In-app purchases good for only one device

The point of buying a program like this is to have a map available when wi-fi or data services are disabled. Unfortunately, in-app purchases are only good for that one device, even if you have multiple iOS devices on the same Apple ID account. You can not even transfer your map purchase to another device. If this annoys you, dont buy any of these 700 maps.
