We design and build cross-platform mobile apps with Flutter: one codebase for Android and iOS, a native feel on both, and a secure back end that grows with your users.

Problems we solve
Many businesses need an app on both Android and iOS but can't justify two separate teams, two codebases and two release schedules.
Separate Android and iOS apps mean every feature is designed, built, tested and fixed twice.
One platform gets updates first, and users on the other notice the gaps and complain.
Some cross-platform apps feel sluggish, so users uninstall them after the first try.
The app looks fine in a demo but has no secure API, admin panel or way to scale when users arrive.
Our solution
Flutter lets one team ship Android and iOS apps together. We pair it with good design, a solid back end and real-device testing so the result feels native on both.
Most of the code is shared, while navigation, gestures and platform details follow Android and iOS conventions so the app feels at home on each.
We design the API, database, authentication and admin panel with the app, so it's secure and ready to scale from launch.
We test on a range of real Android phones and iPhones, including older and budget models your users actually own.
Flutter app development services
Flutter app development covers design, development, back end, release and support. These are the Flutter development services we offer.
Android and iOS apps built from one Flutter codebase, designed around your users and your business goals. We handle design, development, API integration, testing and the release to both app stores.
A focused first version of your app to test with real users, built on a foundation you can keep extending instead of rebuilding.
Apps for field teams, dealers, customers and staff, connected to your CRM, ERP or internal systems, with role-based access and offline support where needed.
The server side every app needs: APIs, databases, authentication, file storage, notifications and a web admin panel to manage users and content.
Move from two separate native apps, or an old hybrid app, to a single Flutter codebase, planned so users get a smooth update rather than a disruptive switch.
Keep your app working as Android, iOS and Flutter change: updates, security fixes, new features and store compliance every month.
What you get
An app is worth building only if people keep using it. These are the outcomes we design for.
Android and iOS released and updated together, from one codebase.
Fast start-up, smooth scrolling and quick screens on everyday phones.
One codebase means new features reach every user sooner.
Secure authentication, encrypted connections and careful data handling.
Analytics and crash reporting show what users do and where they struggle.
Code, store accounts, designs and data in your company's name.
Why us
Classify-X, Social Sphere CRM, ZeroVault and ZOC Link are designed, built and run by our team.
One team builds the app, API, admin panel and cloud set-up.
A proposal with scope, deliverables and a customised quotation before work starts.
Product design, development, testing and app store submission in one team.
A free strategy call, then a written proposal with a customised quotation.
Our approach
Every app is different. The way we build one isn't. Open each step to see what it covers.
We define your users, the core journey, platform requirements and how the app fits your business.
Flows and screens designed for both platforms, tested as a clickable prototype before development.
State management, API design, data storage, offline needs and integrations, agreed in writing.
App and back end built in short sprints, with test builds you can install on your own phone.
Real-device testing on Android and iOS, then store listings, review and release.
Monitoring, updates for new OS versions, and new features based on how people use the app.

Flutter vs React Native vs native
Flutter, React Native and fully native development each have strengths. This is how they compare.
| Criteria | Flutter | React Native | Native (Kotlin and Swift) |
|---|---|---|---|
| Codebase | One codebase for Android and iOS | One codebase for Android and iOS | Two separate codebases |
| Look and feel | Consistent custom UI on both platforms | Uses native UI components | Fully native on each platform |
| Performance | Smooth for most business and consumer apps | Good for most apps | Best for heavy graphics and device-intensive apps |
| Development effort | One team, one release cycle | One team, one release cycle | Two teams or double the work |
| Device features | Wide plugin support, native code when needed | Wide library support, native code when needed | Full, immediate access |
| Best for | Most business, startup and consumer apps | Teams already invested in React | Games, AR and apps that push the hardware |
We'll recommend the approach that fits your app. Flutter is our default for most cross-platform projects.

Guide
Flutter is an open-source framework from Google for building apps for Android, iOS, the web and desktop from a single codebase, written in the Dart programming language.
Unlike some cross-platform tools, Flutter draws its own interface, so the app looks and behaves consistently on every device. When an app needs a device feature, Flutter can call native Android and iOS code.
The main reason is efficiency: one team builds and maintains one codebase for both platforms, so features reach Android and iOS users at the same time.
Flutter apps also perform well for most business and consumer use cases, and its rich set of interface components makes it practical to build a polished, branded design.
Both build Android and iOS apps from one codebase. Flutter renders its own consistent interface and uses Dart; React Native uses native components and JavaScript or TypeScript.
Flutter is a strong default for most new apps. React Native can make sense if your team already works heavily in React. Either way, the quality of design, architecture and testing matters more than the framework.
Fully native apps in Kotlin and Swift are the better choice for games, augmented reality, apps that push the camera or sensors hard, or products that must adopt brand-new platform features on day one.
For most business, startup and e-commerce apps, a cross-platform approach like Flutter delivers what users need with less effort.
Apps rarely work alone. They need a back end with APIs, a database, secure authentication, file storage, push notifications and, usually, a web admin panel for your team.
Planning the back end with the app avoids security gaps and makes it easier to add a website or web app on the same data later.
Both stores review apps against their policies, including privacy declarations, data use and content rules. Preparing store listings, screenshots and privacy details early avoids delays at release.
Developer accounts should be registered in your company's name, so you keep control of the app and its reviews.
Android and iOS release new versions every year, and stores update their requirements. Apps need regular updates to stay compatible, secure and listed.
Crash reporting and analytics show where users struggle, so each update improves the experience instead of only adding features.
Flutter app costs vary with the number of screens and user roles, custom design, back-end and admin needs, integrations such as payments or maps, offline support, device features, testing, store release and ongoing support.
Because these differ so much between apps, we don't publish fixed prices or packages. After a scoping call, we send a written proposal with the scope, deliverables and a customised quotation.
