Lock Me is a status bar tool that enables easy screen locking. It includes a customizable icon that can be altered in color, and also supports global shortcut keys with adjustable modifier keys.

Lock Me offers three global shortcut options for easy access: Option+Command+L, Control+Option+Command+L, and Shift+Option+Command+L. This makes it easy to use no matter what your personal preferences or workflow entail.
Additionally, Lock Me offers a fun little gimmick feature: the ability to select the color of the icon that appears in the status bar. It's a small touch, but it adds a little bit of personality to the app.
Best of all, Lock Me won't cost you a dime. That's right, it's completely free to use. Whether you're an individual user or buying for an entire team, this app won't cost you a penny.
Lock Me also supports multiple languages, including English, French, German, and Simplified Chinese. This makes it easy to use no matter where you are or what language you prefer.
Overall, if you want a dead-simple and free app for locking your screen, Lock Me is definitely worth trying out. It's basic, but that's what makes it so effective.
