Splashy Sketchpad is a native macOS infinite whiteboard built for brainstorming, planning, note-taking, diagramming, and visual thinking.

Most whiteboard tools today live in the browser, require accounts, or focus heavily on collaboration. Splashy takes a different approach: a fast, lightweight, native experience that gets out of your way and lets you focus on your ideas.

Key features:

• Infinite canvas
• Smooth ink rendering
• Smart shapes
• Layers support
• Grid pages
• Native macOS experience
• Dark mode
• PDF export
• Lightweight and distraction-free

I built Splashy because I wanted a simple whiteboard that launches instantly and feels like a native desktop tool rather than another web app wrapped in a window.

Whether you’re planning software architectures, sketching UI ideas, taking visual notes, mapping out projects, or simply thinking through a problem, Splashy gives you an unlimited space to work.

One-time purchase. No subscriptions.
