Please note: K12 no longer offers the xGerms mobile app. This article refers to an app that was available prior to August 2017.


K12’s xGerms Addition math mobile app was named a Mom’s Choice Silver Award recipient for being “among the best in family-friendly media, products and services.”

The popular app was released in 2014 as an updated version of the original. In the app, students had to master addition facts to defeat a new crowd of mathematic microbes.
