I’m not one to get into the check in craze but I think I’ll make an exception for Imaginaria.
I’ve just come across an app that lets you share what you’re reading in a new and clever way. Rather than go on a site like GoodReads and tell fellow readers about your latest book, Imaginaria lets you check in to the fictional locations in the book. You can also get updates on other readers check ins and through the updates discover new books to read.
You can find the app in iTunes.
