FAQ
Common questions
Should I build native or cross-platform?
For consumer apps with complex animations and hardware integrations, native (Swift/Kotlin) gives the best experience. For business apps or tighter budgets, React Native or Flutter deliver a near-native experience from one codebase.
How long does it take to get an app on the App Store?
Development takes 8–16 weeks depending on features. Store review typically adds a few days. We manage the submission end-to-end, including screenshots and metadata.
What is your maintenance process after launch?
We monitor crash reports and performance, ship fixes for critical bugs promptly, and test each new iOS and Android release proactively.
Can you add features to an app someone else built?
Yes. We begin with a codebase audit covering architecture, test coverage and technical debt, then provide a realistic plan for new features or modernisation.
Do you build the backend API as well?
Yes. Most of our mobile projects include a backend built with Node.js or Python, a REST or GraphQL API, a PostgreSQL database and cloud hosting — delivered as one integrated project.
