AlpineQuest & OfflineMaps

I am purchasing a second hand phone primarily to have as a back up in mountains. I want to install Alpine Quest on it in case my normal phone stops working. Do I need to pay for it again for that phone or can I download it under the same registration as the Alpine Quest on my existing phone ? Thanks.

As long as both devices share the same Google account, you should be OK.

This applies to any application installed from PlayStore.

Great, thanks.
