Flutter app development for iOS and Android at once
Flutter lets you ship one app to iOS, Android and the web from a single codebase, with native performance and a polished, consistent design. Adivantech offers Flutter app development services for startups and businesses that want to launch on both stores faster and keep maintenance costs down.
As a cross-platform mobile app development company, we also build with React Native when it is the better fit, and we will tell you honestly which framework suits your product. Either way you get weekly demos, direct founder access and support after launch.

Flutter app development cost
Because Flutter shares one codebase across platforms, it usually costs noticeably less than building separate native iOS and Android apps. We quote after the free consultation, based on:
Number of screens & features
The main driver of effort; we help you prioritise what goes into the first release.
Platforms targeted
iOS and Android are the default; adding web or desktop needs extra layout and testing work.
Backend
Firebase is quick to start with; a custom backend fits complex business logic and integrations.
Native features
Bluetooth, background location or custom native SDKs need platform-specific code.
Frequently asked questions
What is Flutter app development?+
Flutter is Google's open-source framework for building apps for iOS, Android, web and desktop from one codebase written in Dart. Flutter app development means building your app once and releasing it on all those platforms.
Is Flutter good for business apps?+
Yes. Flutter delivers smooth, native-like performance and consistent design across platforms, which makes it a strong choice for most business, e-commerce, booking and service apps.
Flutter or React Native: which should I choose?+
Both are mature cross-platform options. Flutter excels at custom, polished interfaces and consistent behaviour; React Native suits teams already using React and JavaScript. We recommend one after understanding your product.
Is a cross-platform app cheaper than native?+
Usually yes. One codebase means less development and maintenance than two separate native apps, which typically lowers both launch and long-term costs.
Can you take over my existing Flutter app?+
Yes. We review the code, fix urgent issues, upgrade dependencies and continue development, with a clear report of what we found.
