Perguntas frequentes
Can you work with my existing app code?
Yes. We work with any existing codebase — Flutter, React Native, Swift, Kotlin, React, Node.js. We review your code first, identify issues, and give you an honest assessment before recommending a fix or rebuild.
How do you decide whether to fix or rebuild?
We assess your existing code quality, architecture and technical debt. If fixing is faster and cheaper we fix. If the codebase is too broken we recommend a rebuild. We always give you an honest recommendation, not the most expensive one.
Can you add new features to my existing app?
Yes. Adding features to existing mobile or web apps is one of our most common requests. We review your current architecture first to ensure new features integrate cleanly without breaking existing functionality.
