Proref

Proref is where your references live while you draw — and where the finished piece goes afterwards. GATHER YOUR REFERENCES Drop everything you're looking at onto one huge canvas and arrange it into a board. Import from Photos, your camera, Files, a web link, the share sheet, or by dragging straight in from Safari. Zoom from 2% to 25,600%, so the board grows with the project. WORK BESIDE THEM Proref is built for Split View: your references on one side, your drawing app on the other. Sketch and annotate over them with Apple Pencil, with pressure. Tune brightness, contrast and saturation, or crop non-destructively — the original is always recoverable. A minimap shows where you are, and saved views jump you back to any spot in one tap. KEEP THE PIECE, AND THE LESSON When something's finished, keep it. Attach a piece to the board it came from, open it full screen, and see everything you've made on a dated timeline — as a gallery to swipe or a list to scan. Note what worked and what didn't while it's fresh, star the things to carry forward, and those notes sit in a pane on the board while you draw the next one. If you'd rather Proref stayed purely a reference app, turn the art journey off in Settings and it does. PRIVATE BY DEFAULT No accounts. No sign-in. No server. No tracking, no analytics, no ads. Your boards, your artworks and your critique notes stay on your device. FREE, WITH A ONE-TIME UNLOCK Proref is free to use with 2 boards, 10 images per board, 3 saved views, 5 finished artworks, and 3 focused critique notes per piece. Proref Pro removes those limits and unlocks every feature — a single one-time purchase, not a subscription. Buy it once and restore it on your other devices.

Verdict
The clearest difference is update cadence: Proref at every 6 days against Art Reference's every 2 weeks. Proref also leads on iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
