My name is Ole René Petersen. I am Danish, living outside Copenhagen, Denmark.


I have designed and coded the apps you find on this site.


Friends and family are a great help making the apps. Here are a few of them:

  • Soren Kjaer Nielsen
  • Lise and Andy Taylor-Vebel, UK
  • Shira Sand, USA
  • Our daughter Linda, who learned reading and writing with the program, which is the foundation of the apps here.
  • Ingrid, my very patient wife.


Many thanks to all of you.
