How much does it cost to build a web or mobile app?

Most projects fall into three bands: a focused MVP from around $15,000, a full production app across web and mobile in the $30,000-$80,000 range, and enterprise platforms quoted custom. Final pricing is fixed-scope and confirmed after a free scoping call, so there are no open-ended hourly surprises.

How long does web or mobile app development take?

A web MVP ships in 6-8 weeks, a single-platform mobile app in 8-10 weeks, a cross-platform iOS and Android app in 10-12 weeks, and a larger enterprise platform in 12-16 weeks. We work in weekly sprints, so you see working software every week, not just at the end.

Do you build native or cross-platform mobile apps?

Both. We build native iOS (Swift) and Android (Kotlin) when you need maximum performance or deep platform features, and cross-platform apps with React Native or Flutter when you want one codebase across both stores at 70-85% shared code. We recommend the right approach for your budget and roadmap during scoping.

What technologies do you use for development?

For mobile: React Native and Flutter for cross-platform, Swift for iOS, Kotlin for Android. For web: React, TypeScript, and Next.js on the frontend; Node.js and Python on the backend. For infrastructure: AWS, Azure, and GCP with containerized deployments, CI/CD pipelines, and performance budgets (LCP under 2.5s).

Do you handle app store submission and post-launch support?

Yes. We manage Apple App Store and Google Play submissions, and every build includes a 90-day post-launch support window covering bug fixes, monitoring, and updates. Ongoing maintenance and feature retainers are available afterward for teams that want a long-term delivery partner.

Who owns the source code and IP?

You do. You receive the full source code, infrastructure-as-code, and complete intellectual property ownership of everything we build. There is no lock-in to proprietary platforms — your team can take over or extend the codebase at any time.
