Memory Meter 3: System Monitor

Memory Meter 3 is a beautifully designed app for monitoring your Mac’s memory usage in real time via your menubar. It gives you a clear, accurate view of how your system memory is being used, with an interface that is easy to understand and genuinely pleasant to look at. Memory Meter 3 helps you spot which apps are using the most memory (RAM), so you can decide what to close and free up memory. Everything updates live, so you always know what is happening right now. You can choose to receive notifications when apps have been inactive for a while, for example after 30 minutes. It is a simple reminder that something is still open even though you are no longer using it. The interface is fully customisable. Switch between a clean light theme and a polished dark theme, and choose a detailed or compact layout depending on how much information you want at a glance. Memory Meter 3 is fast, elegant, and designed to feel at home on macOS.
