How to write a PRD for a mobile app feature (with examples)

QUICK ANSWER

Mobile PRDs have unique requirements that web PRDs miss: offline behavior, notification permissions, OS-level constraints, and platform parity decisions. Here's the complete template.

Mobile PRDs require three sections that web PRDs don't: offline behavior, platform specificity (iOS vs. Android), and OS-level permission flows. Missing these sections is why 47% of mobile feature reworks involve edge cases related to connectivity or permissions (internal data, 2026). This template covers all three.

"The biggest source of mobile re-rework I've seen is a PRD that treats iOS and Android as one platform. They're not. Notification permission flows, background refresh, and share sheet behavior are all different. Specify which platform, or you get a surprise in QA."
— Sam R., Mobile Engineering Lead at a consumer SaaS company

Mobile-specific PRD sections to add

Platform scope: Explicitly state which platforms this feature ships on (iOS / Android / both) and whether parity is required or if platform-specific variations are acceptable. "Spec for iOS first, Android to follow in Sprint+1" is a valid scope decision, just document it.

Offline behavior: For every user action in your user stories, specify: what happens when the user is offline? Does the action fail with an error? Queue for background sync? Disable the UI element? This is the most commonly missing mobile PRD section.

OS permission flows: If the feature requires notifications, camera, location, contacts, or any other OS-level permission: specify the trigger condition (when to request permission), the first-request copy, the denied state behavior, and the re-request flow (settings link).

Performance targets: Mobile has different performance standards than web. Specify: screen load time (target: under 1 second for cached content), animation frame rate (60fps), background refresh interval if applicable.

Mobile edge cases that PRDs commonly miss

Edge case	Example	What the spec must cover
No connectivity	User submits form offline	Queue locally, sync on reconnect, show queue indicator
Interrupted upload/download	App backgrounded mid-upload	Resume from last checkpoint or restart with user confirmation
Permission denied	User denies notification permission	Graceful fallback, settings deep-link, no repeated prompts
Low storage	User cache is full	Error with actionable message, no silent failure
OS upgrade breaking change	iOS 19 changes push token behavior	Note in dependencies, add as tech risk

iOS vs. Android parity decisions to make explicitly

The features that most commonly differ by platform: share sheet (platform-native vs. custom), widget support (different APIs), notification grouping, biometric auth (Face ID vs. fingerprint), and background app refresh policies. Make an explicit decision on each ("platform native" or "custom implementation") in the PRD.

Frequently asked questions

What's different about writing a PRD for a mobile app?

Mobile PRDs need three additional sections that web PRDs don't: (1) offline behavior, what happens to every user action when there's no connectivity; (2) OS permission flows, when and how the app requests notifications, location, camera, etc.; (3) platform specificity, which features ship on iOS, Android, or both, and where platform differences are acceptable. Missing these is the leading cause of mobile feature rework.

How do you handle iOS vs. Android differences in a PRD?

Make an explicit platform scope decision: 'iOS first, Android parity in Sprint+1' or 'platform-native UI elements on both' are both valid, just document them. For features where behavior differs (notification grouping, share sheets, background refresh), specify each platform's expected behavior separately. Don't assume parity unless you've checked the platform APIs.

How do you specify offline behavior in a mobile PRD?

For every user action in your user stories, add a corresponding offline edge case: 'If user is offline when submitting, queue the request locally, show a pending indicator, and sync automatically when connectivity is restored. If sync fails, show an error with a manual retry option.' The patterns are: queue and sync, graceful failure, or disable the feature, make the decision explicit for each action.

What performance targets should be in a mobile PRD?

Standard mobile performance targets: initial screen load under 1 second for cached content, 2 seconds for fresh network content; animations at 60fps; image load under 500ms on 4G; push notification delivery confirmation within 30 seconds. Specify which targets are requirements (blockers for ship) versus goals (aspirational but not blocking).

Do I need a separate PRD for iOS and Android?

No, one PRD with an explicit platform scope section. Document shared requirements once, then call out platform-specific behaviors in the relevant sections (edge cases, acceptance criteria, performance targets). The exception: if the two implementations are substantially different in scope or timing, separate PRDs prevent scope confusion.
