Hybrid OSN is a hybrid Twitter client for Android. While Twitter can be used as usual, data can also be securely exchanged with other users via a P2P network. Therefore Twitter is not able to analyse, sell or censor this data.

Hybrid OSN was developed by Carsten Porth under the supervision of Aidmar Wainakh and Jörg Daubert as part of a master thesis at TU Darmstadt. It is a prototype which was created as proof of concept.
