Readmap has a new twist on the check-in format. Now instead of checking-in with Foursquare or Google Latitude you can check-in when your read.
Users of the Readmill app for iPad can choose to track where they read by enabling location tracking in the app. Readmap can then visualise your Readmill check-ins and show where you have been reading books using Google Maps.
To create a Readmap of your reading locations you need sync the map to a Readmill account.
