Of course! It's now possible to connect Tinitell to more than one phone via the Tinitell app using the same account. You can login with the same account credentials on another smartphone, and you will be able to access the Tinitell app settings and see the device's GPS positioning.
We are now developing a new feature of the app, that will allow several accounts to be associated with the same Tinitell, but we need to test it extensively before the release, both on iOS and Android. This is a very sensitive feature from a security point of view and we want to make sure there will be no weak points.
If you want to connect Tinitell to a different account (full settings management) you need to perform a factory reset on the Tinitell.
