Beam

Beam 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 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)
