A perfect tool for the outdoorsy types or even festival goers, Beartooth uses radio technology to keep your smartphone working even when cell service or Wi-Fi connections aren’t available. Resembling an external battery case (because it is) with a visible antenna, this device can place calls to other Beartooth users or communicate on an open channel within a range of a few miles much like a two-way radio. This device will also allow text communication and geo-location, helping you track other users as well as yourself. Priced at $250 USD, production for Android and iPhone versions are set to enter the production phase in 2015. Visit Beartooth.com for more information.
