ProtoSketch

ProtoSketch is vector graphics design software for work including web and app graphics, logos, icons, print, illustration, UI, and UX. Its tools include vectors, icons, fonts, UI elements, shapes, smart guides, object snapping, an adjustable grid, and alignment and distribution commands. For styling, users can apply fills, strokes, gradients, blending modes, and opacity, with RGB sliders, color wheels, and hex input. The app supports path drawing and editing, layers and groups, and operations such as divide, exclude, minus front, unite, and intersect. It exports PDF, imports and exports PNG and JPG, and supports SVG data exchange; SVG import is described as planned. On iOS, Dropbox can import documents and images, and “Open in…” is available. ProtoSketch Lite costs nothing, allows up to five documents, locks some libraries, and limits export to social shares and ProtoSketch files. ProtoSketch is available on iOS, while the Mac version is in development. The FAQ describes the product as subscription-free without stating an amount. Interactive prototypes and team collaboration are not available.

ProtoSketch provides a broad set of vector drawing and layout tools for iOS design work. Check the Lite document and export restrictions, and note that the Mac version remains in development.

ProtoSketch suits designers creating vector artwork for web, mobile, logos, icons, print, UI, or UX on iOS. Its Lite plan may fit users who can work within a five-document cap and restricted exports.

ProtoSketch is a vector graphics app for designers creating illustrations, logos, icons, and interface assets on iOS. It suits solo users who want detailed path and styling controls; its five-document Lite cap and narrow export options make it less suitable as a production workspace.

Overview

ProtoSketch spans web, mobile, UX, UI, product, print, and marketing design, with tools for both basic and complex shapes. Its combination of path editing, shape operations, and layout controls makes it a capable option for individual vector work. It is not a prototyping or team-design app: interactive prototypes and collaboration are not supported.

Key features

Pen and pencil tools create paths, and users can edit individual points. Divide, exclude, minus front, unite, and intersect operations support more involved shape construction. Layers can be locked or adjusted for opacity, and groups help organize artwork. Together, these tools suit illustration and asset creation, though they do not provide a shared design workflow.

Smart guides, object snapping, an adjustable grid, and alignment and distribution commands help keep elements in position. Styling includes fills, strokes, gradients, blending modes, and opacity, with RGB sliders, color wheels, and hex input for color selection. These controls are useful when a design needs precise placement and deliberate color treatment.

File support is mixed. ProtoSketch exports PDF, imports and exports PNG and JPG, and supports SVG exchange; SVG import is planned for a future version. Dropbox import is available on iOS, while iCloud syncing across iPhone, iPad, and Mac remains planned. “Open in…” functionality offers another way to move files between apps.

Pricing

ProtoSketch Lite is free. It allows up to five documents, locks some libraries, and limits export to social shares and ProtoSketch files. That is enough for trying the drawing tools or keeping a small set of personal projects, but the document ceiling and export restrictions are meaningful obstacles for ongoing client or production work.

The FAQ describes ProtoSketch as subscription-free but does not give an amount for a paid plan. The Mac version is in development, with an invitation to sign up for beta; no current Mac availability makes it a choice for iOS work rather than a cross-platform workflow today.

Platforms

ProtoSketch is available for iOS, with a Mac version in development. The FAQ describes planned iCloud syncing across Mac, iPad, and iPhone, but that is not a current cross-device workflow. The product also has no interactive prototypes or real-time collaboration, so teams needing shared editing or linked interactions should look elsewhere.

Who it's for

ProtoSketch is best suited to individual designers who need vector drawing and layout tools on iOS, particularly for illustrations, logos, icons, and UI assets. Lite can work for small personal projects or initial exploration. Designers who depend on broad export access, larger document libraries, Mac availability, prototyping, or team editing should choose a different tool.

Pros and cons

• Pros: Path editing and boolean-style shape operations support detailed vector construction, while layers, groups, snapping, and alignment tools help manage and place artwork precisely.
• Pros: PDF export, PNG and JPG import/export, and SVG exchange cover common ways to share or reuse artwork, and Dropbox import is available on iOS.
• Cons: Lite stops at five documents, locks some libraries, and restricts export, limiting its usefulness for a growing or delivery-heavy workflow.
• Cons: The Mac version and iCloud sync are still planned or in development, and the app has neither interactive prototypes nor team collaboration.

Alternatives

Vector Graphics Software and Prototyping Software roundups are useful starting points for comparing tools by category.

• Linearity Curve is worth considering for an iOS and Mac alternative with a free plan that includes 250 lifetime credits, one basic brand kit, and 5GB of cloud storage.
• Amadine may suit iPad and iPhone users who want a fully operational free version, while exporting, printing, and image tracing require a purchase.
• Dotgrid is a free, open-source option for readers who want software with source code licensed under MIT and support across Android, Linux, Mac, and Windows.
• Gusta Draw is a free choice across Android, iOS, and web, with drawing tools, effects, starter designs, and SVG, PNG, and PDF exports included.
• EazyDraw offers a no-time-limit Basic Mode, but it is limited to one layer and 32 graphics.
• Boxy SVG is another option for readers comparing vector software across a broad set of platforms.
• Inkpad is an iOS alternative with a 30-day free trial for its monthly plan, then $1.99 per month.
• Vector Ink is an alternative available on iOS, Mac, and web.

Verdict

The core toolkit is broad, but Lite’s five-document limit and restricted exports make it a poor fit for sustained production, while the unfinished Mac version and lack of collaboration rule it out for teams seeking a shared cross-platform workflow.
