Drawing apps with a bigger window
An infinite canvas is only ever as big as the window you look at it through. On a folded phone that window is a keyhole, and almost every design decision in a mobile drawing app is an apology for it.
Drawing is the category where screen size is not a convenience but the medium. A brush stroke is made at a scale, judged at another, and corrected at a third, and a small screen means constant zooming between the three. Add the tool palettes, the layer list and the colour picker — all of which have to live somewhere — and a phone canvas ends up being the part of the screen nothing else wanted.
One honest note about the obvious absence. The app most people would name first in this category publishes an iPhone edition whose listing declares no tablet layout and no universal binary, which is one of the two checks every entry on this site has to pass. That is a fact about the listing rather than a judgement about the app, and it may well change — but a shortlist whose rules bend for a famous name is not a shortlist.
The handwriting caveat from the notes list applies here too, and harder: Apple's product page lists Apple Pencil (USB-C) support as arriving later rather than at launch, and drawing with a finger is a different activity. The apps lower down this list, the ones about diagrams and layout rather than brushwork, are the ones least affected by that.

Concepts
TopHatch, Inc.
A vector sketchbook on an infinite canvas, which makes it the app on this list whose core feature is most directly limited by viewport. Vectors mean the strokes survive being moved and rescaled afterwards, so the drawing you start on a train is still editable on a desk.

Sketchbook®
Sketchbook, Inc.
A long-standing sketching tool that runs from a rough idea to a finished piece, with a brush set deep enough to matter. Brush work is judged at full size, and full size is the thing a folded phone cannot offer.

Adobe Fresco: Draw & Paint App
ADOBE SYSTEMS SOFTWARE IRELAND LIMITED
Painting with a very large brush library, built for the tablet first by the developer's own description. An app designed around a tablet canvas and then fitted to a phone is exactly the kind that has something waiting for the extra room.

Infinite Painter
Sean Brakefield
Painting and sketching with a feature set aimed at people who do this seriously. The deeper the toolset, the more of the screen the tools take, and the sharper the trade against the canvas they sit on.
- 5
ibis Paint X
ibis inc.
Drawing and animation with a very large user base and a strong following in comics and manga work. Frame-by-frame animation is a timeline plus a canvas, which is two things wanting the same screen.

Tayasui Sketches
SKETCHES SRL
Built around realistic media — the kind of brushes meant to behave like actual ink and watercolour. That realism is only legible at a size where the texture of a stroke is visible, which is an argument about pixels, not preference.

Linea Sketch
The Iconfactory
The Iconfactory's sketching and note-taking app, deliberately simpler than the painting tools above it. Simplicity means fewer palettes competing for space, so it is the entry that works best folded — and still gains when opened.
- 8
Figma
Figma, Inc.
The mobile companion to the design tool, for viewing, sharing and mirroring work in progress. Reviewing a design on a phone has always meant seeing a fragment of it; a wider screen is the difference between checking a screen and checking a flow.

OmniGraffle 3
The Omni Group
Diagrams rather than drawings: boxes, connections and structure, from a developer with a long history of doing exactly that. A diagram is one of the few images that is genuinely unusable below a certain size, because the whole point is seeing how the parts connect.

Freeform
Apple Distribution International
A shared board with no edges, free to create in and collaborate on, already on the phone. It is last because it is the least specialised, and on the list because an unbounded board is the purest case of a canvas limited only by the window.
The selection and the order are ours. Each entry is written from that app’s own App Store listing, linked beside it, and this page from Apple's iPhone Duo product page. Drafted with AI assistance and checked back against those sources before publishing; the disclosure page explains how. The iPhone Duo has been on sale since 23 October 2026 and nothing here has been seen running on one, so what each entry says about the fold is an argument rather than a test.
