BindNotes
Read full descriptionHide full description
Your notes. Linked. Notes shouldn't be limited by the size of a page. But linear pages and infinite canvas aren't the answer ā you just get lost. BindNotes takes a different approach: go infinitely deep, not infinitely long. Lasso any handwriting with Apple Pencil, link it to another page, and tap to jump. Pages give you focus. Links give you depth. Your notes become a connected network of ideas ā not a stack of dead-end pages. BindNotes is a notebook app built for Apple Pencil. Write, sketch, and draw like any notebook ā then connect your pages. Headers & Outline Assign header levels (H1āH5) to any page. Headers build a navigable outline for your notebook ā tap to see the full structure, drill into sections, jump to any page. Color-coded by level so you can see hierarchy at a glance. Links let you follow a thought. Headers let you see the shape of your notebook. Together, they turn a stack of pages into a system. Page Overview See every page connection in your notebook as a visual graph. Arrows show which pages link where. Spot structure, find orphaned pages, navigate by tapping. PDF Annotation Import any PDF into a notebook. Annotate with pen, highlighter, and lasso. The highlighter lifts actual pixels from the PDF ā highlighted content becomes a visual element you can work with. Add headers to organize the PDF. Create links between pages. Turn a static document into something navigable. PDF Export Export your notebook as a PDF. Links become clickable cross-references. An outline page is auto-generated. Your handwritten notebook exports like a professional document. Sync with iCloud Drive Notebooks sync across iPhone, iPad, and Mac via iCloud Drive. No account. No server. You control where your data lives. All Features Are Free No purchases, subscriptions, or ads.

You can use the canvas offline without an Asympta account.

The purchase does not include additional iCloud or Google Drive storage. Google Drive connection is optional and uses only the app data scope.

ON IPHONE DUO Move between the outer screen and a wider, unfolded canvas. Tools and writing controls adapt to your current window.

Verdict
The clearest difference is update cadence: Asympta Writing at weekly against BindNotes's monthly. Asympta Writing also leads on iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
