Paintstorm Studio: $19 for a Professional Brush Engine That Deserves More Attention

Paintstorm Studio is the digital painting world's best-kept secret. For $19 (less than a month of most software subscriptions), you get a desktop painting application with a brush engine that rivals tools costing five times as much, a real color mixer palette that simulates paint mixing on a physical palette, and support for importing Photoshop brushes. The iOS version at $9.99 adds Apple Pencil hover support and runs on iPad.

The catch: almost nobody knows about it. The community is small, tutorials are scarce, and the desktop version has not received a major update since version 2.50 in April 2023. The iOS version received a minor Apple Pencil fix in February 2026, confirming the developer is still around, but the update cadency is slow. This is a niche product maintained by a small independent developer, and you need to know that going in.

The Brush Engine: Deep Enough for Professionals

Paintstorm's brush engine is the reason to buy this app. The customisation depth is exceptional, with control over brush shape, texture, blending behavior, pressure response, tilt response, and dozens of other parameters. Bristle brushes of any form and kind are supported, and the engine simulates how individual bristles interact with the canvas surface.

The stroke post-correction system is a standout feature. Unlike most apps that only correct stroke thickness after drawing, Paintstorm lets you adjust any brush parameter after the stroke is made. Draw a line, then change its opacity, color, texture, or shape without redrawing. This is a workflow advantage that even Procreate does not offer.

Dirty brush mode simulates how a real brush picks up and mixes colors as you paint. After loading a brush with one color and painting over another, the brush carries residual paint that mixes with the new stroke. This produces the organic, unpredictable color transitions that make traditional painting feel alive and that most digital brushes completely fail to capture.

The engine also supports multithreaded stroke calculation (Windows only), which keeps strokes smooth even with large brushes on huge canvases. On macOS and iOS, performance is good but not as optimized for extreme canvas sizes.

The Mixer Palette: Mixing Colors Like Real Paint

The Mixer Palette is Paintstorm's most distinctive feature. It provides a virtual mixing area where you blend colors before applying them to the canvas, simulating how real paint mixes on a physical palette. You pick up a color with your brush, mix it with another color on the palette, and apply the mixture to your canvas.

For artists transitioning from traditional to digital painting, this workflow is immediately familiar. It is the same process you use with oils or acrylics: load the brush, mix on the palette, apply to canvas. Most digital painting apps skip this step entirely, relying on color pickers and blend modes instead. Paintstorm brings the physical mixing workflow to digital, and for painters who think in terms of mixing rather than selecting, it changes how the app feels.

Rebelle and Corel Painter also have mixer palette features, but both cost significantly more. At $19, Paintstorm is the cheapest way to get this workflow.

Photoshop Brush Compatibility

Paintstorm supports importing Photoshop ABR brush files, which means you can bring your existing Photoshop brush library into the app. This is a significant advantage for artists migrating from Photoshop who have invested years in building custom brush collections.

The import is not perfect. Complex Photoshop brushes with multiple textures and dual-brush configurations may not translate perfectly, but standard brushes import cleanly and work as expected. Given that Infinite Painter does not support ABR import at all and Krita requires manual conversion, Paintstorm's direct import is a practical advantage.

The iOS Version: iPad Painting at $9.99

The iPad version of Paintstorm Studio costs $9.99 and includes Apple Pencil support with pressure, tilt, and direction tracking. The 2.50 update added Apple Pencil Hover support (showing a preview of the brush before touching the canvas) and double-tap support for switching tools.

The iOS version is functionally close to the desktop version, with the same brush engine, mixer palette, and PSD/ABR support. The interface adapts to touch, though it is less polished than Procreate's gesture-driven interface. For $9.99, it is one of the cheapest professional-grade painting apps on iPad, though the small community means you will not find the tutorial ecosystem that Procreate has.

The Honest Concerns

The desktop version has not been updated since April 2023. The iOS version received a minor fix in February 2026, which confirms the developer is still active, but the update cadency is concerning for a tool you might build a professional workflow around. If you need reliable, frequent updates, Krita (free, actively developed) or Procreate ($12.99, regularly updated) are safer bets.

The community is very small. Finding tutorials, troubleshooting answers, or community-created brush packs requires more effort than for mainstream apps. The Paintstorm forums exist but are low-traffic, and YouTube tutorials are scarce compared to the thousands available for Procreate or Clip Studio Paint.

The interface is functional but unpolished. It looks like a tool built by a developer who prioritized the brush engine over visual design. Panels can be customized and arranged, but the default layout and visual style will not win any design awards.

Insider Tips

• Import your Photoshop brushes. Use File > Import Brushes to load ABR files. Test them on a scratch canvas first, as complex brushes may need parameter adjustments.
• Use the Mixer Palette for skin tones. Mixing base skin tone colors on the palette before applying them produces more natural variation than picking colors individually from the color wheel.
• Bind brush parameters to perspective. Paintstorm can bind brush size and opacity to perspective distance, so strokes automatically thin out as they recede toward a vanishing point. This is useful for environment concept art.
• Create brush presets. The 2.50 update added brush presets, letting you save multiple configurations for each brush. Set up presets for your most-used brushes to avoid re-configuring parameters each session.

Competitor Comparison

| Feature | Paintstorm Studio | Krita | Procreate | |---------|------------------|-------|-----------| | Price | $19 desktop / $9.99 iOS | Free | $12.99 (iPad) | | Mixer palette | Yes | No | No | | Photoshop ABR import | Yes | Requires conversion | Yes | | Brush customisation depth | Very high | Very high (9 engines) | High | | Update frequency | Slow | Regular | Regular | | Community size | Very small | Large | Very large | | Animation tools | No | Yes | Basic (Animation Assist) |

Final Verdict: Who Is This Actually For?

Paintstorm Studio is for digital painters who want a deeply customisable brush engine and a real color mixing workflow without paying subscription fees or even $50 for a one-time purchase. At $19, the value is undeniable if the brush engine suits your style.

The risk is the slow development pace and small community. If you are building a professional workflow that depends on ongoing updates, bug fixes, and community support, this is a gamble. If you are a hobbyist or professional who found a brush configuration that works and just wants a stable, affordable painting tool, Paintstorm delivers.
