Download MightyMonitor Widget – Battery‑monitoring widget for Mac Bluetooth devices
Overview
MightyMonitor Widget is a lightweight, Mac‑only dashboard widget that gives you real‑time insight into the battery status of your Mighty Mouse and Apple wireless keyboard. If you’ve ever been caught off‑guard by a dead mouse or an unresponsive keyboard in the middle of a project, this tool removes the guesswork by displaying two clear dials that change colour as the charge drops. The widget lives on your macOS Dashboard (or Today View on newer systems) and updates automatically, so you never need to open System Preferences or check the Bluetooth menu.
While it focuses exclusively on Apple’s own Bluetooth peripherals, the simplicity of its design makes it an indispensable companion for anyone who relies on a wireless mouse or keyboard for daily work. The only configuration option is a toggle to hide either the mouse or keyboard monitor if you only use one device. Although it doesn’t yet support third‑party Bluetooth accessories, the precision and visual clarity it offers for Mighty Mouse users is unrivaled.
The widget is free, secure, and updates silently in the background, ensuring that you always have an accurate picture of your devices’ power reserves without any extra hassle.

Overall Rating: 4.5/5
Review Summary: MightyMonitor Widget delivers exactly what it promises – a clear, low‑overhead battery monitor for Apple’s wireless peripherals.

Frequent updates keep it compatible with the latest macOS changes, and the free price tag makes it a risk‑free addition to any Mac workflow.
Frequently Asked Questions
Does MightyMonitor Widget work on Windows or Linux?
No. MightyMonitor is a macOS‑only widget built with Apple’s Dashboard/Today View framework, so it cannot be installed on Windows or Linux systems.
Can I monitor third‑party Bluetooth devices like a Logitech mouse?
Currently the widget only reads battery information from Apple’s Mighty Mouse and the Apple wireless keyboard. Support for other brands is not planned for the near future.
Is there a way to receive a sound alert when the battery is low?
MightyMonitor relies on colour changes for low‑battery warnings. It does not include sound or notification alerts, though you can pair it with macOS’s built‑in Battery notifications for a more comprehensive solution.
How often does the widget refresh the battery status?
The widget polls the Bluetooth device every 30 seconds, providing near‑real‑time updates without noticeable impact on system performance.
Is MightyMonitor Widget safe to download?
Yes. The developer signs the widget with an Apple‑approved certificate, and the download is hosted on a reputable site. macOS Gatekeeper will verify the signature before installation.

For anyone who depends on a Mighty Mouse or Apple wireless keyboard, MightyMonitor Widget fills a niche that macOS itself does not address directly. Its instant visual feedback, minimal resource usage, and zero‑cost price make it a practical addition to any Mac workflow.

If you’re tired of surprise battery failures that interrupt your work, installing MightyMonitor Widget is a quick, secure, and free solution that will keep you one step ahead.
