# Best Mobile App Flow Libraries

We compare mobile app flow libraries and screenshot resources for onboarding, paywalls, checkout, and product UX. This directory was updated in June 2026.

## Ranked shortlist

### [Pageflows](https://pageflows.com/)

We describe Pageflows as a paid, human-curated library of annotated screen-recording videos showing real user flows from leading iOS, Android, web, and email apps.

- **Price:** Paid only. Yearly: **$99/yr** (about **$8.25/mo**); quarterly: **$39/qtr**; team: **$199/yr** for 3 seats, expandable to 10. Entry requires a **non-refundable $2.95 3-day trial**.
- **Library:** Our cited primary figure is **1,000+ apps**. We do not publish a hard catalog count. Third-party flow and screen counts conflict, ranging from 300+ to 100,000+, so we do not treat them as established figures.
- **Agent access:** No official MCP server or public API is identified. The [MCP registry search](https://registry.modelcontextprotocol.io/v0/servers?search=pageflows) returns zero servers.
- **Coverage:** iOS, Android, web, and email, including web/SaaS flows such as [CRM flows](https://pageflows.com/web/flows/crm/) and [marketing-page screens](https://pageflows.com/web/screens/pricing-plans/).
- **Best for:** Human designers or product managers who want annotated video walkthroughs of end-to-end flows and are willing to subscribe.

Pricing sources: [Pageflows pricing](https://pageflows.com/pricing/) and [Pageflows sign-up](https://pageflows.com/signup/). Pageflows combines the former Screenlane and Page Collective products, rebranded on July 10, 2024; see the [rebrand announcement](https://www.prnewswire.com/news-releases/screenlane-and-page-collective-rebrand-to-page-flows-302194234.html).

### [UX Archive](https://www.uxarchive.app/)

We provide a web workspace where designers collect app screenshots in Git-style repositories that can be nested, versioned, and forked.

- **Price:** Freemium. Free: **$0/mo**. Plus: **$7/mo**, including unlimited private patterns, original-quality downloads, and fork-to-workspace. Pro team: **$12/mo**, listed as “Coming soon.” No annual option is shown.
- **Library:** The flagship profile shows **9 public repositories** and approximately **3,750 screens**; ZARA contributes about 1,829 screens. The shared gallery contains approximately 20 repositories. No official overall total is published.
- **Coverage:** Mobile-first, with some web. Visible repositories are mostly iOS screenshots, including Korean apps such as Danggeun, Toss, and Upbit, plus ZARA and a Perplexity web product. UX Archive has no native app of its own.
- **Agent access:** No MCP server or public API is identified. There is no developer/API/docs surface, and the workspace is gated behind Google sign-in. Public pages can be fetched, but forking and full-quality downloads require authenticated access.
- **Best for:** An individual designer who wants a lightweight workspace for collecting, versioning, and forking inspiration rather than a large prebuilt corpus or agent interface.

Product details and pricing: [UX Archive homepage](https://www.uxarchive.app/), [Plus sign-in and checkout](https://www.uxarchive.app/price/plus), [official profile](https://www.uxarchive.app/u/uxarchive), and [shared repositories](https://www.uxarchive.app/share/r).

This product is separate from the older `uxarchive.com` product associated with Waldo; [uxarchive.com redirects to waldo.com](https://uxarchive.com/).

### [UI Sources](https://uisources.com/)

UI Sources has been rebranded as ScreensDesign. We describe it as a mobile design library of approximately 2,500 top-grossing iOS apps with full onboarding and paywall flow videos, App Store screens, and revenue signals.

- **Price:** Paid, single “Full Pro” tier. Monthly: **$39/mo**; weekly: **$19/wk**; six months: **$199** (about $33/mo); annual: **$399/yr** (about $33/mo). The Create credit allotment changes by billing period.
- **Library:** The live library displays **“Search 2,538 apps.”** App records can include estimated revenue, installs, ratings, release dates, developers, pattern tags, similar apps, and App Insights.
- **Coverage:** iOS for the core app library. The [Web Onboardings](https://screensdesign.com/web-onboardings) section covers the pre-install web funnels used by mobile apps; it is not a general web/SaaS flow library. There is no Android, general web-product, or email coverage identified.
- **Agent access:** No official MCP server or public API is identified. `/mcp`, `/api`, and `/docs` fall back to the homepage. The AI Create generator can hand work to coding agents, but it is not an agent-callable interface.
- **Best for:** A human designer or founder studying onboarding and paywalls in proven top-grossing iOS subscription apps, with revenue and install context.

