Hey, we could use some help testing a new open source app out on as many different devices as possible. It is already published; search for "mobflare" in Google Play. More info and a direct link are at www dot mobflare dot com. We've done some initial testing on a variety of phones and already fixed some bugs that turned up as a result. For the most fun testing, you need a friend or two nearby since it is intended as real-world multi-user. In particular, we're interested in hearing about how well the timing works (to decide whether we need features for adding a bias to each phone's clock). Thanks!
