Your users spend 4+ hours a day on their phones — 88% of that time is inside apps. A great mobile app is not just a smaller version of your website. It is a faster, more personal, more engaging experience that lives in your customer's pocket 24/7. We build apps that use device capabilities — camera, GPS, biometrics, push notifications, offline storage, NFC, AR — to create experiences the web simply cannot match. Here is what we build.
Native iOS Apps (Swift & SwiftUI)
We build native iOS apps with Swift and SwiftUI that feel like they belong on the iPhone and iPad. Fluid 60fps animations, Apple's Human Interface Guidelines, Face ID and Touch ID authentication, Apple Pay integration, HealthKit for fitness apps, Core Data and SwiftData for offline storage, CloudKit for sync, push notifications with APNs, Siri Shortcuts, App Clips, widgets, and deep linking. We handle the entire process — Xcode development, unit and UI testing with XCTest, performance profiling with Instruments, TestFlight beta distribution, and App Store submission with proper metadata, screenshots, and App Store Optimization (ASO). Your iOS app is fast, elegant, and ready for 1.5 billion Apple devices worldwide.
Native Android Apps (Kotlin & Jetpack)
We build native Android apps with Kotlin and Jetpack Compose that run beautifully across 3+ billion Android devices. Material Design 3 for modern, consistent UI. Jetpack libraries — Navigation, Room database, WorkManager for background tasks, DataStore for preferences, CameraX for camera features, and Hilt for dependency injection. Google Pay, Firebase Cloud Messaging for push notifications, Google Maps SDK, ML Kit for on-device AI, biometric authentication, and offline-first architecture with Room + sync. We test across real devices and emulators, optimize for different screen sizes (phones, tablets, foldables), and handle Google Play Store submission with staged rollouts, A/B testing, and crash monitoring with Firebase Crashlytics.
Cross-Platform Apps (React Native)
One codebase, two platforms, 90%+ code sharing. React Native lets you build iOS and Android apps simultaneously using JavaScript and React — cutting development time and cost nearly in half. Used by Instagram, Facebook, Shopify, Discord, Pinterest, and Bloomberg. We build with Expo for rapid development, React Navigation for smooth screen transitions, Redux Toolkit or Zustand for state management, React Native Reanimated for 60fps animations, and native modules when you need platform-specific power. Camera, GPS, push notifications, in-app purchases, offline storage with WatermelonDB, and real-time features with WebSockets. One team, one codebase, both app stores — and your users cannot tell the difference from native.
Cross-Platform Apps (Flutter & Dart)
Flutter compiles to truly native ARM code — no JavaScript bridge, no performance compromise. One Dart codebase produces pixel-perfect apps for iOS, Android, web, and desktop. Used by Google, BMW, Toyota, eBay, Alibaba, and Nubank (100M+ users). We build with Flutter's widget system for custom, brand-unique UI, Riverpod or BLoC for state management, Go Router for navigation, Drift for local databases, Dio for networking, Firebase for auth and push notifications, and platform channels for native API access. Smooth 120fps animations, custom painters for complex graphics, and fast iteration with Hot Reload. When your app needs to look identical on both platforms with premium performance — Flutter is the answer.
Mobile UI/UX Design & Prototyping
Great apps start with great design. We design mobile experiences that are intuitive, beautiful, and conversion-optimized. User research and persona mapping, competitive analysis, wireframes and information architecture, high-fidelity UI design in Figma, interactive prototypes for usability testing, and micro-interaction design that makes your app feel alive. We follow Apple's Human Interface Guidelines and Google's Material Design 3. Accessibility (WCAG), dark mode support, responsive layouts for all screen sizes (including tablets and foldables), and design systems with reusable components so your app stays consistent as it grows. We test designs with real users before a single line of code is written — saving you months of rework.
