About Voltascano
Voltascano displays an Android phone’s current battery voltage in the status bar and in a persistent notification. This keeps the reading visible while the user is working in other apps. The app can start automatically after reboot and includes a control to exit completely when continuous monitoring is no longer wanted. The product is intended for people who want to observe voltage readings during charging or normal use. Its description suggests that patterns may be informative, but voltage alone should not be treated as a definitive measure of battery health or charger quality. The app reports a sensor value; it does not provide a documented diagnostic test or independent assessment of the battery. Voltascano is described as ad-free, compatible with Android 8 and newer, and designed to use little memory. The supplied evidence does not specify the update interval or which phone models expose the same voltage information. Its core function is a persistent battery-voltage readout with automatic startup and a manual exit control.
