Mobile app prompt for an Expo starter

Start a genuine iOS and Android app with Expo, focused screens, device-aware interactions, and a realistic test plan.

When to use it: Use this prompt when the product must run as a native mobile app on iOS and Android. For a responsive website or browser-only prototype, choose a web app prompt instead.

Build an Expo and React Native mobile app for [APP IDEA]. The primary user is [PRIMARY USER], and the one task they must complete in the first release is [CORE TASK]. Target both iOS and Android.

Before coding, propose the smallest useful navigation model and data model. Explain what can work with local sample data and what needs a backend. Then implement:
1. A home screen that makes [CORE TASK] obvious and shows useful current state.
2. A create or edit screen with input validation, keyboard-safe layout, and clear save/cancel behavior.
3. A detail or history screen that lets the user inspect and correct what they entered.
4. Loading, empty, error, offline, and permission-denied states where the flow requires them.

Technical requirements:
- Use an Expo project with current supported setup and idiomatic React Native components. State the commands to install and run it.
- Use accessible labels, readable type, platform-appropriate touch targets, safe areas, and a screen-reader-friendly focus order.
- Persist [DATA TYPE] locally for the prototype. If cloud sync is requested, describe the authentication, data ownership, conflict, and offline-sync plan before adding it.
- Ask for native permissions only at the moment a feature needs them. If [DEVICE FEATURE] is not required, do not request its permission.
- Do not show fake push notifications, app-store readiness, or backend synchronization as completed features.
- Keep secrets outside the app bundle and explain the server-side boundary for privileged operations.

End with a real-device test checklist for both platforms: first launch, interrupted entry, offline save, app restart, larger text, screen reader, and permission denial. List any native build or store-review steps still required.

How to use this prompt

Customize the brief before generating

01
Replace every variable
Use your real project details for app idea, primary user, core task and the remaining placeholders.
02
Remove unnecessary scope
Delete pages, states, integrations, or visual requirements that do not support the first useful version.
03
Add hard constraints
Specify the framework, existing design system, content, data source, accessibility target, and anything the agent must preserve.
04
Test the outcome
Judge the result against this target: A runnable Expo starter with a complete primary flow and honest notes about native permissions, offline data, and build requirements.

Expected outcome

A runnable Expo starter with a complete primary flow and honest notes about native permissions, offline data, and build requirements.

Why it works

Names the native framework and platforms, avoiding an accidental responsive-web result.
Keeps the first release centered on one repeatable user task.
Makes real-device, offline, and permission checks visible before launch claims.

Before you ship

Acceptance checks for this build

The app launches on both an iOS and an Android test device or simulator.
The primary task survives app restart and shows a useful error if saving fails.
The flow remains usable with large text, screen reader, and keyboard visible.
No unsupported notification, cloud-sync, or store-publishing claim appears.
