I have been busy enhancing my Android app on Google Play that uses the camera as a view finder to locate your friends at places that interest them, a.k.a. points of interest.
There are actually two apps: 1. Ice Cream Sandwich and lower; 2. Jelly Bean and up. This was necessary because version 1 was crashing on the Samsung Galaxy 3.
Below are typical screen shots of geotags in Los Angeles.
Note that this Android app also creates the geotags, so points of interest are relevant to your clique or set of friends. You can also create geotags remotely with the companion website at SpiderOnFire. Your W.A.R. handles are anonymous and all content can be deleted at your discretion.
