App types

Which app type
is right for you?

Native iOS, native Android, cross-platform or PWA: every project has different priorities. The choice depends on required performance, hardware access, budget, time to market and store presence.

Swift · Apple HIG · App Store

Native iOS

iOS app development in Swift + SwiftUI. Maximum performance, full API access (Apple Pay, ARKit, HealthKit, CoreML), Apple Human Interface Guidelines, App Store publishing.

What's included

Kotlin · Material 3 · Play Store

Native Android

Android app development in Kotlin + Jetpack Compose. Material Design 3, access to all Android APIs (Google Pay, CameraX, ML Kit), battery optimization, Google Play publishing.

What's included

React Native · Flutter · Single codebase

Cross-platform

One codebase for iOS and Android. React Native (JS/TS) or Flutter (Dart). Times and costs nearly halved compared to native, acceptable performance for 90% of cases.

What's included

PWA · Offline · Push · No store

Web app & PWA

Progressive Web Apps installable from browser, working offline, push notifications, no store constraints. One codebase for all devices, lower times and costs. Perfect to validate an idea without immediately investing in native.

What's included

Approach & method

Apps people actually use.
Not abandoned gadgets.

70% of downloaded apps are uninstalled within 30 days. The difference is made by polished UX, real performance, continuous maintenance.

Native iOS, Android, web app and PWA development

Native UX per platform

On iOS we respect Apple HIG (gestures, transitions, typography), on Android Material Design 3. Users want an app that behaves like the others on their device.

Dedicated & scalable backend

The app is the tip of the iceberg: REST/GraphQL APIs, authentication, database, payment gateway (Stripe, Apple Pay, Google Pay), push notifications, offline sync. Backend sized on real load.

Store publishing & maintenance

Full App Store and Google Play management: developer accounts, store assets, review, updates. Continuous maintenance: bug fixes, evolutions, support for new iOS/Android versions.

Concept · Prototype · Store

Just have an app idea?

Half-day discovery workshop: we figure out whether you need native, cross-platform or PWA, define MVP scope, tell you what order of magnitude is needed and whether building the app makes sense at all. You leave with an action plan.

What's included

What app development
includes

A production app has dozens of technical and non-technical components. Here are the blocks we always manage, on native and cross-platform.

  • Discovery, UX flow & prototype

    User research, user journey, wireframes, interactive prototype (Figma). Validated with real users before development.

  • Stack & platform selection

    Native (Swift/Kotlin), cross-platform (React Native, Flutter), PWA. Choice based on required performance, hardware access, budget, time to market.

  • Dedicated custom backend

    REST/GraphQL APIs, authentication (OAuth, social login, MFA), SQL/NoSQL database, queues, schedulers, webhooks. Backend Node.js/PHP/Python, cloud deployment (AWS/Azure/GCP).

  • Auth, payment & in-app purchases

    Email/password login, social login (Apple, Google, Facebook), MFA, magic link. Payments via Stripe, Apple Pay, Google Pay. In-app purchases: StoreKit (iOS), Play Billing (Android).

  • Push notifications & offline mode

    Push via Firebase Cloud Messaging / Apple Push Notification. Offline sync with service workers (PWA) or local databases (SQLite, Realm). The app works even on the subway.

  • Automated tests & CI/CD

    Unit tests, integration tests, UI tests (XCTest, Espresso, Detox). CI/CD with Fastlane, Bitrise, GitHub Actions: automatic builds, TestFlight distribution.

  • Store publishing & monitoring

    Full management of Apple Developer Program ($99/year) and Google Play Developer ($25 one-time), store assets, review, updates. Monitoring: Crashlytics, Sentry, Analytics.

Frequently asked questions

FAQ about iOS, Android
and PWA app development

Native app or web app?

Depends. Native if you need extreme performance, hardware access (GPS, camera, sensors) or store presence. Web app/PWA if you need an app-like experience without store constraints, with lower costs and a single codebase.

How much does app development cost?

A simple PWA from €2,000, a native MVP from €4,500, a full production app €12,000-30,000, enterprise above. Separate iOS and Android development costs roughly twice as much as cross-platform.

Do you publish on App Store and Google Play?

Yes. For iOS we manage Apple Developer Program enrollment ($99/year), store assets, App Store review. For Android, Google Play Developer ($25 one-time), AAB bundle, Play Store review. Continuous updates too.

Does it work offline?

Yes if needed. Native apps inherit it. For PWAs we use service workers, strategic caching and deferred sync when connectivity returns.

Native, cross-platform or PWA?

Native (Swift/Kotlin) for maximum performance and full hardware access. Cross-platform (React Native, Flutter) to halve costs across iOS+Android. PWA when notifications and installation are enough, without store constraints.

How do you handle auth and payments?

Auth with email/password, social login (Apple, Google, Facebook), magic link, MFA. Payments via Stripe, PayPal, Apple Pay, Google Pay. For in-app purchases: StoreKit (iOS) and Google Play Billing (Android).

And maintenance after launch?

OS updates (iOS/Android change every year), bug fixes, crash monitoring, evolutions. There's always a maintenance plan: the app isn't left to itself.

Can I start with a PWA and then go native?

Yes, it's a strategy we recommend. PWA to validate the idea on the real market with contained costs, then if KPIs justify the investment we move to native.
