Client Stories

What Our Clients Say

We launched on iOS, Android and Web simultaneously in under 5 months. The Flutter UI animations are genuinely the most beautiful I've seen in any of our competitor apps.

L
Lena Fitzgerald
CPO, Luminary EdTech

The custom widgets Appther built are works of art. Our users constantly ask how we made it look so good — Flutter's rendering engine in expert hands is genuinely next-level.

R
Ravi Kapoor
Founder, DesignFlow Studio

We needed a desktop app for Windows, Mac and Linux plus iOS and Android. Appther delivered all five from one Flutter codebase — the ROI compared to five separate builds is enormous.

FAQ

Flutter Development — Common Questions

Both are excellent for cross-platform development. Flutter has an edge in UI consistency and animation quality — it owns its rendering engine (Impeller), so pixels look identical on all platforms. React Native leverages native components, which can feel more "at home" on each platform. The best choice depends on your team's background, UI complexity and whether you need desktop/web support. Flutter excels when beautiful, consistent UI is a priority.
Yes — Flutter 3.x officially supports iOS, Android, Web, Windows, macOS and Linux from a single Dart codebase. Shared code typically runs 85–95% unchanged across platforms. We handle platform-specific adaptations (navigation patterns, window sizing, native integrations) through adaptive layouts and platform channels.
Dart is Google's programming language that powers Flutter. As a client, you don't need to know Dart — we handle all the development. It's a statically-typed, compiled language with a syntax similar to Java and JavaScript. Developers with JavaScript or Java experience typically learn Dart quickly. We write clean, documented Dart so your future team can maintain it easily.
Flutter compiles to ARM machine code (not interpreted) and uses its own Impeller rendering engine targeting 120fps on supported hardware. For UI-heavy apps, Flutter often outperforms React Native and matches native in most real-world benchmarks. The only scenarios where native has a clear edge are highly specialized hardware access (deep GPU work, AR frameworks) requiring platform-specific native code.
A focused Flutter MVP targeting iOS and Android takes 6–10 weeks. A full-featured consumer app with backend, payments and integrations takes 3–5 months. Enterprise multi-platform apps (including Web and Desktop) run 5–8 months. All timelines are for simultaneously shipping all target platforms — there's no "then we do iOS, then Android" phase.
We primarily use Riverpod 2.x — Google's recommended solution for Flutter in 2024. It provides excellent compile-time safety, no BuildContext dependency and scales from simple apps to enterprise complexity. For teams with existing BLoC experience or GetX preferences, we adapt — the architecture decision is made per project, not enforced across all clients.
