Personal safety is always a concern, but being able to feel safe while discreetly alerting the authorities is a difficult balance to maintain. The SafeRing appears to be a normal ring accessory but is actually a powerful smartphone tool. With a miniature switch designed to avoid accidental triggering, the SafeRing can trigger the alarms on your phone and send GPS data to an emergency contact via text. It’s a low-key version of the Cuff line of Bluetooth-enabled safety jewelry. The ring can also be put to other non-emergency uses, such as locating a lost phone or activating a camera for a hands-free selfie. Backers can get a SafeRing in September 2014 for $35.
