Flutter or React Native — which do you recommend?

We default to Flutter for new projects. It offers the best performance, the most consistent UI across platforms, and Google's active backing. React Native is a strong choice if your team already has deep JavaScript expertise or you need tight web-to-mobile code sharing.

How long does App Store and Play Store approval take?

Apple App Store review typically takes 1–3 business days for new apps. Google Play usually approves within 24–48 hours. We factor this into the launch timeline and prepare all required screenshots, metadata, and privacy policy ahead of submission.

Do you handle App Store submission end to end?

Yes. We set up your developer accounts (or use existing ones), prepare all assets, write optimized descriptions, handle age ratings, and manage the submission process from start to approval.

Can you update or take over an existing mobile app?

Absolutely. We conduct a free technical audit of your existing codebase and give you a clear recommendation — whether that's incremental improvements, a Flutter migration, or a full rewrite.

Do you build the backend too?

Yes. Most mobile projects need a backend — API, push notifications, user auth, database. We build the backend alongside the app, or integrate with your existing systems via REST or GraphQL.

What we build

Mobile App Development Capabilities

Cross-Platform Flutter Apps

One codebase. iOS and Android. Flutter gives you native performance without the cost of two separate codebases. Our Flutter engineers ship pixel-perfect apps that pass App Store review the first time.

Native Performance When It Matters

When Flutter is not the right fit — complex animations, device-specific hardware, or strict performance requirements — we build in Swift and Kotlin. The right tool for the job.

App Store Launch & Optimization

We handle App Store and Play Store submissions, screenshots, metadata, and ASO. Then we stay on to analyze reviews, crash reports, and retention metrics after go-live.

Mobile Backend & API Integration
