Client Satisfaction

Building a mobile app is the single biggest investment most startups make. Choose the wrong development partner and you waste months and tens of thousands of dollars on code that doesn't scale, crashes in production, and needs a complete rewrite at Series A.

We've built 15+ production apps that are live on the Play Store and App Store right now. Our Flutter expertise means you get native performance on both platforms from a single codebase — no maintaining two separate apps, no doubling your development budget.

Every app we build uses clean architecture, proper state management, automated testing, and CI/CD pipelines. Your future CTO won't need to throw it away. We deliver code that grows with your startup — from first beta testers to your first million users.

FAQ

Frequently Asked Questions

How much does it cost to build a startup app?

A basic MVP starts at $3,000–5,000. Full-featured apps with backend, payments, and admin panels range from $6,000–18,000 depending on complexity.

Why Flutter over React Native?

Flutter compiles to native ARM code (better performance), has a richer widget system, and Google's investment continues to grow. For most startups, Flutter is the faster, more cost-effective choice.

How long does it take to build a startup app?

An MVP takes 6–8 weeks. A full-featured app takes 12–16 weeks. We move fast by using proven architecture patterns and reusable components.

Do you publish to both Play Store and App Store?

Yes. We handle the entire submission process including app store optimization (ASO), screenshots, descriptions, and compliance for both platforms.

Will I own the code?

Yes, 100%. Full source code ownership transfers to you upon project completion. No vendor lock-in, no license fees.

Can the MVP code scale?

Absolutely. We use production-grade architecture from day one. The same code serves your first 100 users and your first 100,000.

What about app maintenance after launch?

Every project includes 3 months of post-launch support. We also offer ongoing maintenance plans covering updates, bug fixes, and new features.

Do you work with international startups?

Yes. We work with startups globally — US, UK, Europe, Middle East, and Southeast Asia. Time zone overlap and clear communication are priorities.
