Hire Flutter Developers — Cross-Platform iOS & Android Apps
Reading time: 3 minutes.
Hire Flutter Developers — iOS & Android from One Codebase
Flutter lets you ship to iOS and Android from a single Dart codebase without the compromises that plagued earlier cross-platform frameworks. Google’s widget rendering engine gives you frame-perfect animations and custom UI that React Native can’t achieve without native modules.
CimpleO builds Flutter apps for consumer products, enterprise field tools, and IoT companion apps — from discovery and design through App Store and Play Store delivery.
What We Build With Flutter
Consumer Apps Apps with smooth animations, onboarding flows that convert, and UX patterns that reduce churn. We design for the touch interaction model from the start — not as a mobile adaptation of a desktop UI.
Enterprise & Field Apps Offline-first Flutter apps with background sync, barcode/QR scanning, digital signature capture, form workflows, and integration with back-office systems (ERP, CRM, WMS). Built for environments where connectivity is intermittent and the app must work regardless.
IoT Companion Apps Flutter apps that connect to hardware via Bluetooth Low Energy, display live sensor data, configure device parameters, and push firmware updates OTA. We build the mobile layer alongside the firmware — one team, no integration hand-offs. See our IoT Engineering service for the full stack.
Data-Heavy Dashboards Apps that display complex time-series data, interactive charts, filterable tables, and configurable widgets. Flutter’s canvas-based rendering handles custom visualisations that platform-native components make difficult.
Our Process
Discovery (Week 1): User flows, screen inventory, feature prioritisation, and technical architecture. You review a clickable Figma prototype before development starts.
Development (Weeks 2–N): Feature-by-feature, with weekly builds delivered to TestFlight and Google Play internal track. You test on real devices throughout, not at the end.
Release: App Store and Play Store submission, metadata and screenshots, review process management, and launch monitoring.
State Management & Architecture
We use Riverpod or Bloc depending on app complexity. Riverpod for most apps — composable, testable, and without the boilerplate of older Redux-inspired patterns. Bloc where the team has existing familiarity or the state graph is complex enough to warrant explicit event streams.
Architecture: Clean Architecture layers (data, domain, presentation) for apps with complex business logic; simpler feature-first structure for MVPs where over-engineering is the risk.
Stack
- Core: Flutter 3.x, Dart, Material 3 / Cupertino

Frequently Asked Questions
Flutter or React Native — which should we choose?
Flutter for pixel-perfect custom UI and animations — Dart compiles to native ARM code, giving consistent frame rates. Flutter's widget system gives you full control over every pixel without platform-native component constraints. React Native for JavaScript/TypeScript teams who want to share logic with a web frontend. We build with both; choose based on your team's existing skills and UI complexity requirements.
How long does a Flutter app take to build?
A Flutter MVP (core features, two platforms, App Store submission): 8–14 weeks. A production-grade consumer app with backend, push notifications, and in-app purchases: 4–6 months. Timeline depends on feature complexity, design completeness at start, and backend availability.
How much does Flutter development cost?
A focused MVP: $30,000–$60,000. A full consumer or enterprise app: $60,000–$150,000+. These include design, development, testing, and App Store/Play Store submission. Backend development is separate if you don't have one.
Do you handle App Store and Google Play submission?
Yes — fully. Provisioning profiles, signing certificates, App Store Connect and Google Play Console setup, review guidelines compliance, and submission. If an app gets rejected, we handle the response and resubmission.
Can Flutter access native device features?
Yes. Flutter has plugins for most device capabilities: camera, GPS, Bluetooth, NFC, biometric auth, local notifications, and background processing. For capabilities without an existing plugin, we write platform-specific code in Swift (iOS) and Kotlin (Android) and bridge it to Dart.
Do you include app design, or just development?
Design is included. You get Figma screens and an interactive prototype before development starts. We don't hand you a repo and tell you to figure out the UI.
