Mobile app development company for iOS and Android
We design, build and launch native and cross-platform apps in Swift, Kotlin, Flutter and React Native, together with the backend, admin panel and analytics behind them.
ZedBlu is a mobile app development company that takes an app from idea to the App Store and Google Play, then keeps it healthy after launch. We handle product design, iOS app development, Android app development, the backend APIs and the admin panel your team uses to run the app day to day.
Every mobile project starts with a key decision: native or cross-platform? We use Flutter or React Native when one codebase can deliver the experience you need on both platforms, and Swift or Kotlin when the app depends on heavy device integration, complex animation or platform-specific features. You get the trade-offs explained in plain terms before you commit.
Our apps run real operations. ZedBlu's own PestOS platform includes a technician app with GPS tracking and a white-label app that pest control companies can offer under their own brand, and the Android and iOS apps of The Hawk and Dainik Hawk share one backend with their news websites and ePaper. Those builds shape how we plan offline use, notifications and releases for your app.
What our Mobile App Development team delivers
Cross-platform apps with Flutter
One codebase for iOS and Android with near-native performance and a consistent interface on both. Flutter suits most business, commerce and on-demand apps and shortens the path to both stores. As a Flutter app development company, we structure state management and feature modules so the app stays maintainable as it grows.
React Native development
A strong fit when your team already works in React or TypeScript, or when you want to share logic with a web app. Our React Native app development covers custom native modules where needed, over-the-air updates for JavaScript changes and a shared design system across mobile and web.
Native iOS apps in Swift
For apps that rely on Apple-specific capabilities such as HealthKit, widgets, Apple Pay, background processing or advanced camera work, we build natively in Swift. We follow Apple's Human Interface Guidelines and plan for App Store review requirements from the first sprint.
Native Android apps in Kotlin
Kotlin apps for performance-sensitive or hardware-heavy use cases: Bluetooth devices, barcode scanning, offline-first field work or a wide range of budget devices. We test across the screen sizes and Android versions that matter in your target markets, not just the latest flagship phones.
Backend, APIs and admin panels
Every app needs a backend for user accounts, data, payments and notifications, plus an admin panel for your team. We build it in Node.js, Python or Laravel, or use Firebase where it fits, and design APIs that a future web app or partner integration can reuse.
UI/UX design for mobile
Wireframes, clickable prototypes and a design system covering both platforms. We test key flows such as sign-up, checkout or booking with real users early, because fixing a confusing screen in a prototype costs far less than rebuilding it in code.
Store launch and release management
We prepare store listings, screenshots, privacy disclosures and signed builds, then manage submission to the App Store and Google Play. If a review is rejected, we resolve the issue and resubmit. Crash reporting, analytics and staged rollouts are configured before your first public release.
App maintenance and upgrades
Apple and Google release new OS versions and policy changes every year. We keep your app compatible, update dependencies, fix crashes and add features through a monthly support plan, so the app does not quietly break between major releases.
What you get
The right technology for each app
We do not push one framework. Flutter, React Native, Swift and Kotlin each have strengths, and we recommend one based on your features, budget, team skills and long-term roadmap, with the reasoning written down.
One team from design to backend
Design, mobile, backend and DevOps work in the same team, so API changes, screens and release plans stay in sync and you are not coordinating three vendors.
Built for real-world conditions
Weak networks, older phones and interrupted sessions are normal. We design offline caching, retry logic and lightweight screens so the app works where your users actually are, not just on office Wi-Fi.
Your accounts, your code
You own the source code, signing keys and store listings, published under your own developer accounts. Build and release steps are documented so your team or another vendor can take over without depending on us.

Mobile App Development: FAQ
How much does it cost to build a mobile app?
The cost of mobile app development typically ranges from $10,000 to $80,000+, depending on the number of screens and user roles, integrations, backend complexity and whether you need native or cross-platform apps. One Flutter app for both platforms usually costs less than two separate native apps. After a free consultation we give you a fixed quote or an itemized estimate broken down by feature.
How long does mobile app development take?
A focused first version typically takes 10–16 weeks: two to three weeks for discovery and design, then development, testing and store submission. Apps with complex backends, payments, real-time tracking or many user roles take longer, and store review can add a few days. Your proposal includes a milestone plan, and weekly test builds show progress against it.
Should I choose Flutter, React Native or native development?
Choose Flutter or React Native when you want one codebase for iOS and Android and your app relies on standard features such as forms, lists, maps, payments and notifications. Choose native Swift and Kotlin when performance, device hardware or platform-specific features are central. Cross-platform app development usually lowers cost and speeds up delivery, and we recommend an approach after reviewing your feature list.
Can I hire mobile app developers to join my team?
Yes. If you already have a product manager or CTO, you can hire mobile app developers from ZedBlu who work inside your sprints and tools as a dedicated team, with daily overlap in your time zone. Developers are senior, the team can grow or shrink with your roadmap, and all code is committed to your repository.
Will you publish the app on the App Store and Google Play?
Yes. We prepare listings, screenshots, privacy labels and compliance details, then submit under your own developer accounts so you keep full control. We handle reviewer questions and any rejections. Publishing under your accounts also means ratings, reviews and download history stay with your brand if you ever change vendors.
How do I choose the right mobile app development company?
Look at apps they have shipped and still maintain, who will actually write your code, how they handle changing requirements and who owns the result. At ZedBlu, senior engineers build your app, you see a working build every week, we sign an NDA before kickoff and the code and IP are 100% yours. Ask any vendor for a detailed proposal first; ours arrives within 48 hours.
