The Best Miniature Painting Apps in 2026: An Honest Comparison
Last updated July 5, 2026
The best miniature painting app depends on what you actually need. Every app in this space falls into one of three categories: inventory trackers that catalog your paints (paintRack, Citadel Colour, MiniPaints), color matchers that find equivalent paints across brands (PaintVault), and guide generators that produce step-by-step painting instructions from the paints you own — a category with exactly one app: PaintGuide.ai. This page compares all six honestly, including what each competitor does better.

How to Choose a Miniature Painting App
Ask one question first: do you want help organizing your paints, or help actually painting the model in front of you?
If it's organizing, an inventory tracker is the right tool. They're mature, mostly free, and great at what they do — barcode scanning, wish lists, avoiding duplicate purchases. If it's painting, an inventory list doesn't tell you which paint goes where, in what order, or how to mix a color you don't own. That's the gap guide generation fills.
Each App, Honestly
PaintGuide.ai — best for guides from the paints you own
Upload a photo of your miniature, select the paints you own, and it generates a custom step-by-step painting guide using only those paints — with exact mixing recipes for colors you're missing, cross-brand matching across 435+ paints (Citadel Colour, Vallejo, Army Painter), and PDF export. It also does inventory (with an AI photo scanner of your paint shelf), but guide generation is the reason it exists. The honest trade-off: it's the only app on this list with a subscription for its core feature — one guide is free to try, then plans start at $4.99/month.
paintRack — best for cataloging a large collection
The most complete inventory tracker in the hobby, with a database of 27,000+ paints, barcode scanning to add bottles fast, cross-brand color matching, and saved recipes. If you own hundreds of paints across brands and want them organized, paintRack is genuinely excellent. What it doesn't do is tell you how to paint a specific model — recipes are ones you write yourself.
Citadel Colour: The App — best for official Warhammer schemes
Games Workshop's official app, and the definitive source for painting Warhammer models the "box art" way — paint-by-model schemes in Classic and Contrast methods, plus inventory and wishlist for the Citadel range. The limitation is built in: it only knows Citadel paints. If your collection includes Vallejo or Army Painter, it can't see them.
MiniPaints — best for sharing recipes with friends
An inventory app with a clever social angle: save paint recipes, organize them into projects, and share them via QR codes, with links to videos and images. Around 4,000 paints across many brands, plus a color-capture tool for finding similar paints from photos. Like paintRack, the recipes are ones you create — it doesn't generate them.
PaintVault — best free cross-brand color matcher
Focused and free: search thousands of paints and instantly find the closest match in another brand using Delta E 2000 color science, on web and Android with synced data. If all you need is "what's the Vallejo equivalent of this Citadel paint," PaintVault answers it well. (PaintGuide.ai offers free cross-brand equivalents too — and folds the same matching into its generated guides.)
Miniature Painter Pro — best for palette building from an image
A color-picker app: select colors from a reference image and match them against 2,500+ paints from 10+ brands, with a paint mixer and saved palettes. Handy for planning a color scheme from concept art. It stops at the palette — the painting order and technique are up to you.
When PaintGuide.ai Is the Right Choice — and When It Isn't
Choose PaintGuide.ai if your question is "how do I paint this model with these paints?" — you're a beginner with a starter set, a D&D player with a backlog of unpainted minis, or a 3D-printing hobbyist who prints more than you paint. Generated guides with mixing recipes are the whole product.
Choose something else if you already know how you want to paint and just need your collection organized (paintRack), you paint exclusively Citadel by the book (Citadel Colour), or you only ever need a quick equivalent lookup (PaintVault — or our own free equivalents pages). Plenty of painters pair an inventory app with PaintGuide and use each for what it's best at.
Frequently Asked Questions
What is the best app for miniature painting?
It depends on what you need. For generating custom step-by-step painting guides from the paints you already own, PaintGuide.ai is the only app that does it. For cataloging a large paint collection, paintRack is excellent. For official Warhammer paint schemes, Citadel Colour: The App is the source. For quick cross-brand color matching, PaintVault is a solid free choice.
Is there an app that tells you how to paint a miniature with the paints you already have?
Yes — PaintGuide.ai. You upload a photo of your miniature, select the paints you own, and it generates a custom step-by-step guide using only those paints, with exact mixing recipes for colors you're missing. As of 2026, it is the only miniature painting app that generates guides rather than tracking inventory or matching colors.
What's the difference between a paint inventory app and a guide generator?
Inventory apps (paintRack, MiniPaints, Citadel Colour) track which paints you own and help you avoid buying duplicates. Color matchers (PaintVault) find the closest paint across brands. A guide generator (PaintGuide.ai) goes a step further: it uses your collection to produce a complete step-by-step painting plan for a specific model, including mixing recipes. Many painters use an inventory app and a guide generator together.
Are miniature painting apps free?
Most inventory and color-matching apps are free or have free tiers: paintRack, Citadel Colour, MiniPaints, PaintVault, and Miniature Painter Pro. PaintGuide.ai offers one free guide to try, then paid plans from $4.99/month — the paid tiers cover AI guide generation, which the free apps don't offer.
