Fineliner

On iPhone Duo

A notebook app that is at its best on Duo with Apple Pencil. You hand-draw the elements that become the app’s interface, even the font, then write straight onto the page. The closest thing to a paper notebook that folds shut.

Works in

• Unfolded

  Uses the full 7.6-inch inner display: more columns, side-by-side panes, bigger canvas.

• Closed

  A purpose-built layout for the 5.4-inch outer display, not just a shrunken one.
