Mobile apps your users keep coming back to

Native iOS, Android, and cross-platform apps. We handle the build, the backend, the App Store submission, and what happens after launch.

Platforms

iOS, Android, and cross-platform

We work with all three. If you are not sure which fits your project, we will tell you honestly after a 30-minute call.

01

Native iOS

Swift and SwiftUI, following Apple's Human Interface Guidelines. Full platform integration: ARKit, CoreML, HealthKit. App Store submission handled by us.

  • Swift, SwiftUI, UIKit, and the full iOS SDK - modern declarative UI with UIKit interop where legacy code requires it
  • ARKit, CoreML, HealthKit, MapKit integrations - platform APIs used correctly, not just bolted on
  • iPad and Apple Watch extensions - when the product scope includes the full Apple device ecosystem
  • App Store submission and ASO - metadata, screenshots, review guidelines — we handle the submission
02

Native Android

Kotlin and Jetpack Compose, Material Design 3, deep Google services integration. We test across device profiles and handle the Play Store submission.

  • Kotlin, Jetpack Compose, and the full Android SDK - declarative UI, no XML layout files, modern architecture patterns
  • Material Design 3 and custom design systems - follows the spec where it fits, extends it where the brand requires
  • Firebase, Google Maps, Play Billing integration - platform services connected correctly with proper error handling
  • Play Store submission and device matrix testing - tested on real devices across screen sizes, not just emulators
03

Cross-platform: Flutter and React Native

One codebase for iOS and Android. Good for MVPs, content apps, and products where launch speed matters. Migration to native is straightforward if you outgrow it.

  • Flutter for pixel-perfect UI and complex animations - renders its own widgets, looks identical on every device
  • React Native for shared code with web frontend - TypeScript, large ecosystem, JSI for near-native performance
  • 70–90% shared codebase between platforms - platform-specific modules added only where native API is required
  • Hot reload for rapid iteration - design feedback visible within seconds during development cycles

Full service

Beyond the app itself

A mobile app is more than screens. Here's what else goes into it.

Backend & APIs

Node.js, Python, REST, GraphQL, WebSockets. Real-time sync, push notifications (APNs, FCM), file storage, auth (OAuth2, biometric, SSO).

UI/UX design

User research, wireframes, interactive prototypes in Figma. Platform-native design following Apple HIG and Material Design 3.

DevOps & CI/CD

Automated builds (Fastlane, Bitrise, GitHub Actions), automated testing, beta distribution (TestFlight, Firebase App Distribution).

Analytics & growth

Firebase Analytics, Amplitude, Mixpanel. A/B testing, feature flags, crash reporting (Sentry, Crashlytics), App Store Optimization.

Technology

Mobile tech stack

iOS

Swift, SwiftUI, UIKit, Combine, Core Data, ARKit, CoreML, WidgetKit, App Clips, StoreKit 2

Android

Kotlin, Jetpack Compose, Room, Hilt, WorkManager, CameraX, ML Kit, Google Billing Library

Cross-platform

Flutter, Dart, React Native, TypeScript, Expo, Riverpod, Bloc, Redux Toolkit

Backend & cloud

Node.js, Python, Firebase, Supabase, AWS (Amplify, Lambda, S3), Google Cloud, REST, GraphQL, WebSockets

Our process

From idea to App Store

Clear path, no surprises. Progress visible at every step.

1. Discovery

Audience, features, platform strategy, features, platform strategy, and technical architecture. 1–2 weeks.

2. UI/UX design

Wireframes and interactive prototypes in Figma. User testing before development starts. 2–3 weeks.

3. MVP

Core features built and deployed to TestFlight/internal testing. Real user feedback early. 6–10 weeks.

4. Full build

All features, integrations, polished UI, automated tests. Working demos every 1–2 weeks. 2–4 months.

5. Launch

App Store and Google Play submission, metadata, screenshots, compliance. We handle the review process.

6. Grow & iterate

Analytics, A/B tests, crash monitoring, feature releases, ASO. We stay for as long as you need us.

Why Oberig

Why build your app with us

Full product, more than an app

Backend, admin panel, API, infrastructure. all part of the same project. One team, no vendor coordination.

Platform expertise

iOS engineers who dream in SwiftUI. Android engineers who live in Compose. "Native quality" isn't marketing speak here.

Ship to store, not just staging

App Store and Google Play submission, review handling, ASO, post-launch monitoring. Your app goes live for real users, not to a staging URL.

20+ years of software

Mobile is part of a bigger engineering practice. Complex integrations? Legacy backends? Enterprise security? Solved it. Multiple times.

FAQ

Mobile development questions

Should I build a native or cross-platform app?

Native (Swift/Kotlin) gives the best performance and platform-specific UX. ideal for performance-critical apps, AR, games, and deep platform integrations. Cross-platform (Flutter/React Native) is faster and more budget-friendly, with one codebase for both iOS and Android. ideal for MVPs, content apps, and simultaneous launches. We'll help you decide based on your goals, timeline, and budget.

How long does it take to build a mobile app?

A simple MVP takes 8–12 weeks A mid-complexity app with backend, auth, and payments takes 3–5 months A complex enterprise app may take 6–9 months Agile sprints mean you see working builds every 1–2 weeks, not at the end.

How much does mobile app development cost?

An MVP starts from €20,000–40,000 A production app with backend typically costs €50,000–120,000 Enterprise apps range from €100,000 to €250,000+ Cross-platform is typically 30–40% cheaper than building two separate native apps. Detailed estimate after a free discovery call.

Do you handle App Store and Google Play submission?

Yes, full-cycle. Metadata, screenshots, privacy declarations, compliance docs. Submitted to both stores, review process managed, rejections handled. Phased rollouts and staged releases included.

Do you build the backend too?

Yes. It is one of our strengths. The complete stack: mobile app, backend API, admin panel, cloud, CI/CD. One team builds and owns it all. No separate backend vendor to chase.

Can you add AI features to my mobile app?

Yes. On-device ML is available (CoreML, TensorFlow Lite) for fast offline inference, and cloud AI (OpenAI, custom models) for more complex tasks. Think chatbots, image recognition, personalized recommendations, voice commands, smart search.

What about app maintenance after launch?

Ongoing support: bug fixes, OS compatibility, performance monitoring, crash reporting (Sentry, Crashlytics), new features, ASO. Most clients stick around. The app keeps getting better.

Can you redesign an existing mobile app?

Yes. We regularly take over existing apps. audit the codebase, identify UX problems, and either incrementally improve or rebuild with modern architecture We preserve your user base, data, and store listings during the transition.

What should your app do?

iOS, Android, or both — describe the core use case and we'll suggest the right approach.
