Goals, in general

I'm currently seeking to subsidize the app development I do for Sailfish, an alternate Mobile operating system. I'd like to be able to also make that work available on Ubports and, eventually, Android. I'm responsible for maintaining more than 2o apps at the moment.

All apps I build are released under the GPLv2/3 (most), BSD 4 Clause or similar licenses.


I work on a wide variety of apps. Perhaps too, broad a swath!

  • Tidings an RSS client (with support for playing media)
  • Several Paint & drawing related apps
  • Two video / animation related apps
  • A client for the German Weather service (Deutscher Wetter Dientst)
  • A reboot of Fahrplan, a public transportation app using backends in numerous countries.

Some of the costs I'd like to defray include Server hosting, a decent build machine and an arm 32 bit test device. Although much can be done with freely available build servers, it's less time consuming to have a fast build machines and test devices for every target hardware platform.

I also do hardware development but am not currently seeking to fund it. I have enough material for on-going prototyping and will list it here when it become appropriate.
