Mobile app design inspiration becomes more useful when it shows what happens across several screens rather than presenting one polished interface in isolation. A sign up screen is connected to permissions, verification, profile setup, and the first meaningful action inside the app. Subscription design also depends on timing, pricing choices, trial information, and what happens after an offer is dismissed. Studying those connections gives mobile designers more context for their own decisions.

The three websites below approach mobile interface research differently. One concentrates heavily on complete user flows, another organizes thousands of production mobile patterns, and the third provides detailed research into iOS onboarding, subscriptions, paywalls, and app screens. That difference matters because mobile app design includes more than visual styling. Navigation, states, permissions, account creation, monetization, and recovery all compete for limited screen space.

What to Research Before Saving Mobile App Screens

Collecting random screenshots often produces a large reference folder without answering a specific design question. Research is easier to use when it begins with a task. A designer working on onboarding may need to understand where apps ask for an email address, when they introduce permissions, and how quickly the main interface becomes available. Page Flows examples from Airbnb, Strava, and HubSpot show that these steps can be studied as complete sequences rather than separate screens.

A practical mobile research list can start with:

• onboarding and account creation
• login and verification
• navigation and search
• notification and location permissions
• subscription offers and paywalls
• checkout and payment
• empty, loading, error, and confirmation states

1. Page Flows

Designers researching complete mobile journeys can visit Page Flows to study recorded flows and their individual screens. The site includes iOS and Android examples, and many product pages separate a journey into named steps. A HubSpot CRM onboarding recording, for instance, moves through the app listing, welcome screens, signup, email confirmation, notification permission, navigation, and account areas. The same product page also contains additional flows for creating deals, notes, tasks, deleting an account, browsing, and changing settings.

This format is useful when screen order is part of the design problem. The Airbnb onboarding reference includes signup, terms, notifications, and the transition into exploration, while the Strava flow includes profile creation, an upgrade prompt, location permission, sport selection, activity recording, and social discovery. These examples show the surrounding steps rather than removing a screen from its original journey.

Page Flows also includes Android references. Its Deezer example documents login, account details, an upgrade prompt, subscription steps, artist selection, the home screen, notifications, and settings. This makes it possible to research mobile interactions across more than one operating system when relevant to the project.

2. Pttrns

Pttrns takes a pattern focused approach to mobile app design inspiration. Its official site states that the collection contains more than 7,000 curated mobile design patterns and production app interfaces. Research can be filtered through categories covering communication, content, creation, data, media, onboarding, and purchase experiences. More specific filters include signup, walkthroughs, login, search, notifications, checkout, settings, maps, empty states, and permission requests. Favorites and collections are available for organizing references by project, and Pttrns currently states that complete access is free after account creation.

3. Screens Design

ScreensDesign has a narrower mobile focus, with particular attention to iOS apps, onboarding, paywalls, pricing, and subscription behavior. Its current public showcase contains more than 2,600 iOS apps and lets researchers browse app level breakdowns with videos, screenshots, onboarding material, store screens, and conversion context. The site also publishes dedicated mobile design guides covering navigation, forms, filters, dialogs, permissions, feedback, empty states, onboarding, and paywalls.

The subscription research is especially detailed. Its 2026 paywall collection examines recorded in app experiences and considers when an offer appears, how plans are presented, how trials are explained, and what happens around the purchase decision. The examples are connected to recorded journeys, which allows a paywall to be reviewed alongside the steps that led to it.

Individual app pages can also contain chapters for multiple interactions. One Aesthetic app recording, for example, separates onboarding, subscription, theme customization, editing, saving wallpapers, widget creation, AI features, and settings across more than one hundred captured screens. This gives researchers a way to inspect the wider app instead of focusing only on its opening sequence.

ScreensDesign is therefore particularly relevant when monetization is part of the mobile product. The library currently centers on top grossing subscription apps and highlights onboarding, pricing, paywalls, growth loops, and retention.

Which Mobile Design Website Fits Which Task?

The best choice depends on the research question rather than the size of the library. These three resources overlap in some areas, but their structures lead to different workflows.

• Page Flows: useful for studying complete iOS and Android journeys and seeing the exact order of screens.
• Pttrns: useful when research starts with a specific mobile pattern or UI category.
• ScreensDesign: useful for detailed iOS research involving onboarding, subscriptions, pricing, paywalls, and monetization flows.

A designer building an account creation journey may get more value from following several complete flows. Someone deciding how a filter or empty state should work may prefer a pattern based library. A subscription app team may need to examine onboarding and payment together. The reference source should follow the problem being solved.

Better Mobile Inspiration Starts With Comparison

One reference can provide an idea, but several references make differences easier to see. If three apps request notification access at different moments, the useful finding is not that one screen looks better. The important question is what happened before the request and what benefit the user had already seen. Recorded onboarding examples show that permission requests can appear at noticeably different points within the larger journey.

The same method works for subscriptions. A paywall can follow account creation, personalized questions, feature discovery, or an attempt to access paid content. ScreensDesign documents multiple approaches where the preceding context changes how the offer is introduced.

Navigation deserves the same treatment. A tab bar, menu, search screen, or settings page should be studied as part of the tasks surrounding it. Pttrns separates these patterns into searchable categories, which makes focused comparison easier.

Good mobile app design research therefore starts with a clear question and several real implementations. References become evidence for a design decision rather than decoration for a mood board. A complete flow can explain sequence, while a pattern collection can show recurring solutions across many products.

This also reduces the temptation to copy a single interface too closely. Several references reveal which ideas appear repeatedly and which belong to one particular product. That distinction gives designers more room to build an interaction that fits their own users and product constraints.
