🔴 Mute Notifier – Visual Microphone Mute Indicator for macOS

Mute Notifier is a lightweight macOS app written in Swift that shows a small red square at the bottom of each screen when your microphone is muted — giving you a clear, visual reminder so you never talk while muted again. Simple, unobtrusive, and built for multi-display setups.

📝 I'm using a Logitech mouse that lets me mute the microphone, at system level, through a custom action button configured in the Logitech application.
However, when I mute the mic, a small red square appears (with the Logi app) — but only on one screen. As a result, I sometimes kept talking while still muted without noticing it. 🤦‍♂️

To solve this, I decided to create a simple application that would remain clearly visible no matter which screen I'm looking at.

✨ Features
