The absolutely worst thing about losing your keys, wallet, shoes and other essential stuff you carry around is that you can never find it until you’ve turned the whole place upside down looking for it. Stop being that loser by keeping track of your things with StickNFind Stickers. Instead of finding a lost item in the last possible place, the app will lead you straight to it. Heck, you could even stick one on the collar of your dog or cat, turning it into a GPS tracking device. The stickers communicate with your device using Bluetooth, and give out a buzz and a flash of light so that you can zero in on the location. If you’re leaving it behind somewhere and going out of range, you get a warning on the app.
