Cross-Platform iOS & Android Apps
Single Flutter codebase deployed to both Apple App Store and Google Play. Native performance, native feel, platform-specific UI conventions respected.
Flutter Mobile App Development
One Codebase. Two App Stores. Native Performance on Both.
Flutter lets us build a single, beautifully designed application that runs natively on iOS and Android — cutting your development budget in half without cutting corners on user experience. We've shipped Flutter apps to users across 4 continents.

Service Overview
A clear look at what this service covers, how we approach delivery, and where it creates the most value.
Building separate iOS and Android applications historically meant two codebases, two development teams, and two sets of bugs. Flutter — Google’s cross-platform UI framework — changes that equation. A single Dart codebase compiles to native ARM code for both platforms, delivering performance indistinguishable from fully native applications.
At Mavin Agency, our Flutter team has shipped mobile applications across fintech, SaaS, health and wellness, and eCommerce verticals. We specialise in Flutter apps that integrate deeply with existing web backends — whether that’s a Laravel API, a Firebase backend, or a third-party service layer. Our apps look premium, perform natively, and launch on both stores within your timeline.
Deliverables
What We Deliver
Architecture, integrations, performance, and release-ready execution — without unnecessary scope fluff.
Fintech & Mobile Money Apps
Secure financial applications with biometric authentication, M-Pesa/Paystack/Flutterwave integration, real-time transaction feeds, and offline-tolerant data sync.
SaaS Companion Apps
Mobile interfaces for existing web SaaS products. Flutter apps that consume your existing Laravel or Node.js API — consistent data, platform-native experience.
eCommerce Mobile Apps
Flutter shopping apps with WooCommerce or Shopify backend integration, Apple Pay / Google Pay, push notifications, and product catalogue performance tuned for large inventories.
Flutter Web (Optional)
Some applications benefit from deploying the same Flutter codebase to the web in addition to iOS and Android. We assess the trade-offs honestly and recommend only where it's genuinely beneficial.
App Store Submission & Optimisation
We handle the full App Store Connect and Google Play Console submission process, including screenshot generation, ASO (App Store Optimisation) metadata, and review compliance.
Our Process
How We Work
A transparent workflow so your team always knows what happens next and when feedback is needed.
01
Discovery & UX Mapping
Mobile UX is fundamentally different from web. We map touch interactions, navigation patterns, and offline behaviour before design begins.
02
UI Design in Figma (Mobile-First)
High-fidelity mobile screen designs with platform-specific component libraries (Material 3 for Android, Cupertino for iOS where appropriate).
03
Flutter Development in Sprints
Two-week sprints. TestFlight (iOS) and internal testing track (Android) builds with every sprint so you test on real devices.
04
API Integration & Data Layer
Clean separation between UI and data with the BLoC or Riverpod state management pattern. Testable, maintainable, and easy to extend.
05
App Store Submission & Launch
Full submission handling. We've navigated App Store review rejections — we know what triggers them and how to avoid them from the start.
