How to use my subscription on another device? (iOS)

Updated over a week ago

1. Open the App Store app on your second device.
2. Sign in to the Apple ID where you made the purchase.
3. Download WiFi Map.

NOTE:

The subscription is tied to your WiFi Map account, so you can open the app on another device and just sign in.
If the same subscription is used on more than 5 devices, it will be blocked.
