iOS / Android

Two platforms, one codebase, zero compromise.

We specialize in crafting high-quality mobile apps for both iOS and Android, ensuring seamless performance and user experience through Flutter and React Native development. By leveraging a single codebase, we guarantee lower development and maintenance costs.

Start Your App
iOS and Android app development delivers mobile applications to Apple and Google app stores. Moddtech builds cross-platform apps using Flutter and React Native — shipping to both platforms from one codebase with native-quality UI and performance.
Who it's for
Founders launching consumer apps on both platforms, businesses with limited mobile development budgets, and teams maintaining legacy native apps that need modernization. Especially well-suited for teams already invested in JavaScript/React (React Native) or design-heavy products that need pixel-perfect consistency (Flutter).
  • Ship to Apple App Store and Google Play from one codebase
  • Build with Flutter or React Native — whichever fits your project
  • Cut development time by up to 40% vs separate native builds
  • Maintain one app, not two, long-term
  • Access every native feature through Flutter plugins or React Native modules
Process

How it works, step by step

01
Strategy & Scoping
Platform strategy, feature prioritization, and technical architecture. Outcome: a clear MVP scope and launch plan.
02
Design
UX flows and UI design in Figma — respecting iOS and Android conventions where appropriate. Prototypes for stakeholder review before code.
03
Cross-Platform Development
Clean architecture in Flutter (Dart) or React Native (TypeScript), reusable components, and platform channels for native-only features. Backend APIs, auth, push notifications, and analytics integrated along the way.
04
QA & App Store Prep
Testing on real iOS and Android devices, TestFlight and Play Console beta distribution, store assets, and submission.
05
Launch & Iteration
Post-launch monitoring via Sentry and analytics. Iterate on user feedback with over-the-air updates where possible.

FAQ

Questions we hear most often.

Don't see what you're looking for? Ask us directly — bilingual response within one business day.

Should we use Flutter or React Native?

Depends on your team and project. Flutter (Google's framework, built in Dart) excels at custom UI, animations, and design consistency. React Native (Meta's framework, built in JavaScript) is best when your team knows React, or when you're sharing code with a web app. Both compile to native, both perform near-native, and both ship to App Store and Google Play.

Will cross-platform apps feel native on iOS and Android?

Yes. Both Flutter and React Native provide platform-aware widgets — Material design for Android and iOS-style for Apple. We design for platform parity where it makes sense and platform specificity where it matters.

Can these apps access iOS and Android hardware features?

Yes. Camera, GPS, Bluetooth, biometric auth, push notifications, background tasks, and Apple Pay / Google Pay all work through official Flutter plugins or React Native modules — or custom native code through platform channels when needed.

What about the backend?

We typically build serverless backends on AWS (Lambda, API Gateway, DynamoDB) or use Firebase for MVPs. Authentication via Firebase Auth, Auth0, or AWS Cognito. The backend is framework-agnostic — your mobile app just consumes APIs.

How do you handle app store submissions?

We manage both App Store and Google Play submissions end to end — screenshots, ASO metadata, privacy declarations, and review responses. We've been through the process many times.

Can you take over an existing Flutter or React Native project?

Yes. We audit the codebase, identify technical debt, and propose a transition plan. We've taken over both Flutter and React Native projects from other teams — many of our ongoing clients started with someone else.

Cross-platform done right — Flutter or React Native

Building separate iOS and Android apps used to mean two codebases, two teams, and two maintenance budgets. Modern cross-platform frameworks changed that. Moddtech ships in both Flutter and React Native, recommending whichever fits your project's tech stack, team skills, and performance requirements.

Flutter for native-quality UI at scale

Flutter is Google's modern cross-platform framework. It compiles to native code and renders its own UI layer, delivering native-quality performance from one Dart codebase. Best when you want maximum design control, animation-heavy UIs, or pixel-perfect consistency across platforms.

React Native for JavaScript-first teams

React Native uses JavaScript and React — a strong fit when you already have web developers who know React, or when you want to share code across web and mobile. Mature ecosystem, huge plugin library, and battle-tested at scale by Meta, Shopify, Discord, and others.

Native-feel, cross-platform build

Both frameworks ship with platform-conventional widgets — Material for Android and iOS-style for Apple devices. We mix where it makes sense, giving users the platform conventions they expect. Animations feel right, gestures behave naturally, and platform-specific APIs (biometric auth, Apple Pay, Google Pay) work through mature plugins.

Backends built for scale

Behind every mobile app is an AWS-backed serverless architecture. Lambda functions, API Gateway, DynamoDB, and S3 — all configured for cost-effective scale. Authentication via Firebase Auth or AWS Cognito. Real-time features via WebSockets or Firebase Realtime Database.

End-to-end, not just code

App store submission is its own specialty. We handle ASO metadata, screenshots, privacy declarations, age ratings, and review responses. Launch week includes active monitoring and rapid fixes for any issues that emerge.
