<i>Beam</i> is a lightweight battery monitor. It pins a live power, current, voltage, or charge readout to your status bar and opens into a full breakdown of battery metrics inside a clean, themeable app. Pick which unit appears in the status-bar icon (W, A, Ah, V, Wh, °C, %), or stack several values in the notification body. Privacy first: • No ads • No tracking • No data collection • No third-party sharing • No unnecessary permissions Battery metrics in the app: • Power (watts) • Current (amps) • Voltage (volts) • Energy (watt-hours) • Temperature (°C) • Charge level (percent) • Charging status and plug type • Charging since (date / time) • Time to full charge Personalisation: • Material You dynamic colour (Android 12+) or a custom seed colour from a 12-swatch palette • Light, Dark, System, and OLED-black themes • Optional hero backlight glow and haptic feedback Device compatibility: • Power-scalar correction for phones that report µA instead of mA • Inverted-current toggle for phones that flip charging direction • Adjustable polling interval Open source on GitHub: https://github.com/montafra/beam Every donation is welcome and helps support my future projects — see the in-app About section for crypto addresses. Note: notification permission is required to display the status-bar indicator. Open the app once to start the indicator service.
