When you make a connection in Termius, that session is logged in History. This provides a log of activity and allows you to add these past sessions as hosts.
On the desktop, history can be found in the left-hand panel.
Click an item to see its details, connect, add as a host or remove.
To browse history on a mobile, navigate to the History screen.
Then tap and hold a history item and choose the relevant option.
With location tracking Premium users can bypass the restrictions of iOS, which forbids using the app (most apps) in the background.
This will also allow storing the information about the location in history with the ability to see it on the map. Location tracking will be enabled only when you have active connections just to keep them from disconnecting.
