From prototype to App Store
We build native iOS apps with SwiftUI and cross-platform apps with Flutter. Both tracks go all the way through App Store submission and post-launch monitoring, not just code delivery.
Platform Decision
Native or cross-platform?
The right answer depends on your users, timeline, and product requirements, not which framework is trending.
| Factor | Native (SwiftUI) | Flutter |
|---|---|---|
| Performance | Native rendering, 60/120fps ProMotion | Near-native via Impeller renderer |
| Codebase | Separate per platform | Single codebase: iOS, Android, web |
| Platform APIs | Full, day-one access | Most APIs via packages; some gaps |
| Time to market | Longer (two codebases) | Faster, shared logic and UI |
| UI fidelity | Pixel-perfect platform UI | Custom UI, consistent cross-platform |
| Team model | Separate iOS/Android specialists | One cross-platform team |
| App Store compliance | Easiest review path | Fully compliant, more build config |
| Best for | iOS-first, perf-critical, deep OS integration | Multi-platform reach, speed, budget |
Case Studies
Apps in production
A subscription app that kept its rating
Consumer iOS app
A consumer health app with personalised plans, offline-first data, and subscription billing. Shipped with health-platform integration and enough test coverage that the next three feature releases went out without a regression.
- 40,000 downloads in the first month
- 4.8-star store rating
- Offline-first, usable without signal
- Three releases, zero regressions
One codebase, three countries
Cross-platform field operations app
Flutter app serving drivers, dispatchers, and customers from one codebase. Live route tracking, push notifications, Riverpod state management, and a custom Flutter Web dashboard for operations managers.
- 1,200+ field staff daily
- iOS, Android, and web from one codebase
- Live route tracking with real-time updates
- Three countries in production
Capabilities
What we integrate
From offline-first data sync to biometric auth and in-app purchase, these are the platform capabilities we integrate in real products, not just demo setups.

Architecture
Workflow
Design to post-launch
Every mobile project follows the same four phases. You get visibility at each stage and a working build in hand, not just status updates.
Design
Figma flows, component specs, and prototype review with your team before a line of code is written.
Build
Iterative two-week sprints with demo builds delivered to TestFlight or Firebase App Distribution.
Submission
We handle App Store and Play Store submission, screenshots, metadata, review responses, and binary preparation.
Post-launch
Crashlytics and Sentry dashboards configured for your team. We monitor the first two weeks and fix launch-day issues on priority.
Why FalcoFlow
What makes the work different
We have shipped to the App Store, not just simulated it
One consumer app reached 40,000 downloads at 4.8 stars; a field operations platform runs the working day for 1,200+ staff across three countries. Real production software with billing, offline sync, and live monitoring, not demos.
Architecture that survives the second year
Most mobile apps degrade because they were built without a clear state management strategy or module boundary plan. We use TCA or Riverpod from day one so the codebase stays coherent as features accumulate.
We write tests that catch production regressions
Unit tests for business logic, integration tests for data flows, and snapshot tests on critical screens. Tests are not a checkbox. They are what lets you ship the next release without holding your breath.
“We launched with 40,000 downloads in the first month. The test coverage meant the next three feature releases shipped without a single regression.”
