I am working as an IT teacher in Spain for several years. Before that, I was some years working in the private industry as a software engineer.
Some time ago, I created an app called “Apolo“, for the old PDAs with Windows Mobille (published on Observatorio Tecnológio del Ministerio de Educación y Ciencia).
Now, in my spare time I am developing a new version of “Apolo” for Android called “Teacher Gradebook“, I use it in my daily lessons.
I do not get any external funds. I get funded with the app’s adverts and with users that want to become premium.
