In a statement on their app the creator said:
Dear all,
It has always been a great pleasure to work on this project. However, it is time to say goodbye. I am going to shut down Terrarium TV, forever. I know this day will come eventually. I know it would be hard to let go. But it is really time for me to move on to other projects.
Thank you for all your support through the years thanks to all Terrarium TV supporters and communities. Thank you, Nic, and all the people around the world who care about this project.
Please note that you will not be able to open the Terrarium TV app after the end of September as the app will close itself automatically. Please DO NOT try to click the Update button because it will not download any new version of the app.

Thank you and Farewell.
