Mobile apps for iOS & Android at 60fps
Native Swift and Kotlin where the platform demands it, React Native or Flutter where shared code and speed matter more — profiled for a smooth 60fps on a mid-range Android as well as the latest iPhone.

Mobile development services
Native Swift and SwiftUI apps built for the App Store, not a cross-platform compromise.
Native Kotlin and Jetpack Compose for the Play Store, tuned for mid-range devices too.
Cross-platform apps with 90%+ shared code, without giving up native feel.
Dart-powered apps for iOS, Android, and web from a single, fast-iterating codebase.
Progressive web apps that install like native, when a store submission isn't the goal.
OS updates, bug fixes, and feature additions so a shipped app doesn't quietly rot.
// technical depth — mobile capabilities
Built for real-world conditions
Profiled with Instruments and Systrace — no dropped frames, on flagship or mid-range hardware.
SQLite, Room, and MMKV with background sync queues that hold up on real-world connections.
APNS and FCM, rich notifications, and deep links that route users straight into the app.
StoreKit 2, Play Billing, and subscription management wired up and store-compliant.
Biometrics, Keychain, Keystore, and certificate pinning standard on every build.
MapKit, Google Maps, geofencing, and background location handled without draining the battery.

Mobile development process
Platform-native Figma designs and clickable TestFlight builds — so you're testing the feel of the app, not a static mockup.
- ✓Platform-native Figma designs
- ✓Clickable TestFlight build
- ✓Scope locked before sprint one
Feature sprints with daily builds on physical devices — not just a simulator — so performance issues surface early.
- ✓Daily builds on physical devices
- ✓Feature sprints with clear scope
- ✓Offline-first from the first build
A 20+ device matrix via Firebase Test Lab, profiled with Instruments and Systrace to kill dropped frames before launch.
- ✓20+ device matrix, Firebase Test Lab
- ✓Instruments / Systrace profiling
- ✓Zero dropped-frame regressions
End-to-end App Store and Play Store submission management, so policy rejections don't blindside your launch date.
- ✓App Review & Play Policy compliance
- ✓Store listing & assets prepared
- ✓Submission managed end to end

Native depth or cross-platform reach — decided by the work
We handle App Review and Play Policy compliance to avoid rejections.
60fps profiled — no jank in any of our apps, on flagship or mid-range hardware.
Designed for real-world connectivity, not ideal lab Wi-Fi conditions.
Biometrics, certificate pinning, and secure storage standard on every build.
Choosing a mobile app development company is really a bet on two things: whether the app runs at a smooth 60fps on a mid-range Android as well as the latest iPhone, and whether it clears App Review and Play policy without weeks of back-and-forth. We reach for SwiftUI and Jetpack Compose when you need deep hardware access — BLE, background location, StoreKit 2 subscriptions — and React Native when 90% shared code and faster iteration outweigh native gains. Either way, the app is offline-first from day one, with SQLite or MMKV and background sync queues. Most apps also need a backend, and we build that in the same team — a scalable SaaS platform with the APIs and webhooks your app talks to, rather than handing you a client that points at nothing. If you have an existing app in trouble, we audit the codebase first and tell you honestly whether to modernise or rewrite.
// mobile-app-development.faq.md
Native for maximum performance and platform-specific features. React Native or Flutter when cost-efficiency and code sharing outweigh native advantages.
Simple app: 6–10 weeks. Complex app with backend: 3–5 months. We scope in week one.
Yes — we offer retainer plans for OS updates, bug fixes, and feature iterations.
Yes — we do code audits, then either modernise or rewrite depending on the state of the codebase.
