Mediathek Hessen is a multimedia app developed by GMM AG in collaboration with the Hessische Landesanstalt für privaten Rundfunk und neue Medien (LPR). The app offers a selection of the latest broadcasts produced and distributed by the partners. It's a unique platform that showcases a mix of non-commercial providers, open channels, and private/commercial broadcasters, highlighting the diversity of the media offerings in Hesse.

The app is recommended for those who want to stay up-to-date with the latest media content in Hesse. However, since the app contains lengthy videos, it's advisable to use it with a high-speed Wi-Fi connection.
