CheckMate is a Free App that instantly detects and shows you your friends when you are at the same Shopping Mall, Sports Stadium or other Place of Interest (POI) at the same time. On entering the location boundary, CheckMate will temporarily store your presence and if you remain within the vicinity for more than 5 minutes, CheckMate will integrate with your contacts and let you see who else is there at that moment, all these will be done in the background without your interaction. Once you leave the location, CheckMate can no longer detect the location of any of your friends. CheckMate shows you a history of places you visited.
