Educators and teachers can suggest new applications.
An App Store is a key element of this strategy.
In a partnership with Aptoide (www.aptoide.com) , Safe Explorers provides a ready-to-use App Store where you can manage every aspect of the store:  choosing the desired apps from a set of 180.000 different Android Apps, manage the applications workflow (adding new apps, removing,...) and check the statistics of the usage.
