The official RabenApp from Klett for primary school.
Raben App belongs to Nussknacker (Nutcracker) series, one that we have had a long history with.
In 2002 we developed educational CD-ROMs for Ernst Klett Verlag in cooperation with Tivola Publishing GmbH. In these CD-ROMs little vampire Freddy helped pupils to learn Mathematics in primary school.
In 2008 these CD-ROMs were re-branded by our company to Klett's own character Rabe (Raven in English) -
Now, Raven comes to App Stores for iOS and Android as RabenApp!
