Reference Board Apps for Artists, Compared by Workflow

Compare the current options

Reference apps solve different interruptions. You may need a small board that remains visible while you draw, or one place to keep the sources and studies for a project. A large archive creates a retrieval problem, and a second device changes the platform requirements.

The comparison follows a project from gathering sources to using them beside an art app, studying them, and reopening the board on another device. Library search appears where it changes the choice.

Seven reference apps, compared by their strongest documented use
App and role	Strong fit	Check before choosing
ArtDeck Active project board and study	Images, video, GIFs, PDFs, links, notes, drawings, and adjustable study tools across iPhone, iPad, and Mac.	Apple platforms only. Gallery labels help with filtering, without the library-wide OCR or visual-similarity search found in some archive tools.
PureRef Desktop project reference canvas	Deep window modes, drag and drop, crop, grayscale, color picking, locking, drawing, arrangement, and GIF controls.	Runs on Windows, macOS, and Linux. PureRef does not list iPhone or iPad support.
VizRef Focused iPad project board	A focused image and GIF board with web drag and drop, batch import, auto-pack, crop, grayscale, and frame playback.	The listing is iPad-only, and version 1.1.7 has been current since June 2021.
Eagle Full desktop asset library	Batch browser capture, hierarchical and smart folders, saved filters, duplicate handling, broad search controls, and media previews.	Official downloads are for Mac and Windows. Eagle organizes a library rather than providing a native mobile board.
Reference Board Apple boards with library search	Infinite boards with mixed media, OCR, tags, detected objects, and color, similar-image, and natural-language search.	Requires version 26 of Apple's operating systems. Its documented organization is lighter than Eagle's desktop library.
Freeform General Apple canvas	A general canvas for mixed files and drawing across iPhone, iPad, and Mac.	Apple documents a general whiteboard, without reference-library search or dedicated image-study controls.
Milanote Creative project moodboard	Moodboards with images, video, GIFs, PDFs, notes, color swatches, templates, and access through desktop and mobile apps.	Mobile viewing and editing require an internet connection. Milanote is a broader project board without dedicated image-study controls.

Keep references beside another app

PureRef 2.1.3 has the most developed desktop-reference behavior in this group. Its window can remain above every app or one chosen app, pass mouse input through to the app beneath it, or turn selected images into separate overlays. It also has an extensive shortcut system with alignment and arrangement commands.

PureRef documents crop, per-image and canvas grayscale, color-code picking, drawing, item locking, and GIF playback with speed and frame controls. Its handbook does not describe adjustable value, palette, composition, or measurement analysis comparable to ArtDeck’s ToolBox. The ArtDeck and PureRef comparison examines that decision in more detail.

VizRef takes a narrower iPad approach. Its listing describes a compact board made to sit beside Procreate and other drawing apps through iPad multitasking. It imports images and GIFs, auto-packs selections, crops and flips images, toggles grayscale, and provides a GIF timeline with frame playback. Version 1.1.7 has been current since June 2021, so test import, export, and GIF timing on the iPad you use now.

ArtDeck provides a simpler always-on-top board on Mac. It fits when the active board needs video, PDFs, links, notes, or study tools and must move between iPhone, iPad, and Mac. PureRef remains the stronger choice when click-through behavior, app-specific attachment, or separate image overlays matter.

Choose a project board or a reference library

A working board usually belongs to a painting, sequence, or design. The useful unit is the material you need while making it: source images, footage, links, notes, and the studies you produce from them.

ArtDeck keeps that material on one board. Related items can be grouped or nested, arranged with alignment and distribution tools, and locked once the layout is settled. A saved value, color, or composition study can sit beside the source that produced it. In the gallery, labels, favorites, and archive status help you return to a known project.

PureRef saves an image-led project as a desktop scene and gives it deeper window controls. VizRef offers a smaller image and GIF board on iPad. Freeform and Milanote make sense when the references belong inside a broader project canvas.

Eagle is built around the library itself. Its browser extension collects single images, screenshots, or a batch from one page and can assign folders and tags during capture. The desktop app adds hierarchical and smart folders, saved filters, ratings, duplicate checks, batch operations, and searches by keyword, tag, color, shape, date, dimensions, or file type. It runs on Mac and Windows, with no native phone or tablet board.

Eagle and ArtDeck can work together on Mac. Keep the long-term library in Eagle. For a new project, export the relevant selection or folder, then drag or import those files into an ArtDeck board. The selected references can sit with project links, notes, video, and saved studies while the larger collection stays organized in Eagle. The handoff copies the files into ArtDeck; Eagle’s tags, ratings, and later library changes do not sync to the board.

Reference Board takes a lighter Apple-device approach. It combines infinite boards and mixed media with OCR, automatic tags, color filters, similar-image suggestions, and natural-language search. It suits someone who wants searchable boards on iPhone, iPad, and Mac. Eagle offers a broader set of controls for a large desktop asset collection.

ArtDeck’s labels help you reopen a project you already organized, but it does not have library-wide OCR or visual-similarity search. Eagle is the more complete choice for a large cross-project archive on desktop. Reference Board covers that search need across Apple devices with fewer documented asset-management controls.

Check where the app runs

ArtDeck carries boards across iPhone, iPad, and Mac and supports iOS 18, iPadOS 18, and macOS 15 or later.

PureRef covers macOS, Windows, and Linux but has no iPhone or iPad version. Eagle is available on Mac and Windows, while VizRef remains iPad-only. Reference Board stays within iPhone, iPad, and Mac and requires version 26 of each operating system, which may rule out older devices. Those boundaries matter more than a long feature list if you collect on one device and draw on another.

Freeform follows Apple’s devices. Milanote reaches more platforms through its desktop and mobile apps, although its mobile apps require an internet connection to open or edit boards. Both suit broader project boards; their documentation does not position them as dedicated image-study tools.

Platform support does not guarantee the same workflow on every screen. Test how the app imports a source, keeps a board visible beside your drawing app, and reopens the same project on the second device you use most.

Test the shortlist with one project

Pick the one or two candidates closest to the problem you have:

Keep PureRef on the shortlist for the deepest desktop window controls.
Compare VizRef and ArtDeck for an iPad drawing companion. ArtDeck adds mixed media, study tools, and the same boards on iPhone and Mac.
Use Eagle when the archive spans many projects. Choose Reference Board instead when library search needs to follow the board across iPhone, iPad, and Mac.
Consider Freeform or Milanote when references belong inside a broader project board rather than a dedicated study workspace.

Import the same material into each candidate. Build a board large enough to expose friction, close and reopen it, move to another device if that matters, and repeat the action that currently slows you down. A real project exposes interaction problems that a feature list cannot.
