The Volirium P1’s software is newly designed and developed, focusing on ease-of-use and manual-free operation. Its user user interface makes use of the concepts found on other mobile devices, like smartphones and tablets. This way you will feel immediately at home and know how to operate the P1.

Development is still ongoing, we continue adding features to the P1, and making it even easier to operate. You can help with this, by providing feedback, or even joining the development team. Contact us if you are interested.

Automatic updates
