Simple and free application that allows you to post and share messages on the map. Your message will be placed inside a call-out (balloon). You can adjust the message location by dragging the call-out, so that you don’t have to worry about the location accuracy or moving to the actual location. The message will have an expiration date, so that it will disappear from the map automatically (max posting duration is 1 month). You can also post the message either in public or in private. In either case, you can send the message via HTML-capable email to another Android phone with mapPOSTER.
Version 1.1.0 added new features such as notifications on other users’ postings, a list view on the postings in the current area, an optional GPS selection to conserve the battery and so on. As of October 2011, the application is in beta.
