Volt - Battery Tracker

Track every battery in the house so you always grab the right size, charged.

Volt tracks every battery-powered device in your house: remotes, smoke detectors, keyboards, toys, and more. Log when you last swapped batteries and Volt estimates the charge level, so you know what is running low before it dies.
