The Noke lock is a Bluetooth enabled smart lock that eliminate the hassle of keys and combinations forever. The lock is compatible with iOS, Android and Windows Phones, and works in conjunction with the Noke app for smart, convenient security. Designed to be the simplest electronic device you own, Noke automatically finds and connects to your Bluetooth 4.0 enabled smartphone. Instead of fumbling for keys, simply walk up to your Noke, press the shackle, and instantly access your possessions. Nokes app even lets you share guest access with friends and family, so they can unlock your Noke with their own smartphone. You can allow a guest unlimited access, one-time access, or create a custom schedule of specific times and days of the week. For added control and peace of mind, Noke lets you monitor its history so you know where, when, and by whom your lock was accessed.
