Cross-Platform Mobile App Development
Build once, ship everywhere. We develop cross-platform iOS and Android apps with React Native — native performance, offline-first data, push notifications, and full App Store and Play Store deployment.
We build mobile apps with React Native and Expo so a single codebase powers both iOS and Android — faster to build, cheaper to maintain, and consistent across devices. Where native performance matters, we drop down to native code.
Our mobile apps are designed offline-first, with reliable sync, push notifications, deep linking, and in-app purchases where needed. If you already have a Next.js web app, we can share logic and design between web and mobile.
From consumer apps to internal enterprise tools, we handle the whole journey: design, development, testing on real devices, and publishing to the App Store and Google Play.

Mobile Apps — Questions Answered
Common questions clients ask before hiring us for mobile apps.
Should I build a native or cross-platform app?
For most products, React Native cross-platform is the best balance of cost and quality — one codebase for iOS and Android with near-native performance. We recommend fully native only when heavy platform-specific features are needed.
Do you publish the app to the stores?
Yes. We handle App Store and Google Play submission, including screenshots, metadata, and the review process, and can manage updates after launch.
Can my mobile app share code with my web app?
Yes. If your web app is built with React/Next.js, we can share business logic, types, and design tokens, which speeds up development and keeps behaviour consistent.
How long does it take to build a mobile app?
A focused MVP app typically takes 4–8 weeks depending on features. We deliver in sprints with builds you can test on your own device throughout.
How much does a mobile app cost?
Cross-platform MVP apps generally start around $1,500 and scale with complexity. We provide a fixed quote after a free scoping call.
Do you maintain apps after release?
Yes. We offer ongoing maintenance covering OS updates, dependency upgrades, bug fixes, and new features so your app stays compatible and reliable.
