Mobile Apps

Mobile App Development with React Native & Flutter

We are a mobile app development company building cross-platform iOS and Android apps from a single codebase — fast to ship, simple to maintain, and ready for the app stores. When a project truly needs it, we go fully native with Swift and Kotlin.

What we build

Cross-platform apps, native quality

From consumer apps to internal enterprise tools, we own the full journey: product design, development, testing, and submission to the Apple App Store and Google Play.

01

Cross-Platform

One codebase, two platforms. Ship iOS and Android together from a single React Native or Flutter project.

02

Native Performance

Smooth 60fps animations and near-native speed. Users get a fluid, responsive app — not a wrapped website.

03

Push Notifications

Keep users engaged with targeted push via Firebase Cloud Messaging and Apple Push Notification service.

04

Secure by Default

Encrypted storage, hardened auth flows, and a privacy-first architecture baked in from day one.

  • Android & iOS apps from a single codebase
  • React Native & Flutter cross-platform development
  • Native iOS (Swift) & Android (Kotlin) when required
  • UI/UX design and interactive prototyping
  • App Store & Google Play submission and review
  • Push notifications, offline support & background sync
  • Backend APIs, authentication and cloud integration
  • Post-launch maintenance and OS-version updates
Choosing a stack

React Native vs Flutter vs native

There is no single right answer — the best stack depends on your team, your timeline, and how ambitious your UI is. Here is how we guide that decision.

React Native

Best when you already live in JavaScript/TypeScript or want to share logic with a web product. A huge ecosystem, fast iteration, and easy hiring make it our default for most business apps.

Flutter

Best for pixel-perfect, animation-heavy UIs that must look identical on every device. Flutter renders its own widgets, giving you total control over the look and very consistent results.

Native (Swift / Kotlin)

Best when a project leans hard on device hardware, AR, or platform-specific APIs. We build in Swift for iOS and Kotlin for Android whenever native is genuinely the right call.

Launch

App Store & Google Play submission

Building the app is half the job — getting it approved is the other half. We have shipped our own products, including MatrixInn PiP and the WhatsApp Floating Button, so we know exactly what reviewers look for.

  • Store listings, screenshots, and metadata written to convert browsers into installs.
  • App signing, provisioning, and build configuration for both platforms.
  • Privacy declarations and data-safety forms that pass Apple and Google review.
  • Rejection-proofing — we resolve review issues fast and resubmit on your behalf.
How we work

Our mobile app development process

A clear, milestone-driven path from idea to a live app on both stores.

Step 01

Discovery

We map your users, features, and platforms, then pick the right stack — React Native, Flutter, or native — and lock a fixed milestone plan.

Step 02

Design

UI/UX design and clickable prototypes so you can feel the app before a line of production code is written.

Step 03

Build & test

Iterative development with real-device testing, backend integration, and weekly builds you can install and review.

Step 04

Launch & support

We submit to both stores, then keep the app healthy with OS updates, fixes, and new features after release.

FAQ

Mobile app development questions

How much does it cost to build a mobile app?
It depends on scope, but a cross-platform MVP built with React Native or Flutter typically costs far less than two separate native apps because one codebase ships to both iOS and Android. We scope each project up front with a fixed milestone plan so there are no surprises — tell us your feature list and target platforms and we will give you a clear estimate.
React Native or Flutter — which should I choose?
Both are excellent. React Native suits teams already in the JavaScript/TypeScript ecosystem and apps that share logic with a web product. Flutter suits pixel-perfect, animation-heavy UIs and gives very consistent rendering across devices. For most business apps either is a great fit; we recommend the one that matches your team, timeline, and UI ambitions. We break down the trade-offs in detail in our React Native vs Flutter 2026 guide.
Can you build a native iOS or Android app instead of cross-platform?
Yes. We work in Swift for iOS and Kotlin for Android when a project genuinely needs platform-specific capabilities — heavy use of device hardware, AR, or strict native performance requirements. Most apps do not need that, which is why we default to cross-platform, but native is always on the table.
Do you handle App Store and Google Play submission?
We do. We prepare store listings, screenshots, privacy declarations, and signing, then submit to the Apple App Store and Google Play on your behalf. We have shipped our own apps, including MatrixInn PiP and the WhatsApp Floating Button, so we know the review process and how to get approved the first time.
Will my app work offline and send push notifications?
Yes. We build offline-first storage and sync where it matters, and wire up push notifications through Firebase Cloud Messaging and Apple Push Notification service so you can re-engage users with targeted, timely messages.
Do you provide support after the app launches?
Yes. We offer ongoing maintenance — OS-version updates, bug fixes, new features, and store-policy compliance — so your app keeps working as iOS and Android evolve. You can reach us any time at contact@matrixinnsolutions.com.
