Fix My Rork App
That Does Not Work in Production

Expo Go ≠ a real device build

Rork previews run on Expo Go or Rork's own simulator — environments that handle native module complexity automatically. When you move to a real EAS Build or submit to the App Store, those complexities appear immediately. Native module linking failures, Expo SDK version mismatches, and missing privacy manifest files (required by Apple since May 2024) are the most common blockers. Apps that run fine in the Rork preview routinely fail app store review without targeted fixes to the build configuration.

React Native performance on real devices

Rork generates React Native screens quickly, but the generated component architecture often creates unnecessary re-renders, unvirtualised long lists, and image loading patterns that cause janky scrolling on real hardware. Simulators smooth over these issues because they run on fast CPUs with no memory pressure. Fixing this requires hands-on React Native experience — profiling with Flipper or React DevTools Profiler and rewriting the affected components, not just adjusting Rork prompts.

Broken screens and navigation

Screens crash, navigation stacks break, or back behaviour is wrong. React Native stack and tab navigation fixed properly.

Auth not working

Sign-up, login, or token refresh breaks on real devices. Session handling and auth flow fixed end-to-end.

API calls failing

Backend calls return errors or time out in production. Headers, auth tokens, error handling, and retry logic fixed.

Database connection errors

Supabase, Firebase, or other backends not connecting correctly. Environment config and query issues resolved.

Build failures

App does not build for iOS or Android. Native module issues, dependency conflicts, and Expo config problems fixed.

App Store submission blockers

Rejected by Apple or Google for technical reasons. Privacy manifests, permissions, splash screens, and compliance issues fixed.

Performance issues

Slow screens, janky scrolling, or excessive re-renders. Component optimisation and list virtualisation applied.

Security vulnerabilities

API keys exposed in the app bundle, missing input validation, or insecure storage. Rork-generated code audited and hardened.

01

Share your Rork project

Grant access to the Rork project or share the exported code. Describe what is broken or not working as expected.

02

Get a flat-rate quote

I identify the issues and send a fixed price. You approve before I start — no surprises.

03

I fix the code

All fixes made directly on Rork or in the exported codebase — whichever suits your setup.

04

Test and ship

Your fixed app is ready to test on device and submit to the App Store or Play Store.

What kinds of Rork issues do you fix?

Broken screens, navigation errors, API call failures, backend connection issues, auth problems, broken builds, app store submission blockers, and any behaviour that does not match what Rork generated in the preview.

Can you work directly inside Rork?

Yes. Share access to your Rork project and I fix the issues directly on the platform. You can also export the code if you prefer to work from a repo.

How quickly can you fix it?

Most fixes within 24–48 hours. I give you a clear timeline before starting — no optimistic guesses.

How does pricing work?

I review the project, identify what is broken, and send a flat-rate quote per issue. You approve before any work starts.

I do not understand React Native — can you still help?

Yes. Rork generates React Native code under the hood. You do not need to understand it. Describe what is broken and I will handle the rest.

Can you also add features to my Rork app?

Yes. Beyond bug fixes I can add screens, integrate third-party APIs, implement proper auth, or prepare the app for a real App Store or Play Store submission.
