FAQ
Can you fix bugs in any mobile app?
Yes. We fix bugs in Flutter, React Native, Swift, Kotlin and web apps built with React or Node.js. Share your codebase and describe the issue — we review it and confirm we can fix it before you order.
How do you charge for bug fixing?
Basic covers up to 3 bugs. Standard covers up to 10 bugs or one complex issue. Premium covers unlimited bugs within 30 days. For large or unknown scope message us first for a custom offer.
What if you can't fix the bug?
We assess before committing. If we review your code and determine we cannot fix a specific issue we will tell you honestly before you pay — not after. We never take an order we cannot complete.
