Oil-painting app — market & competitive research (first pass)

Desk research done 2026-09-23. Everything here is secondary-source and needs the primary checks listed in §6 before any money or year of work is committed to it. Numbers from analyst press releases are marked (low trust).

1. The single most important finding

The gyroscope-relit impasto idea has already shipped once, on iPad, and did not take.

Psykopaint (Psykosoft) released an iPad app around 2014–15 that used the device gyroscope to relight a painted surface so that thick strokes "catch the light" as you tilt — marketed explicitly on Monet / Van Gogh impasto, and covered by Vice, TNW and Cult of Mac at the time ("the closest thing to holding a real canvas in your hands"). It survives mainly as a web photo-to-painting toy; there is no sign of an actively developed iPad product.

Do not treat this as fatal — treat it as the central question of the investigation. Plausible reasons it did not become the category, all of which are testable:

It was a photo-to-painting filter, not an instrument. You fed it a photograph and it stroked it for you. Painters were never the customer.
There was no paint simulation underneath — the relighting sat on a generated texture, so the thickness was not something you made, it was something applied.
It predates Apple Pencil (2015), ProMotion, and M-series compute. The hardware that makes a real paint sim playable did not exist yet.
The output was still a flat image — the relighting lived only inside the app, so nobody who saw the result ever experienced the effect.

The wedge in the brief is the inverse of all four. If the investigation cannot articulate why those four differences change the outcome, the wedge is not a wedge.

2. Competitive landscape — what is actually on sale

Product	Platform	Price	Paint physics	Position
Procreate (Savage Interactive, AU)	iPad	$12.99 one-time; Pocket $5.99; Dreams $19.99	None — dab-stamp brush engine	The default. Repeatedly #1 paid iPad app, millions of copies. Buy-once forever, a deliberate stand against subscriptions
Adobe Fresco	iPad / iPhone / Win	Free (went fully free at its 5th anniversary, all 1,000+ brushes incl. Live Oils)	Live Oils: genuine thick paint, brush pickup, on-canvas mixing	Free funnel into Creative Cloud. Apple Pencil Pro support. The nearest iPad competitor by far
ArtRage Vitae (Ambient Design, NZ)	iPad $4.99 / Android / Mac	~$4.99 mobile	Real: tracks paint load, wetness, canvas tooth, bump-lit paint	The original natural-media painter. Lightly maintained (mobile v1.1.5, 2023). Sells the exact promise, quietly
Rebelle 7 (Escape Motions, SK)	Win / macOS only	$89.99 Standard / $149.99 Pro	Best in class: oil & acrylic impasto with per-pixel height, real watercolour, Mixbox spectral pigment mixing	The simulation frontier — and proof people pay $150 for physics
Clip Studio Paint	All	Subscription / perpetual	Limited	Comics/illustration, not paint
Psykopaint	Web / (ex-iPad)	—	None	See §1

The price anchor is brutal and must be confronted, not wished away: the best-funded competitor is free, and the category default is $12.99 once. Yet Rebelle sells a $149.99 desktop product on physics alone. The strategic question is whether an iPad app can be sold as an instrument (priced like a good brush set, $30–60) rather than as an app.

3. Market size (low trust — vendor reports, wide disagreement)

"Art app market": $3.8 B in 2026 → $12.55 B by 2035, 14.2% CAGR.
"Digital illustration app market": $11.58 B in 2025 → $27.62 B by 2035, 9.08% CAGR.
Broader digital art market: ~$15 B in 2026 → $67 B by 2040. North America ~36% share.

These are not decision-grade. The only number worth building a plan on is bottom-up: iPads sold with Pencil support × share who paint × observed conversion at $X. Build that model (§6).

4. Positioning gaps that are genuinely open

Rebelle-class physics at Procreate-class feel, on a tablet. Nobody occupies this. Rebelle is desktop and heavy; Fresco is free but shallow on lighting; ArtRage is right but dormant.
The painting as a relightable object. Every competitor's export is a flat raster. Nobody ships height/normal maps, a relight share, an AR hang, or a relief print. This is the part of the wedge that no incumbent can copy without re-architecting their document format.
Anti-AI, pro-hand. Procreate's August 2024 "AI is not our future" stand (CEO James Cuda: "I really f**ing hate generative AI") drew overwhelmingly positive artist response, while Adobe's Firefly push and Wacom's AI-generated marketing both drew backlash. A product whose entire pitch is physical matter made by your hand* is on the right side of this by construction. It is a real, proven marketing position — but it is now a crowded one, and claiming it requires meaning it (see the brief's non-goals).
Hardware showcase. Apple Pencil Pro (barrel roll, squeeze, haptics) plus gyroscope relighting plus 120 Hz plus P3/HDR gloss is exactly the kind of app Apple features and gives Design Awards to. Editorial featuring is a distribution channel worth designing for deliberately, not hoping for.

5. Marketing assets the product generates for free

The demo is the ad. A 10-second clip of a phone tilting while raking light crosses a thick stroke is self-explanatory, needs no voiceover, and works natively on TikTok/Reels/YouTube Shorts. Test this early: cut the clip from spike 1 and see whether it travels before building.
A relit share link means every painting a user shares is a product demo for a viewer who has never heard of the app, on hardware they already hold.
A physical relief print of a user's painting is a press object and a gift-shop-grade proof.
Channels: iPad-art YouTube (Brad Colbow, Jazza-tier reviewers), r/ProCreate and r/learnart, plein-air and atelier painting communities (who are not currently digital customers and are the most interesting beachhead), art schools.

6. What this research cannot answer — close these before committing

Why did ArtRage stall? It has had the right product for twenty years at $4.99. Talk to users, read reviews, work out whether the market is small or the execution was.
Bottom-up TAM. Pencil-capable iPad install base × painting-app attach rate × price.
Willingness to pay for an instrument at $30–60 one-time vs $12.99 vs free-with-pro-tier. Run a real price test (landing page + pre-order intent), do not survey.
Does the relight clip travel? Post spike 1's footage. Views are the cheapest possible validation of the entire wedge.
Do real oil painters want this at all, or is the digital-painting buyer a different person (illustrators, concept artists) who does not care about impasto? This determines everything about positioning and may be the real risk.
Mixbox licensing terms and cost (Secret Weapons) vs. implementing Kubelka–Munk ourselves.
Fresco's roadmap and whether Procreate has ever shipped or teased surface lighting.
