terrace, visiting various after work events, Movie Nights or cultural exhibitions, or taking part in the Blade Night - there is always something going on.

We are probably the biggest Club Mate consumer in northern Munich, and we offer opportunities for not only seeing but also hands-on playing with the newest developments of the tech world, going to conferences, and celebrating achievements. 

We are always looking for qualified app developers and talents. You can join us either as a working student or with a longtime experience in app development.
