Tethercell

Keep track of all your battery-powered toys and devices with the Tethercell. This brilliant, app-connected add-on works with any device that takes AA batteries. You simply replace one of the AAs with the Tethercell, which has a AAA cell loaded inside. Once connected to the app, you'll be able to remotely turn your battery-powered stuff on and off, set device schedules and timers, get alerts when the batteries are running low, and, soon, even find Tethercell'd devices via a proximity function — so you'll never have to dig for the TV remote again.
