Mobile App Development

Both is the default for cross-platform — React Native delivers 90%+ code reuse with platform-respecting UX, and the performance gap to fully-native is small enough to be invisible to users for the vast majority of products. Native Swift or Kotlin becomes the right call when you need deep platform integration (advanced ARKit, complex Bluetooth peripherals, specific gaming engines), when the team has strong existing native expertise, or when one platform genuinely dominates your audience. We give you the recommendation that fits your product — not the one that maximises billable hours.

A focused MVP — core flows, single platform target, no heavy backend — typically takes 6–10 weeks. A full production app with custom backend, multiple integrations, and both iOS and Android typically takes 12–20 weeks. A complete SaaS platform with multi-tenancy and subscription billing typically takes 6–9 months. Timeline depends heavily on scope clarity, integration count, and how ready you are to make product decisions — we are explicit about which factors will move the line during scoping.

Yes, end-to-end. Provisioning profiles, signing certificates, App Store Connect setup, Google Play Console setup, privacy manifests, data safety declarations, ATT disclosures, screenshots, and store listing copy. We also configure over-the-air updates (Expo Updates or CodePush) so future small releases don't require a full store review for every change.

Yes. We build production-grade Node, Next.js, or Python backends with REST or GraphQL APIs, secure authentication, push notification integration, and real-time features where the app needs them — see our app API and backend integration and database and API development services. Where you already have a backend or third-party API to integrate with, we build mobile-side integration around it with proper retry logic, idempotency, and observability.

Where the use case justifies it, yes. Offline-first architecture — local caching, queued mutations, conflict resolution on reconnect, and clear UI for offline states — is built into the app from the start when it matters. For products with mostly-online workflows, we still cache critical content so the app degrades gracefully on slow networks rather than failing entirely.

Authentication via OAuth 2.0 or JWT with proper refresh-token rotation, secure-enclave key storage for sensitive credentials, biometric unlock where the platform supports it (Face ID, Touch ID, Android BiometricPrompt), and OWASP Mobile guidance applied for storage, transit, and code-level security. Payment flows use Stripe SDK or platform-native Apple Pay and Google Pay to keep PCI scope minimal.

Yes — and we strongly recommend it. Mobile apps degrade silently if left alone: dependencies accumulate vulnerabilities, iOS and Android ship breaking changes annually, store policies tighten without notice. Our app maintenance and support retainers cover dependency and security patching, OS compatibility testing on every major release, crash and performance monitoring with engineer triage, store policy compliance updates, and a backlog of small improvements informed by real usage data.

Yes. Whether the existing app is performant but visually dated, structurally sound but missing key features, or fundamentally limited in ways that justify a rebuild, we audit honestly and recommend the path that gives you the best outcome for the budget. Partial rebuilds typically use a strangler-fig approach rather than throwing away what works.

React Native with TypeScript is our default for cross-platform mobile work. Native Swift or Kotlin modules where genuine native access is required. Backends typically Node.js with TypeScript, with PostgreSQL or MongoDB databases. Navigation via React Navigation, state via React Query or Zustand, builds via EAS Build or GitHub Actions, monitoring via Sentry or Firebase Crashlytics. We pick technology by what your application actually needs — not by which framework is fashionable this quarter.
