ArtDeck vs Proref

ArtDeck is a reference board for iPad, iPhone, and Mac. Collect images, videos, links, and notes, then arrange and zoom them on an infinite canvas. Make a moodboard or open the built-in tools when you want to analyze value, color, composition, or motion. You can also keep references next to Procreate on iPad or your creative apps on Mac. iCloud sync is optional. CAPTURE NOW, USE IT ANYWHERE See a texture, a color combination, or a striking composition while you're out? Take a photo right inside ArtDeck and drop it on a board. Because your boards sync, it's there on your Mac and iPad, ready next to your design, 3D, or drawing tools. COLLECT FROM ANYWHERE • Shoot photos and video on iPhone and iPad; on Mac, take the photo with the webcam or your iPhone • Import from Photos or Files • Scan a document on iPhone or iPad, or use Continuity Camera on Mac • Save any link as a card, or paste a link to an image, video, or PDF to import it • Drag and drop, paste, or use the Share menu from any other app • Opens all common image formats, plus WebP, AVIF, JXL, HDR, EXR, and SVG. Video, GIFs, and PDFs up to 300 pages • HDR images and video at full brightness on capable screens, for the whole app or per board STUDY WHAT YOU COLLECT Study any image or video frame through the ToolBox's five lenses, without touching the original: • Values: grayscale, a value ladder, and Notan to read your darks and lights • Color: pull a palette from any image, or see its temperature and saturation zones • Composition: overlay grids, test new framings, or check the symmetry • Read: simplify to the big shapes, find where detail piles up, follow the edge hierarchy • Measure: drop plumb lines, read an angle off a snapping guide, and compare two lengths The Analysis panel shows value range, a histogram, hue, saturation, and color distribution. Export a study, or keep a copy on your board. Step through GIFs and video frame by frame, with onion skin and a GIF filmstrip ANNOTATE AND DRAW • Mark up an image, or draw directly: pen, highlighter, and shapes • Draw a stroke, then hold at the end to straighten it ARRANGE IT YOUR WAY • An infinite canvas to drag, scale, rotate, and zoom • Snap to objects and grid; align, distribute, and tidy up • Group and nest, reorder, lock, with undo and redo YOUR BOARDS, EVERYWHERE • The same boards on iPhone, iPad, and Mac, synced through your iCloud • Works fully offline: sync catches up when you're back online • Choose which boards sync • Split View and Stage Manager on iPad • Keep your window on top of the others on Mac YOUR GALLERY • Carousel and grid views of every board • Labels and multi-label filtering • Favorite, archive, rename, or duplicate any board MAKE IT YOURS • Dark, light, and high-contrast themes • Set one theme for the whole app, or one per board • An editor to fine-tune the colors and create your own themes • Import and export themes by file or link ACCESSIBILITY • VoiceOver support across the app, including items on the canvas • Respects Dynamic Type and Reduce Motion • A theme editor that checks color contrast and flags colors that are hard to tell apart EXPORT AND HAND OFF • Export a whole board or just a selection • PNG, JPEG, HEIC, or PDF, up to 8K, with a transparent background where the format allows • Save a whole board as one .artdeck file to back up or hand off TRY IT FREE, KEEP IT FOR LIFE Start with a free, individual 7-Day Trial.

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.
