The app has been designated by the Latgalian cultural movement "Volūda" ("Language").
Vasals! app provides four games aimed at the improvement of Latgalian vocabulary and grammar, as well as learning about places and music of Latgale.
Concern is often voiced in the public space about insufficient support and promotion of the language, so the app comes just in time to help 'čiuļi' [non-Latgalian Latvians] and others learn more about it.
The app is available for Android devices on Google Play.