App Store Launch & Growth
Building the app is only half the battle — launching and growing it is the other half. We handle end-to-end app store deployment: App Store Connect and Google Play Console setup, screenshot and preview video creation, keyword-optimized descriptions (ASO), proper categorization, privacy policy and data safety declarations, and compliance with Apple and Google review guidelines. Post-launch, we set up analytics (Firebase Analytics, Mixpanel, Amplitude), crash monitoring (Crashlytics, Sentry), A/B testing for onboarding flows, push notification campaigns, in-app review prompts, deep linking for marketing, and staged rollouts. We help you acquire, retain, and engage users — not just build the app and walk away.

Frequently Asked Questions
Got questions about mobile app development? Here are simple, honest answers to what people ask us most.
Native app vs cross-platform — which should I choose?
It depends on your priorities. Native apps (Swift for iOS, Kotlin for Android) give you the best performance, full access to every platform API, and the most polished user experience — but you need two separate codebases and two development teams. Cross-platform (React Native or Flutter) lets you write one codebase for both iOS and Android, saving 30-50% on development costs and time. React Native is perfect if your team knows JavaScript/React. Flutter is ideal when you want pixel-perfect, identical UI on both platforms with top-tier performance. For most startups and mid-sized businesses, cross-platform is the best value. For apps that demand absolute peak performance (gaming, AR, complex animations), native is the way. We help you decide based on your budget, timeline, and technical needs.
How much does it cost to build a mobile app?
A simple app with basic features (5-10 screens, authentication, API integration) typically costs $15,000-$40,000. A medium-complexity app (e-commerce, social features, payments, maps, push notifications) runs $40,000-$100,000. A complex enterprise or marketplace app with advanced features (real-time chat, video calling, AI, AR, multi-role systems) can range from $100,000-$300,000+. Cross-platform development (React Native or Flutter) saves 30-50% compared to building two separate native apps. These ranges include design, development, testing, and deployment — but not ongoing maintenance. We provide a detailed proposal with a fixed-price estimate before starting, so there are no surprises. Every dollar is accounted for.
How long does it take to build and launch a mobile app?
A simple MVP takes 6-10 weeks. A medium-complexity app takes 3-5 months. A feature-rich enterprise app takes 5-9 months. This includes everything — UI/UX design (2-4 weeks), development, backend API integration, testing across devices, and App Store/Google Play submission. App Store review typically takes 1-3 days for iOS and a few hours for Google Play. We work in 2-week sprints and deliver working builds to TestFlight (iOS) and internal testing (Android) so you can see progress and give feedback throughout. We give you a clear timeline before we start and stick to it.
Will my app work offline?
Yes, if you need it. We build offline-first mobile apps that work without an internet connection and sync data automatically when connectivity returns. On iOS, we use Core Data or SwiftData with CloudKit sync. On Android, we use Room database with WorkManager for background sync. In React Native, we use WatermelonDB or AsyncStorage. In Flutter, we use Drift (SQLite) with custom sync logic. This is critical for field service apps, healthcare apps, logistics apps, and any app used in areas with unreliable connectivity. Users see cached data instantly, make changes offline, and everything syncs seamlessly when they are back online — with proper conflict resolution so no data is lost.
Do you handle App Store and Google Play submission?
Yes, end to end. We handle everything needed to get your app approved and published. Apple App Store — developer account setup, App Store Connect configuration, app icon and screenshots in all required resolutions, App Privacy details, content ratings, TestFlight beta testing, and review submission. Google Play Store — Play Console setup, store listing with feature graphics, data safety declarations, content ratings, staged rollouts, and pre-launch reports. We know the guidelines inside and out, so your app passes review the first time. We also set up App Store Optimization (ASO) — keyword research, optimized titles and descriptions, and A/B testing of screenshots to maximize organic downloads.
Do you provide ongoing app maintenance and updates?
Absolutely. Mobile apps require ongoing maintenance — Apple and Google release major OS updates every year, and your app needs to stay compatible. We handle iOS and Android OS compatibility updates, bug fixes, performance optimization, security patches, dependency updates, new feature development, and server-side API maintenance. We monitor crash rates with Firebase Crashlytics or Sentry, track user behavior with analytics (Mixpanel, Amplitude), run A/B tests on new features, optimize app size and load times, and handle app store updates with proper release notes. Think of us as your permanent mobile team — we keep your app running, growing, and earning 5-star reviews.
