MineWatcher Beta (com.tajchert.polminewatcher) on Google Play
Powerful app to monitor your miners at PolMine.pl, Bitcoin.cz, BtcGuild.com. It allows to check in background if all of your miners are working and create beautiful charts. It is still in development so don't be surprised as something wouldn't work 100% correctly.It works with BTC, DOGE, LTC (on polmine.pl).
