I saw a story on our local news about this. The military has been studying the sounds a bee colony makes to make it easier to keep bees for mine detection. Evidently the buzz changes when certain conditions occur such as queenlessness, foul brood, varroa infestation, etc. This app records the sounds inside a hive and compares it to a rather extensive database and can diagnose colony issues. I am not suggesting anyone contribute! I have no dog in this fight. Watch the Kickstarter video for a sense of what this is, seems pretty cool to me.
