# How to Use Cursor for Mobile App Development

> Cursor can speed up React Native development, but the biggest gains come from repository context, small diffs and clear engineering constraints rather than giant prompts.

Cursor and similar AI code editors are most useful when they can reason about an existing repository, not just generate isolated snippets.

For Expo and React Native projects, the goal is to make the AI understand the same conventions a new engineer would need to learn.

## Start by making the repository predictable

Keep naming and directory structure consistent. A project might separate route files, reusable UI and domain logic:

```text
app/
components/
features/
lib/
hooks/
types/
```

When one feature uses three different patterns for data fetching, the AI has no reliable example to follow.

## Ask the editor to inspect before editing

A strong request starts with discovery:

```text
Inspect the current subscription flow and identify the files responsible for
paywall display, purchase state and entitlement checks. Do not make changes yet.
```

After the model maps the feature, ask for the smallest implementation plan. This is usually safer than one prompt that combines analysis and a large code rewrite.

## Use explicit constraints

Useful constraints include:

```text
- preserve Expo Router navigation
- use existing design tokens
- no new dependency unless necessary
- no `any` types unless justified
- do not change unrelated files
- keep secrets out of client code
- run typecheck after implementation
```

These rules reduce the most common AI-editor failure mode: solving a local problem by adding global complexity.

## Use Cursor for repetitive changes

AI editors are excellent at work such as:

- adding loading and error states across similar screens,
- converting repeated UI into a reusable component,
- migrating a set of TypeScript interfaces,
- adding localization keys,
- writing tests around an existing pure function,
- tracing where a value is used.

They are less trustworthy when the task requires an unstated product decision.

## Debug with evidence

Do not prompt with only "it doesn't work." Give the model the error, reproduction steps, expected behavior and relevant logs.

For a mobile bug, a good report might include:

```text
1. Fresh install
2. Sign in
3. Open paywall
4. Complete purchase
5. Modal closes but entitlement remains false until restart
```

That turns debugging into a state-transition problem rather than a guessing exercise.

## Review generated diffs

Before accepting a broad change, look for:

- duplicated utilities,
- new dependencies,
- deleted error handling,
- environment variables exposed to the client,
- silent changes to navigation or data models,
- hard-coded values that should be configuration.

AI can write code quickly enough to create technical debt quickly too.

## Keep release operations outside the prompt fantasy

An editor can prepare EAS configuration and store metadata, but publishing still depends on real Apple and Google accounts, certificates, package identifiers, review requirements and product decisions.

Treat shipping and monetization as operational systems, not just code generation tasks.

## The best Cursor workflow

The most reliable pattern is:

**inspect → plan → make a small change → test → review the diff → commit**.

That loop keeps speed high without giving the model unlimited permission to reshape the project.

## Frequently asked questions

### Is Cursor good for React Native?

Yes. Repository-aware editing, TypeScript support and multi-file changes make AI editors useful for React Native and Expo projects.

### Should I let Cursor refactor the whole app at once?

Usually no. Smaller scoped refactors are easier to review, test and revert.

### What should I include in a Cursor prompt?

Describe the user-visible goal, relevant constraints, existing patterns to reuse, what must not change and how success should be tested.
