Premium subscriptions are personal and linked to a single user account in 27 Crags. This means that using the same account/Premium on multiple devices is not possible.

The exception to this is the website and app. You can be logged into the website (27crags.com) and one app (phone or tablet) at the same time with the same account.

If you try to log into multiple apps (phone or tablet) at the same time, you will get an error message "This account is used in multiple devices". In order to log in to a new app, you need to log out from the previous one first.

If you don't believe you are logged in on a second device and are seeing this error message, contact us.
