Why does Good Beer Guide Mobile need a subscription?

Before September 2012, the app followed the written edition with each edition having to be paid for in September just like the book.

We have changed the app now to be a subscription for a year, so you will always have the latest edition during your subscription period. This makes it fairer to people who buy the app in August, and who would otherwise only get a few months worth of use before having to buy the app again if they want to keep the information up to date.
