什么是 ScreenMark？
ScreenMark is a local-first macOS menu bar app for presenting and explaining screen content. It combines live zoom, drawing and annotation tools, whiteboard overlays, freeze frames, snipping, break timers, cursor emphasis, and screen recording in one menu bar workflow.
The app works without an account and is designed to operate offline. The product site states that drawings and captures are not uploaded to a ScreenMark server. It supports Apple Silicon and Intel Macs running macOS 15 Sequoia, with a free iPhone companion for local-network remote control.
ScreenMark 能做什么？
Freeze, snip, and snapshot
Pause the display to discuss a specific moment, annotate the frozen frame, or drag over a region to save it to the clipboard or disk. Annotated snapshots render at Retina quality.
Whiteboard and break timer
Use a blank whiteboard or blackboard overlay for sketching, or run a full-screen countdown with visual background presets, a system clock overlay, and audio alerts.
Screen recording with audio
Record the screen to MP4 while mixing system audio and microphone input in real time. On-screen annotations are included in the resulting video.
Cursor emphasis
Pro cursor tools include a flashlight that dims the surrounding screen and a colored pointer ring in circle, squircle, or rhombus shapes, with adjustable visual settings.
iPhone remote control
The free iPhone companion connects to the Mac over the local network for presentation control, including highlighting, flashlight mode, drawing, and cursor movement.
