SpinWin lets macOS users rotate any app window via menu bar
A developer has released SpinWin, a free, open-source macOS menu bar app that lets users visually rotate or spin individual application windows. The project was inspired by a social media reel suggesting viewers flip their phone upside down, prompting the creator to look for a similar tool on macOS. Finding no existing solution, the developer built one using macOS's Accessibility API to move target windows offscreen while they continue rendering. Window contents are then captured via ScreenCaptureKit and displayed on a transparent overlay with a rotating CALayer. SpinWin is written in Swift, released under the MIT license, and is both signed and notarized for macOS.
