FlowSnap

Overview

FlowSnap turns app screenshots into visual sitemaps and user-flow diagrams, aimed at product managers, UX designers and indie developers. It is best suited to people who want to map an app from screen captures and export the result in several formats. Its strongest case is a focused visual workflow with local storage and optional AI; the free plan’s three-project cap and PNG watermark make it less suitable for ongoing, polished client work.

Key features

The infinite canvas brings imported screens into one workspace, with panning, pinch zoom from 10% to 200%, color-tagged cards and text annotations. A project can batch import up to 50 screenshots from a photo library or Google Drive, which gives a useful starting point for mapping a substantial flow without placing every screen individually.

Solid or dashed connectors, custom connection colors and transition labels let teams distinguish paths and clarify what happens between screens. Flow templates provide a starting structure, while exports in PNG, PDF, SVG, JSON and Markdown cover both visual sharing and structured output. The free plan includes core canvas features, but its PNG export carries a watermark; clean PNG, PDF and SVG exports require Pro.

Optional AI can analyze screenshots, suggest connections and produce a Markdown sitemap summary. It requires the user’s Claude API key, so it is an opt-in aid rather than an included, self-contained service. Screenshots sent for AI analysis go to Anthropic’s Claude API using that key. Project data is saved locally and can optionally sync to a FlowSnap folder in the user’s Google Drive; FlowSnap says it does not store project data.

Pricing

Free — 0.00 USD per free. Includes core canvas features and up to three projects. It is a sensible way to try the mapping workflow or keep a small personal project, but the project cap and watermarked PNGs constrain regular use and presentation-ready exports.

FlowSnap Pro — Monthly — 2.99 USD per month. Adds unlimited projects, PDF export, watermark-free PNG, SVG export and priority AI features. It fits users who need clean exports or manage several projects but prefer a recurring plan.

FlowSnap Pro — Lifetime — 19.99 USD per once. Includes the same listed Pro features without a monthly charge. For someone who expects to use FlowSnap over time, that is a low one-time route to unlimited projects and clean exports; readers who only need occasional mapping can stay on Free.

Platforms

FlowSnap supports Android, iOS and macOS. The App Store specifies iOS 13.0 or later and macOS 10.15 or later. Google Drive import and sync are supported, alongside photo-library imports.

Who it's for

FlowSnap is a good fit for product managers, UX designers and indie developers who already have app screenshots and want to turn them into annotated, shareable maps. Its import cap and multiple export formats suit work that moves from screen inventory to a documented flow. It is a weaker fit for people who need more than three projects without paying, require unwatermarked free exports, or want AI analysis without bringing their own Claude API key.

Pros and cons

• Pros: Batch import of up to 50 screenshots per project speeds up mapping larger screen sets.
• Pros: Labeled, styled connections and text annotations make the relationships between screens explicit.
• Pros: PNG, PDF, SVG, JSON and Markdown exports give users several ways to share or reuse project output.
• Pros: Local project storage with optional Google Drive sync gives users control over where project data is kept.
• Cons: Free users are limited to three projects and get a watermark on PNG exports, so the free tier is restrictive for ongoing or polished work.
• Cons: AI features require a personal Claude API key and send screenshots to Anthropic, which may not suit users who want AI without that setup or data flow.

Alternatives

User Flow Software is a broader directory for readers who want to compare tools across the category.

• Marvel may suit readers who want a web option alongside Android, iOS and API support, or prefer a free plan capped at one user and one project before considering its Pro plan.
• Zeplin Flows is worth considering for Linux, Windows or web users, or teams interested in its free plan’s unlimited members and weekly AI review and organization allowances; that tier has one project, 100 screens and no Flow Boards.
• Rheo may be the better fit for Android or iOS users looking for an app plan that includes one app, one seat and 400 MAU, rather than a screenshot-to-map workflow.
• BenchCanvas is an option for web or browser-extension users who want comments and annotations alongside AI analyses and PDF/PNG export in its Pro plan.
• Figr may suit people looking for a web, extension or API option with Figma export on its free plan.
• Wireflow is the alternative to consider if MIT licensing, open-source development or self-hosting is important.
• Sketchflow.ai is another freemium option for Android, iOS and web.
• Slickplan may suit readers seeking a web-based option with API support and a free trial.

Verdict

Choose FlowSnap if your work starts with app screenshots and you want a clear, exportable map without paying much to remove project and watermark limits. The lifetime Pro plan is compelling for sustained use, and local storage with optional Drive sync is a practical strength. Look elsewhere if the free tier must support larger project libraries or clean exports, or if you need AI analysis without supplying a Claude API key.
