Editor's Overview

Beam is a battery application developed by montafra, packaged as a single Android APK of version 1.9 weighing in at 4.49 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 4.49 MB, so it installs quickly even on modest connections.
This build is signed by "montafra" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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 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

Frequently Asked Questions

Is Beam free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Beam require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Beam safe to install?
We link to the exact APK published by montafra. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Beam?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
