MyRingGuardAn avid runner by the name of Rachel Owens who usually spends time running alone in parks and in the dark wanted to device a way to quickly let her friends and family know if she was hurt, attacked or needed help. Since sometimes it’s even pressing dial on the phone can be one of the most challenging things to do when you’re in pain or you’re running from someone and you’re panicking. She went back to the drawing board and came up with a device called the MyRingGuard.

The MyRingGuard is basically a ring that you wear around your finger, and all you have to do is press the button on it when you’re in trouble. Since the ring is paired up with your phone (Android-only at the moment), it connects to the app on your smartphone, and sends a text message with a GPS location to preset contacts. While it’s no Green Lantern ring, it does work well enough for its intended purpose. Just be sure you don’t accidentally press the button when you’re not in trouble.

Unfortunately the MyRingGuard is still in its prototype stage and isn’t up for sale yet – it’s part of a crowd funding site called indiegogo. Prices for pre-ordering the MyRingGuard start at $39. Find out more.
