FAQs

Frequently Asked Questions

Should I build a native app or a cross-platform app?

It depends on your budget, timeline, and app complexity. Native apps (Kotlin for Android, Swift for iOS) offer the best performance and access to device features, but cost more to build and maintain separately. Cross-platform apps (React Native or Flutter) share a single codebase across both platforms — faster to build, more cost-effective, and suitable for the majority of business apps. We'll give you an honest recommendation based on your specific requirements — not what's easier for us to build.

Can you connect the app to my existing website or backend?

Yes. If you already have a WordPress, Shopify, ASP.NET, or MERN/MEAN-based backend, we can build a mobile app that connects to your existing data and logic via APIs — so you're not starting from scratch and your data stays in one place.

How long does it take to build a mobile app?

A simple app with 5–8 screens typically takes 6–10 weeks. A mid-complexity app with custom features, payment integration, and user accounts takes 12–20 weeks. Enterprise or marketplace apps are scoped individually. We'll provide a detailed timeline after the discovery call.

Do you handle App Store and Google Play submission?

Yes — we handle the full submission process for both the Apple App Store and Google Play Store, including store listing setup, screenshots, descriptions, and compliance with platform guidelines. We'll guide you through setting up your developer accounts if you don't already have them.

What happens after the app is launched?

Apps need ongoing care — OS updates, new device compatibility, bug fixes, and feature additions. We offer post-launch support plans so your app stays functional, secure, and up to date without you having to find a new developer every time something needs changing.
