Hi there!

MaraTick


A simple todo list maker for any Blackberry with OS 4.0 or higher.
Version: 1.0.8. Features include: MaraTick was written by me, to help reduce paper waste. It is named after my daughter Mara, who cares about mother earth more than I do. Therefore, more people would use it, better it will serve it's original purpose. Special thanks go to her, who also helped me to find icons for todo lists.
Please send any suggestions, recommendations and bug reports to my email: regsurenb@gmail.com. I am also interested in any new BB application ideas that will help to reduce the paper use.
