Have you ever driven away in your car only to realize you left your cell phone at home? We’ve all done it and it’s really frustrating. Now there’s a device called Bringrr that will make sure you never leave home without it. The Bringrr stays in your car’s 12v outlet and pairs up with your phone via Bluetooth. If you start your car and your phone is not within a short range (10-15 feet approx.) then the Bringrr lights up in red and beeps to tell you that you don’t have your phone with you. The other cool thing it does is that if your phone’s battery dies while in the car it will also beep (since there is no longer a connection) reminding you to charge up. Bringrr costs around $35.
