Is Flutter right for your app?
Flutter is a strong fit when you need parity across iOS and Android without doubling engineering headcount. It is not the right call for every project. The boxes on the right cover when we recommend it, and when we point clients elsewhere.
Startups validating an idea on iOS and Android
If you need both stores live before the next funding milestone, Flutter is the fastest path with one team and one codebase.
Brands that need pixel-identical UI everywhere
Flutter renders its own widgets through Skia and Impeller, so buttons, type, and motion look the same on a Pixel and an iPhone. Useful when design parity matters more than platform conventions.
Teams cutting mobile maintenance cost
Two native codebases mean two release trains, two QA cycles, and two specialist hires. One Dart codebase compresses that overhead while keeping full App Store and Play release control.
What we deliver in a Flutter build
We ship apps, not framework demos.
Native-feel UI and steady 60fps
Flutter apps that hold a steady frame budget on mid-range Android and high-end iOS. We profile with DevTools, use const widgets where they matter, and avoid the patterns that cause jank in production.
1Codebase. Both platforms. Same day.
Pixel-accurate Figma to Flutter
Designs translated to widgets without the "framework can't do that" excuse. Custom painters, animation curves, and motion specs land the way the designer drew them.
50%Average cost saving vs maintaining two native codebases
Architecture that survives feature growth
Riverpod or BLoC, repository pattern, isolated business logic, and folder structures that still make sense at sprint 30. Picked per project, not as one-size-fits-all dogma.
100%Design spec fidelity – measured at client sign-off
Native integration via platform channels
Bluetooth, ARKit, MLKit, secure storage, in-app purchases. We write the platform channels and Swift or Kotlin glue when the package ecosystem stops short.

Flutter problems we fix
We rescue stalled Flutter builds and clean up performance debt.
The Problem
Janky scrolls and dropped frames
Bad rebuild patterns and rendering on the wrong thread cause UI freezes during scroll-heavy lists and image grids.
Tangled state management
Untraceable bugs from state passed through fifteen widget layers, with no clear source of truth.
Bloated APK and IPA sizes
Apps shipping at 150MB+ because assets are not lazy loaded and unused packages are not tree-shaken.
Our Solution
Profiled rebuild graph, const where it matters
We open DevTools, find the widgets rebuilding too often, and fix the cause. Const constructors and Selector or Consumer scopes do the rest.
Riverpod or BLoC with clean boundaries
Business logic out of widgets, dependency injection through Provider Scopes or Modules, and tests that do not need a full widget tree.
Asset pruning and split ABIs
Lazy-loaded assets, font subsetting, split APKs by ABI, and an audited dependency tree. Sub-25MB downloads are normal.

Why reverseBits for Flutter?
We are a focused Flutter team that takes apps from architecture decisions through App Store release. We have opinions on state management, on the package ecosystem, and on which fights to pick with the platform.

Flutter questions, answered.
Common questions about Flutter projects.
Ready to build your Flutter product?
Yes, when it is built right. Flutter renders its own widgets to ARM-compiled native code via Skia or Impeller, which means animations, scrolls, and transitions run on the GPU like a native app does. The places where users notice cross-platform tax are usually keyboard handling, system sheets, and platform-specific gestures. We map those to Cupertino on iOS and Material on Android so the app feels at home on both.
We use Riverpod or BLoC, picked per project. Riverpod for apps where most state is reactive and dependency-graph driven. BLoC where the team is already comfortable with event-driven streams or wants a clear separation between UI events and state transitions. Either way, business logic lives outside widgets, repositories sit between state and data sources, and the widget tree subscribes to the slices it needs.
Yes. Pub.dev covers most needs (camera, BLE, biometrics, in-app purchase, push). When a package does not exist or the existing one is unmaintained, we write platform channels in Swift or Kotlin and expose a clean Dart API. We have done this for hardware peripherals over BLE, secure enclave operations, and SDKs that ship as native frameworks only.
Yes. We set up Fastlane or Codemagic wired into your branch model so a tagged commit builds the iOS and Android binaries, signs them with the right certificates, and uploads to TestFlight and Internal Testing automatically. Production rollouts (phased on Play, App Store review submission) stay a manual approval step on purpose.
Most of our Flutter apps use Firebase (Auth, Firestore, Cloud Functions, FCM) when the team wants a managed BaaS, or a custom Node.js, FastAPI, or NestJS backend when the data model and business rules need more control. Flutter does not care what the API looks like, so we pick the backend based on what the product actually needs.
Mostly yes, with caveats. Google Maps and Mapbox both have official Flutter SDKs that handle markers, polylines, custom styles, and live location well. Where Flutter falls short is when you need deep platform-specific map features (such as iOS-only CarPlay map extensions or specific MapKit overlays), in which case we wrap the native view in a PlatformView or split the navigation surface out as a native module.
