It is not possible to change your account email address directly.
If you have an active license, we can transfer it to your new device.
Log in to Radarbot with your new email account.
Open the side menu (≡) and tap on [Customer Support]
Tap [Send a message]
Tap [Payments and licenses]
Complete the assistant and, if your license is valid, we will transfer it to your new device/account.
If we cannot identify the license, we may ask you for the purchase receipt from the app store to ensure there are no errors.
