Mobile app development company

We build for iOS, Android, and cross-platform using Flutter and React Native. Flutter is our default recommendation for new projects because it produces a single codebase that compiles to native code on both platforms, delivering near-native performance with roughly 40% less development time compared to building two separate native apps. We use React Native for projects where the team has strong JavaScript expertise and needs tight integration with existing web codebases. Native Swift (iOS) and Kotlin (Android) are reserved for apps with extreme performance requirements — such as real-time video processing or hardware integrations — where cross-platform overhead is not acceptable.

A focused MVP with 4–6 screens, user authentication, and a REST API backend typically takes 10–14 weeks from kickoff to App Store submission. A mid-complexity app (offline support, push notifications, payments, real-time features) runs 16–24 weeks. Enterprise apps with complex data sync, custom device integrations, or regulated industry requirements (healthcare, fintech) take 6–12 months. One of our clients launched a health and wellness app with user check-ins, streak tracking, and social features in 12 weeks. The largest time variable is scope creep — we use weekly sprint reviews to catch scope changes early and reset timelines transparently.

We manage the full submission process as part of every mobile engagement: provisioning profiles and signing certificates for iOS, keystore management for Android, app metadata (screenshots, descriptions, privacy policy URL), review guideline compliance checks, and resubmission if an app is initially rejected. Apple's review process typically takes 1–3 days; Google Play takes 1–7 days for initial review. We build submission into the project timeline so it doesn't come as a surprise at the end. For clients maintaining apps post-launch, we provide a handover package that includes all signing credentials, a documented release process, and recommendations for CI/CD automation via Fastlane.

Cross-platform means you ship one codebase that runs on both iOS and Android, maintained by a single team instead of two. With Flutter specifically, roughly 95% of your code is shared — the platform-specific 5% handles things like native push notification handling or camera permissions. For most B2B and consumer apps, the user experience is indistinguishable from a native app. The practical business benefit: you spend roughly half the budget to reach both platforms simultaneously, and every bug fix or feature update ships to both stores at once. The tradeoff: apps that need cutting-edge iOS-only APIs (like Live Activities or Vision Pro features) may hit limitations that require a native implementation.

Performance starts at architecture: we design data-fetching strategies to minimize round trips, use lazy loading for heavy lists, and profile rendering performance before each release. For offline support, we use SQLite (via Drift for Flutter) or WatermelonDB (for React Native) as local databases, with a sync engine that resolves conflicts when connectivity is restored. One of our clients needed their field service app to work in areas with no cell service — we built an offline-first architecture where technicians could complete and submit work orders without connectivity, with automatic sync when they returned to range. We test offline scenarios explicitly in our QA process for every release.
