Your real battery level, live in the signal.
The battery distress beacon
When your battery dies, light the signal.
Plug in, pick a target, walk away: at 80 or 100 percent BattSignal fires the searchlight and calls you back with a dramatic synth score until you stop it or unplug. In between: the prettiest battery beacon in the night sky.
Coming to the stores
BattSignal launches soon for iOS and Android. Until then: keep a charging cable handy.

-
A charging alarm with a show
Pick 80 or 100 percent and walk away: once your battery gets there, the signal fires and keeps sounding until you stop it or pull the cable.
