Mobile App Development

Native-grade iOS and Android apps with Flutter, React Native, Kotlin and Swift. End-to-end support through App Store and Google Play release.

Done Dynamics builds iOS and Android mobile applications end-to-end. We ship native-grade products with Flutter, React Native, Kotlin and Swift, and run the App Store and Google Play release process — certificates, packaging, store optimization, beta distribution and App Review management — for you.

Platforms

iOS, Android and cross-platform — from one team

It does not matter which phone your users carry; the app feels native on both.

iOS

Apple HIG-compliant, native-performance apps for iPhone, iPad and iPadOS. iOS 15 and above.

Android

Material Design 3 apps that run smoothly across Android 8.0 and above. Tablet and Wear OS covered.

Cross-platform

One codebase, both stores — Flutter or React Native to save time and budget while keeping a native feel.

Native

When performance or hardware is critical, we write pure Android in Kotlin and pure iOS in Swift. Fully native experience.

Technology

Flutter, React Native, Kotlin, Swift

We pick from cross-platform to fully native based on the project, not the hype cycle.

Flutter

Dart-based, one codebase for iOS and Android. High FPS, fast iteration, broad package ecosystem. MVP to enterprise.

React Native

Ideal if your team is already JavaScript/TypeScript. Native modules give full access to iOS and Android APIs. Expo and bare workflows supported.

Kotlin

Official Android language. Modern declarative UI with Jetpack Compose. Clean async code with coroutines. Fully native performance.

Swift

Official iOS language. Modern UI with SwiftUI, reactive data flow with Combine. First-class access to ARKit, Core ML and HealthKit.

Offline-first

SQLite, Realm, Hive, Drift. Local store, offline queue, conflict resolution. Work keeps going when connectivity drops.

Backend & APIs

REST and GraphQL services, auth, push notifications (FCM, APNs), realtime (WebSocket, Supabase).

App Store & Google Play

End-to-end release support

Store process is as critical as the code. From certificates and signing to ASO, TestFlight and App Review appeals — every step is run by us.

  • App Store Connect

    Certificates, profiles, App ID setup; bundle configuration; screenshots, description and keyword strategy; TestFlight beta; App Review submission and appeals/responses when rejected.

  • Google Play Console

    Developer account setup, AAB packaging, Play App Signing, listing optimization, closed/open test tracks, production rollout and policy response handling.

  • Store visuals & copy

    Icon, splash, store screenshots, short and long descriptions, keywords, category — done to ASO principles.

  • Post-release operations

    Crash reports, review responses, hotfix releases, release notes, automated delivery pipeline (Fastlane/CI). Publishing is an ongoing operation, not a one-off.

Use cases

What we can build

From consumer apps and field tools to e-commerce and IoT control panels.

Consumer Apps

Loyalty, ordering, booking, catalogue in the pocket — bring your brand to the screen users open every day.

Field & Operations

For technicians, couriers and warehouse staff — barcode, signature, photo report, offline-capable work order apps.

Internal Enterprise

Approvals, leave, notifications, internal catalogue — mobile version of company workflows, always at hand.

E-commerce & Marketplace

Fast checkout, push notifications, personalized home. 2-3x conversion uplift compared to mobile web.

Health & Fitness

HealthKit, Google Fit and wearable integrations for tracking data and goals.

IoT & Hardware

BLE, NFC, camera and sensor integrations. The mobile app as the control panel for your smart hardware.

Why us

A mobile app is your product in the pocket

So we ship more than code: design, ASO, release, analytics and post-release operations from one team.

  • Native look, native speed

    Across Flutter and React Native too, animations stay above 60 FPS — no jank, no lag.

  • One team, four outputs

    The same team delivers iOS, Android, App Store build and Play build. Coordination overhead does not land on you.

  • Accessibility by default

    VoiceOver, TalkBack, dynamic type, color contrast — checked on every screen.

  • Strong brand identity

    Splash, icon set, store visuals and onboarding — the first impression comes before the product.

  • Analytics and crash tracking

    Crashlytics/Sentry, usage analytics and A/B testing wired in at delivery.

  • No vendor lock-in

    Source code and store accounts are yours. You can hand it to another team at any time.

Security

Mobile security — a checklist

Security in a phone is less visible than in a browser; every item is made explicit.

  • TLS 1.3 for server traffic with certificate pinning to block MITM.
  • Sensitive data stored in iOS Keychain and Android Keystore, backed by hardware security modules.
  • Biometric auth (Face ID, Touch ID, Android Biometric) ready out of the box.
  • Code obfuscation (R8/ProGuard, Swift symbol stripping) to harden against reverse engineering.
  • OWASP Mobile Top 10 and MASVS aligned security review.
  • KVKK & GDPR aligned consent, retention and deletion flows included.
Process

From idea to store release

Five phases, each with visible output.

  1. 01

    Discovery & Targeting

    Target audience, platforms, success metrics and store requirements decided together.

  2. 02

    Design & Prototype

    iOS HIG and Material Design 3 applied in parallel. Clickable prototype tested with users.

  3. 03

    Architecture & Stack

    Native (Kotlin/Swift) vs cross-platform (Flutter/React Native) — chosen by performance, team and timeline constraints.

  4. 04

    Development

    TDD, code review and continuous integration. Weekly beta builds via TestFlight and internal track.

  5. 05

    Release & Operations

    App Store and Google Play submission, rejection handling, ASO. Post-launch analytics, crash monitoring and release roadmap with you.

FAQ

Mobile App Development — FAQ

Do you build separately for iOS and Android? +

Depends on the project. If performance or hardware access is critical we write pure native Swift (iOS) and Kotlin (Android). If time and budget come first we ship both stores from one codebase using Flutter or React Native.

Is App Store and Google Play publishing included? +

Yes. Developer account setup, certificates/profiles, bundle signing, store listings, screenshots, ASO, TestFlight beta, App Review submission and rejection handling are all run by us.

What if our submission is rejected? +

We analyze the rejection reason from Apple/Google, make the required changes, and file written appeals to the review board when needed. Re-submission after rejection is included in the package.

Which devices and OS versions do you support? +

Default targets are iOS 15+ and Android 8.0 (API 26)+, covering 95%+ of global users. Older versions are possible with extra engineering.

Can the app work offline? +

Yes. Local store (SQLite, Realm, Drift), offline queues, conflict resolution and background sync — offline-resilient apps are part of our default capability.

Are push, payments, maps and other integrations included? +

Yes. FCM and APNs push, Apple/Google Pay, Stripe, iyzico, PayTR, Google Maps, Mapbox, OneSignal, Branch, RevenueCat, Sentry, Mixpanel and similar integrations are part of the package.

Who owns the source code and store accounts? +

Source code, store accounts and signing keys are contractually yours. No vendor lock-in.
