Overview

Mobile Apps That Perform Like Native

The era of "we'll build a mobile app eventually" is over. Customers expect mobile-first experiences, and brands that deliver them see higher retention, more frequent purchases, and deeper brand engagement.

We build Flutter applications that deliver native iOS and Android performance from a single codebase — without the compromises that have historically plagued cross-platform development.

Why Flutter

Flutter is Contra Collective's default choice for cross-platform mobile development. The reasons:

Performance: Flutter compiles to native ARM code and uses its own high-performance rendering engine (Impeller). UI feels indistinguishable from native because it IS running native code — not JavaScript interpreted through a bridge.

Single codebase: One codebase runs on iOS, Android, and (optionally) web and desktop. Feature development, bug fixes, and updates happen once and ship to all platforms simultaneously.

Dart language: Dart is a modern, strongly-typed language with excellent tooling. Developers familiar with JavaScript or TypeScript pick it up quickly.

Ecosystem maturity: Flutter has a rich package ecosystem for common needs — payments, analytics, push notifications, authentication, and device APIs are all well-supported.

Commerce Mobile Apps

We specialize in mobile applications for e-commerce brands. A native commerce app delivers capabilities no mobile web experience can match:

  • Push notifications for order status, promotions, and back-in-stock alerts — with 3-5x higher open rates than email
  • Biometric authentication for seamless one-tap checkout
  • Offline browsing so customers can browse your catalog without a connection
  • Deep linking from email, social, and paid campaigns directly to product pages
  • App Clips (iOS) and Instant Apps (Android) for frictionless trial experiences

We connect Flutter apps to Shopify via the Storefront API for product, cart, and checkout data — maintaining Shopify's secure checkout while delivering a fully native experience.

The App Launch Process

We manage the full lifecycle:

  1. Architecture and design: Wireframes, user flows, and component design
  2. Development: Incremental builds with weekly demos
  3. QA: Automated tests, device compatibility testing, performance benchmarking
  4. App Store submission: Apple and Google review management
  5. Launch monitoring: Crash reporting, performance metrics, user feedback

Post-launch, we provide a maintenance plan covering OS updates, API changes, and feature iterations.

FAQ

Common Questions

Everything you need to know before starting a project with us.

Flutter compiles to native ARM code and uses its own rendering engine — consistently higher performance than React Native's JavaScript bridge. It's also a single language (Dart) across all platforms.

Apple review typically takes 1-3 days for initial submissions, up to 7 days for new apps. We submit early in the process to avoid launch delays.
