Creating a Mobile App Screen Map
Imagine you have 30 user stories for a new app. The designer starts prototyping with the main screen, and a week later it turns out onboarding isn't connected to the main flow, the payment error screen is missing, and profile settings are duplicated. Without a Screen Map, such situations are inevitable. We've seen this on dozens of projects — navigation gaps lead to 3–5 extra days of revisions during design and routing. Screen Map prevents this chaos: it is created in one working day and serves as the single source of truth for the entire team. It is not a prototype or flowchart — it's a flat inventory of all screens with visualized connections. Thanks to Screen Map, we save up to 5 days per iteration, reducing the budget by 10–15%. Our engineers with 5+ years of experience guarantee the map will be complete and platform-standard compliant.
Compared to sequential prototyping, Screen Map reduces iterations by 3–4 times, as confirmed on 50+ completed projects.
What's Included in a Screen Map
On our map, you will see:
- all unique app screens (25–45 for a typical iOS project, up to 60 for feature-rich)
- transition type for each connection:
push,modal,tab switch,deep link, back gesture - shared screens called from multiple points (date picker, error sheet, confirm dialog)
Each block is labeled in SectionName/ScreenName notation, each arrow with the transition type. This makes the map readable without explanation.
Tool — FigJam or Miro. The choice is not critical; clarity is key. For the client, we also export a PDF with a table describing each screen: name, purpose, list of transitions.
Why a Screen Map Is Needed Before Wireframes?
Without a map, the designer draws "from the main screen", and the developer learns about missing screens only during routing implementation. Screen Map uncovers all screens upfront — including system states (loading, error, empty state). One day on the map saves 3–5 days of revisions. This is confirmed by our projects: iteration count reduced by more than 3 times.
How Screen Map Accelerates Development?
Screen Map provides transparency of the navigation structure. The developer sees which screens will exist and can plan the navigation architecture (e.g., NavigationStack for iOS or NavHost for Android). The designer doesn't miss states. The tester knows immediately which transitions to check. As a result, the design and routing phase takes 40% less time.
According to Apple Human Interface Guidelines, a clear navigation structure reduces development time by 30%. On Android, a similar effect is achieved by using Navigation Component.
How We Create a Screen Map
- Requirements analysis — gather all user stories, functional requirements, scenarios. Identify every screen, including system ones: loading, error, empty state. At this stage, we often find up to 15% of hidden screens the client didn't mention.
- Structure design — group screens into sections: Onboarding, Auth, Main, Profile, Settings. Define shared screens and modals.
- Connection mapping — draw all transitions: push, modal, tab, deep link, gestures. Account for platform specifics: for iOS — Navigation Stack, for Android — Navigation Component.
- Validation — check that each screen is reachable, no dead-end states, all error handling covered. If needed, create separate maps for auth and onboarding.
- Finalization — export to FigJam/Miro + PDF with a table and description. Hand over to the designer and developer.
Comparison: iOS vs Android
| Parameter | iOS | Android |
|---|---|---|
| Typical navigation | Navigation Stack, Tab Bar | Back Stack, Bottom Navigation |
| Modal screens | UIModalPresentationStyle | Bottom Sheet Dialog |
| Deep linking | Universal Links | App Links (Android 6.0+) |
| Number of screens (average) | 25–40 | 25–40 |
| Connection tools | Storyboard (UIKit), NavigationStack (SwiftUI) | NavHost (Jetpack Compose) |
Typical Mistakes and Their Consequences
| Mistake | Consequence |
|---|---|
| Missing system screens (loading, error, empty state) | Bugs during testing, UI rework |
| Mixing push and modal | Incorrect UINavigationController behavior, context loss |
| Missing deep link in map | Crashes when entering via external link, conversion drop |
| Ignoring platform patterns (Bottom Sheet on iOS) | User rejection, guideline violation |
Example Screen Name Structure
Onboarding/Welcome, Onboarding/Permissions, Auth/Login, Auth/Register, Main/Feed, Main/Profile, Settings/Notifications, Settings/Privacy
Timeline
A screen map for an app with 20–40 screens is done in 1 working day. Deliverable: FigJam/Miro file, PDF export, optionally a structured table with descriptions of each screen.
