Frequently Asked Questions

React Native vs Flutter — which should I choose?+
React Native is ideal if your team already knows JavaScript/TypeScript or you need deep integration with web codebases. Flutter has a more performant rendering engine and is excellent for pixel-perfect custom UIs. We help you choose based on your specific needs.
How long does a mobile app take to build?+
A focused MVP with 3–5 core screens typically takes 8–10 weeks. A fully featured consumer or enterprise app with backend integration is usually 14–20 weeks.
Do you handle App Store and Play Store submission?+
Yes. We manage the complete submission process including provisioning profiles, certificates, store listings, screenshots, privacy policies, and review issue resolution.
Can you add a mobile app to an existing web product?+
Absolutely. If your web product has a REST or GraphQL API, we can build a mobile app that shares the same backend. We also help extract shared business logic into a common package.
How do you test mobile apps?+
We use Detox and Maestro for E2E testing, Jest for unit tests, and TestFlight/Firebase App Distribution for beta testing. We also test on a range of physical devices across OS versions.
What happens after the app is live?+
We offer post-launch retainers covering crash monitoring (Sentry), OTA updates (Expo EAS), OS version compatibility, and feature iteration sprints.
