I am

Martin Stemmle

, Freelancer, Indi-Developer and Co-Founder based in Berlin.

I mostly focus on iOS and Mac apps. However, I am open to all sorts of cool new stuff.

I like to divide my work into three scopes

Focus is always changing back and forth from time to time.


As a freelancer I focus on native iOS development, however I am also open to new opportunities. Check out my skills and tools I am familiar with as well as the apps & projects I have been part of the team.

Get in touch if you are looking for developers for your next awesome project.


I have always enjoyed building things. By learning how to write software and build apps in particular I have opened up a whole new world for that.

For my own projects I mostly look for ideas that can be build rather easily by still creating something useful (and eventually even valuable). Furthermore the projects have to be maintainable as a side project on my own.

However, I am also open to join or contribute to (open source) projects if they are appealing to me. That being said, feel free to get in touch about any projects.


CINEPASS is the easiest way to get your movie tickets in Germany.

Enjoying building things also lead me to start an own business. With Cinery we started off by buliding a state of the art iPhone app for cinema showtimes and ticketing. After merging with CINEPASS we now support all major platforms with fully native apps for iOS and Android and a responsive Website  for every other device.
