App Description
Track voltage, current, and battery health in real time. No guesswork.
Volt Monitor is a simple, clear app for tracking your phone's battery status in real time.
Unlike other apps, Volt Monitor never invents or estimates values it can't actually measure. It shows only real data straight from Android's system APIs.

CHARGING SESSION DETECTION The app automatically detects when you plug in your phone and records the duration and progress of each charging session.
