Mock LocationHow many devices can be linked to one account?
One device on the free plan, several on Premium. The current numbers are on the Premium page.
A device is a specific installation of the app: reinstalling on the same phone takes a new slot in the list. So if you have reinstalled the app, it makes sense to revoke the old entry manually.
The list of linked devices is in your account on the website, and that is where they are revoked.
