Overview

Two Platforms, One Codebase, No Compromise

Flutter lets us build for iOS and Android from a single codebase without the performance compromises of older cross-platform tools. That means faster development and lower long-term maintenance cost, without users noticing the difference.

Flutter App Development: Frequently Asked Questions

Flutter compiles to native ARM code and typically performs very close to fully native apps, with smooth animations and fast startup times.

Yes, Flutter has a mature plugin ecosystem for native device features, and we can write custom native code where a plugin does not exist.

Generally yes, since one codebase serves both platforms, reducing both initial development and ongoing maintenance cost.

Yes, we regularly consolidate separate native codebases into a single Flutter app to reduce long-term maintenance overhead.

Cost depends on feature scope and native integrations needed; get in touch for an estimate based on your specific project.

Flutter uses its own rendering engine, which tends to give more visually consistent UI across iOS and Android, while React Native renders through native platform components and has a larger existing JavaScript ecosystem to draw from. Which one fits better depends on your team's existing skills and how much platform-specific native feel matters for your app u2014 we're happy to talk through the trade-offs for your specific project.

Yes, this is one of Flutter's strengths. Because it renders its own UI rather than relying on native platform widgets, it handles custom animations and pixel-perfect designs particularly well.

Yes, we offer maintenance plans covering OS updates, dependency upgrades, bug fixes, and new feature development across both platforms.
