WinPin is built by Catapulsion, a software studio that builds native desktop and mobile applications with a focus on clean code, solid architecture, and maintainable systems.
We build tools we want to use ourselves. WinPin started because we got tired of rearranging windows every time we unplugged a monitor or switched desks. macOS doesn't remember where your windows go. Now it does.
WinPin is a native macOS app built with Swift and SwiftUI. No Electron, no web views, no runtime overhead. It talks directly to the macOS Accessibility and Window Server APIs, which means it launches fast, uses minimal resources, and works the way a Mac app should.
WinPin runs entirely on your Mac. No account, no cloud sync, no telemetry. The only network request is an update check via Sparkle, and even that sends only what's needed: your app version, macOS version, and license status. Read our privacy policy for the full picture.
