Pocket - Urbit for iOS
Urbit is a reimagining of what an OS can be; built around the concept of a peer-to-peer network. Users have “ships” that can talk to each other in a federated manner. Previously, the most common way for users to do this was through a web-based product called Landscape.
The Pocket app allowed users to sign-in to their ships and load all of ther DMs and group chats. They could also create new DMs and group chats with people they were in shared groups with.
The app was sunset in Fall 2023.
