A first computing device running a particular program is used to identify a second computing device also running the particular program and substantially co-located with the first computing device in a particular physical location. The first computing device and the second computing device are joined in a use session of the particular program. It is determined that the first computing device displays a first user interface of the particular program at a first instance, the first user interface showing a first context in a plurality of contexts. The second computing device displays a second user interface of the particular program at the first instance based at least in part on the first user interface showing the first context, the second user interface showing a second context in the plurality of contexts.
