Charmstone

Charmstone provides a fast way to launch and switch between applications on macOS using a single modifier‑key combination. By invoking the launcher, users can select an app from a compact list that appears near the cursor, allowing them to bring the desired program into focus without navigating to the Dock or using the standard Command‑Tab switcher. The interface is designed to be minimal, relying on spatial memory so that the target app can be reached with a single keystroke.

The utility is aimed at macOS users who want a quicker, keyboard‑centric method for changing tasks, especially those who find the traditional dock or Command‑Tab workflow cumbersome. It is a standalone application that runs on any recent macOS version and does not require additional configuration beyond installing the provided binary.

Charmstone is distributed through the Mac App Store and is marked as stable, indicating that it has reached a mature state for everyday use. The developer, Ryan Hanson, emphasizes a low learning curve and a focus on speed, positioning the tool as a lightweight alternative to more complex launchers.
