Monkey Flash

Your Mac has many windows. Your attention needs one.

Monkey Flash keeps the window you are using bright and gently dims everything around it. A crowded desktop becomes calmer, so writing, coding, email, research, and design work are easier to follow.

Start immediately

Monkey Flash works without Accessibility, Screen Recording, or Input Monitoring permission. It does not read screen contents, window titles, documents, or keystrokes.
