DrawAnywhere

DrawAnywhere lets you sketch, annotate, and highlight directly on top of any screen — great for video courses, tutorials, and presentations.

Drawing tools

• Freehand pen, rectangle, ellipse, and laser pointer
• Pixel eraser; stroke eraser via stylus button
• 50-step undo/redo
• HSV color wheel, 18 presets, recent colors, hex input
• Stroke width and opacity sliders

Canvas and gestures

• Infinite canvas — pan and pinch-to-zoom freely
• Three-level lock (none, zoom only, all) with HUD indicator
• Two-finger pinch: zoom | double-tap: reset zoom | triple-tap: reset position
• Three-finger double-tap: toggle passthrough | triple-tap: hide canvas

Toolbar

• Horizontal and vertical layout, draggable anywhere via long‑press
• Auto-dims after 3 seconds of inactivity
• Hide canvas or pass touch events through to the app below
• Finger-drawing toggle for stylus-only mode

Convenience

• Quick Settings tile to toggle the service
• Drag the toolbar to the bottom of the screen to close the app
• Second-launch closes the service
• Brush hover preview while drawing

Tips

• Turn on Clear canvas on hide to auto-clear when hiding the canvas (passthrough is also disabled).
• Turn off Open canvas on start to hide the canvas on startup.
