There are two options:
Option 1. Create another account to be used on the second smartphone and share the Findster modules from the original account to the new one - this way, the owner of this account will be able to see the modules' position.
Option 2. Log out of the original account on your smartphone, and log in with the same account on the second smartphone - since the modules are linked with the account, they will automatically connect to any smartphone when you log in with your information.
