I'm the developer of TaskUnifier.
The first versions of TaskUnifier were released in 2010.
I developed it for years, but I had to stop in January 2015 for personal reasons.
In April 2019, I decided to re-work on TaskUnifier, and I developed a completely new application, from scratch, with newer technologies.
Since September, TaskUnifier is available to the public and is under active development. It allows you to synchronize your tasks with Toodledo and is available on Windows, Mac and Linux
