If you purchased the subscription through the App Store, your membership is connected to your Apple ID account. You can transfer it to your iOS devices only.
Here's how to do it:
Log into the App Store on your second device using the same Apple ID from which you made the Premium purchase. Tap Restore in Verv Profile settings or directly on the payment banner.
Note: the devices can't sync progress with each other.
If you subscribed to the app using the website or another platform, your membership is connected to the device where the purchase was made on and can be used only on it.
At the moment, there is no way to move purchases from iOS to Android (and vice versa).
If you keep experiencing issues, please send us an email at email@example.com, and we'll help you restore the purchases.
