Meet FLX Apps

Hi. My name is Felix.

I create Android Apps and have major skills in Web Development.

Having started as a school student, I now have over nine years experience in developing and publishing my own Android apps. My most popular app had over two million downloads before it had to be discontinued. AlcoTrack, the project I am currently working on the most, has a growing international userbase and been translated by the community into 12 languages. I love coffee, books and cinema.

Feel free to contact me for business inquiries or any further questions.

DetoxDroid is an open-source non-profit project in the spirit of Humane Technology. In times where every app on our phone competes for our attention (with even games reminding us to play if we did not open them for a time), DetoxDroid assists the user in getting rid of attention-grabbing and manipulative features. The mission: Use your phone rather than letting your phone use you.
