Custom Flutter app development for iOS, Android & Web.
We build high-performance Flutter apps from a single codebase — for startups, SaaS founders, and construction tech companies that need to ship fast without doubling their budget.
The short answer
Flutter is Google’s open-source UI toolkit for building natively compiled apps from a single codebase. Unlike React Native—which bridges JavaScript to native components—Flutter compiles directly to native ARM code and renders every pixel using its own Impeller 2.0 engine. The result is 60–120fps performance, pixel-perfect UI fidelity across platforms, and zero rendering surprises.
Bolder has been building production Flutter apps since 2019. We use it for cross-platform mobile apps, SaaS dashboards, construction field tools, and on-demand marketplaces—anywhere you need consistent UI and performance across iOS, Android, and web without maintaining three separate codebases.
The conversations that bring Flutter projects to Bolder.
Real scenarios that bring Flutter projects to Bolder. If one of these sounds familiar, we’ve solved it before.
Cross-platform mobile apps
One Flutter codebase for iOS and Android. Ship to both stores in the same sprint, with pixel-perfect UI and 60fps performance.
Flutter expertise that goes beyond the surface.
We don’t just know the Flutter API. We understand the architecture decisions that make Flutter apps scale, and the performance patterns that separate good apps from great ones.
Custom UI & Animation Systems
We build bespoke widget systems and animation pipelines using Impeller 2.0. No off-the-shelf component libraries — everything matches your brand and performs at 60–120fps.
