Flutter apps,
pixel-perfect on both stores

A Flutter app development company designs, builds, and ships production mobile apps using Flutter — a single Dart codebase that renders its own pixel-consistent UI on both iOS and Android. Beyond building the app, that means platform-channel work where native APIs are needed, store submission, performance tuning, and ongoing maintenance. At Idealogic it is senior engineers who have shipped Flutter apps to both stores, not a team learning the framework on your budget.

Flutter cost is driven by scope — screens, integrations, and the amount of native and backend work — rather than a fixed price. A focused MVP starts lower and a complex, integration-heavy app costs more, and we scope it precisely before any commitment. The full breakdown is in our mobile app development cost guide.

Yes. Flutter runs in production at scale — Google, BMW, and Alibaba among others — and its own rendering engine gives it smooth, consistent performance and identical UI across platforms. It's a strong fit for most apps, and especially design- and motion-heavy ones; the main trade-offs are a smaller talent pool than React Native and larger app binaries, both manageable for most products.

Both are excellent, and the right pick depends on your team and product. Flutter wins for the most design- and animation-heavy UIs and pixel-identical branding across platforms; React Native wins when you already have React and TypeScript skills or want to share code with a web app. We compare them in depth in our React Native vs Flutter guide, and we build in both.

Yes. We take over existing Flutter codebases to fix, extend, and ship them, beginning with an audit of the architecture, state management, and platform channels, since that is where stalled projects usually hurt. Whether you need to rescue a stalled build, add features, or harden it for scale, we work from your current code rather than starting over.

A typical Flutter MVP reaches the stores in about 8 to 14 weeks, with larger or integration-heavy apps taking longer; the single codebase is part of why cross-platform is faster than building two native apps. We stage delivery so a real, testable build is in your hands early and grows from there.

Most of our Flutter work falls into a few shapes: building a new iOS and Android app from one codebase, taking an MVP from idea to the stores, and migrating separate native apps onto a single Flutter codebase. We also rescue stalled or inherited builds, extend the same codebase to web and desktop where it fits, and do the custom UI and motion work Flutter is best at. If you're not sure which one you need, that's a normal first call.
