About

InfiniteNote

Read full description

An infinite canvas built for planning, design, and shaping ideas — think without page breaks. When you're working an idea out, your thinking doesn't fit on a page. With InfiniteNote, you put your iPad in landscape, pick up your Apple Pencil, and lay your thoughts out in space on one borderless canvas. Place notes and diagrams apart, connect them, and zoom out to see it all. Instead of flipping pages, you pull back for the whole picture, then dive back in — your train of thought never breaks. [Who it's for] - Planning products and initiatives - Thinking through designs and architecture with diagrams - Spreading research across one canvas to see the connections - Brainstorming and sketching ideas by hand [How it's different from a regular notes app] - No page breaks. Your thinking is never cut off. Expand in any direction. - Lay things out in space. Connections and structure become visible. - Everything accumulates on one canvas. Go back anytime, connect, and build on it. A minimap keeps you oriented as it grows. [Main features] - Borderless infinite canvas with smooth ink - Minimap to jump anywhere in a large note - Import images and write directly on top of documents - Export as PDF to share and archive - iCloud sync to continue on iPad and iPhone - Dark mode [Pricing] Core features are free. Try your thinking space for free, and when you want a separate canvas for every theme, a one-time purchase (no subscription) removes the note limit.