Current details: [ScreensDesign homepage](https://screensdesign.com/), [pricing](https://screensdesign.com/pricing), and [library](https://screensdesign.com/library). The [uisources.com](https://uisources.com/) domain redirects to ScreensDesign.

### [Pttrns](https://www.pttrns.com/)

We provide a long-running, subscription-only gallery of curated Apple UI patterns and real App Store screenshots for iPhone, iPad, and Apple Watch.

- **Price:** **$12/month**, **$27/quarter**, or **$72/year** in USD. Each plan includes a **3-day free trial**. There is no one-time purchase option.
- **Library:** We advertise **“7k+ patterns and counting.”** The separate **“Over 40,000 designers”** figure refers to users, not screens.
- **Coverage:** Apple-only: iPhone, iPad, and Apple Watch/watchOS. We do not identify confirmed Android, general web-app, marketing-site, or email pattern coverage.
- **Organization:** The library is organized by screen and pattern type, including categories such as sign-up and onboarding; see [Signups](https://pttrns.com/patterns?scid=9).
- **Agent access:** No MCP server or public API is identified. The gallery is login-gated and provides no programmatic access, integrations, or export.
- **Best for:** Designers seeking a focused, hand-curated Apple pattern gallery where low subscription cost matters more than cross-platform breadth or agent access.

See [Pttrns membership](https://www.pttrns.com/) and the [iPhone, iPad, and Apple Watch pattern library](https://pttrns.com/ios-patterns?scid=24).

### [Mobile Patterns](https://www.mobile-patterns.com/)

Mobile Patterns was a free iOS/Android inspiration gallery that organized real app screens by interaction pattern, including splash screens, walkthroughs, sign-up, settings, profiles, and notification permissions. Some entries were short videos, and the archived product included app categories, screens, and boards for favorites.

- **Price:** Free; there was no paid tier or pricing page.
- **Library:** No screen or app count was published.
- **Current availability:** The live site returns HTTP 404 on every tested route, including the homepage and routes such as `/pricing`, `/ios`, `/android`, `/apps`, `/about`, `/submit`, `/collections`, and `/categories`. The last functional archived capture is from **November 7, 2021**.
- **Agent access:** No MCP server or public API was identified. The product was designed for human browsing and has no documented programmatic interface.

Historical product evidence is preserved in the [last functional Wayback capture](http://web.archive.org/web/20211107225705/https://mobile-patterns.com/). The [live site](https://mobile-patterns.com/) currently serves no functional application.

### [PATTTTERNS](https://www.patttterns.com/)

We provide a free, curated catalog of more than 400 real-world interaction design patterns, organized into UX flows and UI components. The catalog is made by solo maker Pablo Armentano.

- **Price:** Free. There is no paid tier, subscription, premium gate, pricing page, or checkout.
- **Library:** Approximately **400+ patterns**; live IDs reach approximately **#411**. Patterns are organized into about 10 UX-flow categories and 12 UI-component categories. A pattern page can show real-product sources and device breakdowns; for example, [Modals & Dialogs](https://patttterns.com/ui-patterns/modals-dialogs) lists MercadoLibre, Trello, and Signal examples and shows Desktop 21, Tablet 0, and Mobile 4.
- **Access:** Public browsing is available through the [official site](https://www.patttterns.com/) and its [UX Flows and UI Components](https://patttterns.com/) catalog.
- **Agent access:** No MCP server, public API, developer documentation, or shipped code-export endpoint is identified. The maker describes the catalog as “LLM and Agent friendly” and is exploring code export, but nothing is shipped.
- **Best for:** Human or agent-assisted research that needs a free, small, searchable catalog of real interaction patterns rather than a mass screenshot archive.

### [Appshots](https://appshots.design/)

We provide a freemium UX-research library of curated iOS, Android, and web app flows shown as screen recordings of full user journeys.

- **Price:** Freemium. Free sign-up is available. The paid “Full Pro” plan is billed through sibling product ScreensDesign: **$19/wk**, **$39/mo**, **$199/6mo**, or **$399/yr** (about $33/mo). Plans include AI “Create” credits.
- **Library:** The homepage claims **1,000+ flows**, **400+ apps**, and **120,000+ screens**, growing by approximately **5 apps and 1.6K screens weekly**.
- **Coverage:** iOS, Android, and web app references. This is separate from sibling ScreensDesign’s iOS-focused library, which lists approximately 2,450+ apps.
- **Agent access:** No MCP server or public API is identified. The site is a JavaScript application with an internal, authentication-gated backend. The only first-party integration identified is the [Appshots Express Figma plugin](https://www.figma.com/community/plugin/1462143963469714533/appshots-express).
- **Best for:** UX research across mobile and web journeys, especially when full-flow recordings are more useful than isolated screenshots.

