FAQ
1. Which apps and platforms can you fix?
We fix bugs in Flutter and React Native apps for Android and iOS, including Expo projects. Our mobile app bug fix service covers crashes, UI errors, broken features and performance issues. Share your framework, app version and affected platform so we can check whether the issue fits this gig.
2. What should I send before ordering a mobile app bug fix?
Share error messages, screenshots or video, steps to reproduce the bug, and what should happen instead. Include your app link, framework version and source code availability. We review these before confirming feasibility, scope, price and delivery. Ask us if you need help gathering the details.
3. Can you help if I do not know why my app is failing?
Yes. Describe what goes wrong, when it happens and which devices are affected. We can investigate Flutter or React Native bugs using the code, logs and test steps. If an issue is intermittent or depends on another service, we explain the investigation needed and agree on the scope before work.
4. Can you fix crashes, build errors and bugs after an update?
Yes. We troubleshoot app crashes, blank screens, freezes and app build errors, including Gradle, Xcode, CocoaPods and dependency issues. Flutter, React Native or Expo updates can also be reviewed. Share the code, error log and recent changes so we can assess the cause and scope the repair.
5. Can you fix Firebase, API, login and payment issues?
Yes. We investigate Firebase authentication, database and notification bugs, API integration errors, login failures and broken payment flows. We check the app and backend connections to identify where the problem occurs. Third-party service changes or backend repairs are scoped after review.
6. Which package should I choose, and how long will the fix take?
Basic covers 1 minor UI or logic bug. Standard covers up to 3 related UI, API or Firebase bugs. Premium covers 1 agreed complex crash, build error or performance issue. We review your code to recommend a package and confirm price, delivery and revisions. Larger work is quoted separately.
7. How will you test my app and deliver the fixes?
We test the fixes and affected app flows on agreed Android or iOS devices. You receive updated source code, a clear explanation of the changes and testing details. We also check related existing behavior. If you need a broader app audit, we can agree on that testing scope before you order.
8. Can you work on apps built by another developer or an AI tool?
Yes, after code review. We can fix Flutter and React Native bugs in apps built by another developer or an AI app builder when source code is available. Share the repository or exported project and setup details. A store link, APK or screenshots alone usually cannot support code-level repairs.
9. Is my source code confidential, and can you sign an NDA?
We can review and sign an NDA before you share confidential code or project details. Repository access can be arranged through invitations with permissions for the agreed app bug fix. We can use test accounts and sample data, and confirm handover and access arrangements before starting.
10. What revisions and support are included after the bug fix?
Revisions follow the limits and repair scope in your package or custom offer. Bug-fix support for delivered changes is 20 days to 3 months, depending on project size, and is agreed before ordering. Unrelated bugs, added features, redesigns and mobile app maintenance can be quoted separately.
