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.
