PurePin 0.9.0

PurePin 0.9.0

The first public preview of PurePin. Capture a region or full screen, annotate with arrows, text, and freehand strokes, and pin screenshots or clipboard images over other windows. The app processes images locally and requires no account.

Validation and limits

• Apple M1 Pro on macOS 27.0: the Release test suite passed all 121 tests, including capture, editing, pinning, and resource lifecycle checks.
• A separate instrumented Release build completed 20 capture cycles each for cancel, copy, and arrow-plus-copy on the same product code. See the measurement method and data for its scope.
• The Universal package includes Intel code, but has not been tested on Intel hardware. Cross-app physical shortcut triggering and first launch from a downloaded DMG have not been verified for this preview.

If F1 or F3 is already assigned to a macOS control, use the fn / Globe key or change the shortcut in PurePin Settings. Screen capture requires permission in System Settings → Privacy & Security → Screen & System Audio Recording.

Downloads
