A mobile and web app development company designs, builds, and ships production apps for iOS, Android, and the web. Agility builds custom apps on React, React Native, Flutter, and Node.js, from MVPs to enterprise platforms, delivering in 8 to 14 weeks with app-store launch and full source-code ownership. See our [delivery-platform case study](https://agilitytech.ai/case-studies/payment-automation) for a real build. What we build ## What types of web and mobile applications does Agility build? Agility builds six categories of digital product. **Customer-facing web apps:** React and Next.js SPA and SSR applications with sub-2-second load times and full SEO compatibility. **Native and cross-platform mobile:** React Native and Flutter apps for iOS and Android, sharing 70 to 85% of the codebase. **Internal tooling:** admin dashboards, workflow automation UIs, and data visualisation platforms on enterprise design systems. **E-commerce and marketplaces:** headless commerce on Shopify, Medusa, or custom-built with Stripe and payment gateway integrations. **API and backend services:** Node.js and Python FastAPI backends, PostgreSQL and MongoDB data layers, Redis caching, and cloud deployment on AWS or Azure. **AI-integrated applications:** LLM-powered features, RAG search, and real-time inference endpoints embedded into web and mobile products. Typical delivery: 8 to 14 weeks from scoping to production launch.

[Ask us something else](https://agilitytech.ai/contact) **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 to $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 to 8 weeks, a single-platform mobile app in 8 to 10 weeks, a cross-platform iOS and Android app in 10 to 12 weeks, and a larger enterprise platform in 12 to 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 to 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. ## Ready to build your app? Tell us what you want to build.
