A total scam.
This app is designed to randomly lock you out of the account where it no longer lets you log in despite having the correct password, as a result you will have to create new account. The problem? The car will still be stuck to the old account no longer allowing you to use the IMEI of the device unless you remove car from it which can’t be done since you can’t log into original account anymore. The over $100 device is virtually bricked at the point and you have to get a new one. Not worth it.