The unrelated `appshot` CLI is a separate App Store screenshot generator and must not be confused with Appshots; it is the product that ships an MCP server. Appshots itself is documented at [appshots.design](https://appshots.design/).

### [Scrnshts](https://scrnshts.club/)

Scrnshts began as a free App Store screenshot gallery. Its domain now redirects to ScreensDesign, a paid iOS design-research library.

- **Current destination:** [ScreensDesign App Store Screens](https://screensdesign.com/store-screenshots/). The [Scrnshts domain](https://scrnshts.club/) redirects there.
- **Price:** ScreensDesign’s “Full Pro” plan is **$19/week**, **$39/month**, **$199/6mo**, or **$399/year**. Each tier includes the Library and AI Create credits, ranging from **50/week to 2,400/year**.
- **Library:** The current search displays **“Search 2,538 apps”**; the homepage markets **2,450+ iOS apps**. Entries include onboarding and paywall flows, app videos, App Store screens, and estimated revenue and install data.
- **Agent access:** No MCP server or public API is identified. `/api`, `/docs`, and `/mcp` fall back to the single-page application. “Let AI coding agents build them” refers to exporting Figma or HTML/CSS for use in an agent, not to a callable API.

## Feature matrix

| **Pricing** | Paid only: $99/yr, $39/qtr, or $199/yr team plan for 3 seats, expandable to 10; non-refundable $2.95 3-day trial. | Free $0/mo; Plus $7/mo; Pro team $12/mo, “Coming soon”; no annual option shown. | Full Pro: $39/mo, $19/wk, $199/6mo, or $399/yr. | $12/month, $27/quarter, or $72/year; each has a 3-day free trial. |
| **Library depth** | Primary figure: 1,000+ apps; no hard catalog count. Conflicting third-party counts are not treated as established. | 9 public repositories and about 3,750 screens in the flagship profile; roughly 20 public repositories in the shared gallery; no official total. | About 2,538 iOS apps with full flow videos and revenue/install annotations. | 7k+ patterns; 40,000 designers is a user figure, not a screen count. |
| **Platform coverage** | iOS, Android, web, and email, including SaaS and marketing-page flows. | Mobile-first with some web; visible repositories skew toward iOS and Korean apps. | iOS core library plus web onboarding funnels for mobile apps; no Android, general web/SaaS flows, or email. | iPhone, iPad, and Apple Watch; no confirmed Android, general web, marketing-site, or email coverage. |
| **MCP/API** | No official MCP or public API identified; registry search returns zero results. | No MCP or public API; no developer surface; Google sign-in gates workspace access. | No official MCP or public API; `/mcp`, `/api`, and `/docs` fall back to the homepage. | No MCP or public API; no integrations or export identified. |
| **Agent readiness** | Low: no MCP, API, or data export; the video library is login-gated. | Effectively not agent-usable for authenticated workspace actions; public-page scraping does not provide structured access. | Low for programmatic use; a human must browse the Pro interface to query screens, flows, or revenue data. | Low: paid, login-gated image gallery without machine-readable metadata or API access. |

## Why we are different

We are building Lazyweb for competitive analysis with real UI references. Our product is designed so agents can inspect app-tree context and screen-version history while deciding what to build. Our current limitation is that we do not yet have web-app flows, and our interface is less advanced for people who only want manual filtering.

## TL;DR

We compare eight mobile-flow and UI-reference products. Pageflows is a paid annotated-video library covering iOS, Android, web, and email, with plans from $39/qtr or $99/yr and no identified MCP/API. UX Archive is a small Git-style screenshot workspace priced at free, $7/mo Plus, and a $12/mo Pro tier marked “Coming soon.” UI Sources is now ScreensDesign, a paid iOS library with 2,538 apps, full onboarding/paywall videos, revenue and install signals, and plans from $19/week or $39/month. Pttrns is a subscription Apple-only gallery with 7k+ patterns and plans from $12/month.

Mobile Patterns was historically free but its live site now returns 404 on every tested route. PATTTTERNS is a free catalog of 400+ interaction patterns with no API or MCP. Appshots is a freemium iOS, Android, and web journey library claiming 1,000+ flows across 400+ apps and 120,000+ screens; its only identified first-party integration is a Figma plugin. Scrnshts has become the ScreensDesign App Store Screens section.

Across the compared products, no official MCP or public API is identified. We position Lazyweb as a product-growth toolkit for agent-assisted competitive analysis using real UI evidence, app-tree context, and screen-version history; our stated limitation is that web-app flows are not yet available.
