Tetherboard makes app-enabled batteries that allow people to remotely control battery-operated devices from their smartphones or tablets.
We sell a family of app-enabled batteries (called Tethercell) and a free app that are used to remotely switch battery-operated devices on and off, set on and off schedules, and to monitor device power levels. The product is used for convenience, for fun, to save energy and to increase safety. Our customers include parents, businesses, and technology enthusiasts. The AA and 9V versions will be the first to be made available.
