Flutter app development company

Flutter and iOS app development for products that need to perform

Cross-platform Flutter and native Swift apps, engineered for store ratings, real-time features, and long-term maintainability.

Book a strategy call Send a project brief

A Flutter app development company builds iOS and Android apps from a single Dart codebase, which typically shortens delivery and keeps both platforms in sync. For features that need deep platform access, such as VPN tunnels, Bluetooth accessories, or background location, we write native Swift or Kotlin modules. Our founder has led development on consumer apps in mobility, food delivery, healthcare, and communications, including a Dubai ride-hailing app whose store rating rose from 3.2 to 4.6.

Outcomes

What changes for your business

Ratings that support growth

Crash-free sessions, fast start-up, and polished flows are engineering outcomes. We measure them and treat regressions as bugs.

One team, both platforms

Flutter lets one senior team ship iOS and Android together, so features do not drift apart.

Real-time that feels instant

Live tracking, chat, and calling built on proven real-time infrastructure, tested on poor networks.

What we build

Typical mobile apps (flutter / ios) projects

Consumer apps

Mobility, delivery, booking, and marketplace apps with payments, maps, and live tracking.

Healthcare and regulated apps

Patient and clinician apps with secure data handling, audit logs, and accessibility.

Native iOS (Swift)

VPN (NetworkExtension), CoreBluetooth, HealthKit, and other capabilities that need native code.

App rescue and modernization

Stabilizing existing apps: crash reduction, performance work, test coverage, and migration to current Flutter or Swift.

Approach

How we deliver it

This sits inside our standard delivery process: weekly demos, a shared board, and monthly reporting.

Technology

Product and architecture workshop: user flows, data model, and release plan.
Design system and clickable prototype before feature development.
Two-week sprints with a TestFlight / internal testing build at every demo.
Automated tests, crash monitoring, and performance budgets from sprint one.
Store submission, staged rollout, and post-launch monitoring.

Flutter vs. native (Swift / Kotlin)

	Flutter	Native
Codebases	One for iOS and Android	One per platform
Delivery speed	Typically faster for both platforms together	Slower when building two apps
Deep OS features	Via native modules	Direct access
Best for	Most consumer and business apps	VPN, heavy Bluetooth, platform-specific UX

Mobile apps (Flutter / iOS): frequently asked questions

Should we build with Flutter or native iOS and Android?

For most products, Flutter is the faster path to a high-quality app on both platforms. We recommend native Swift or Kotlin when the core of the product depends on deep OS features, such as VPN tunnels or complex Bluetooth accessories.

Can you take over an existing app?

Yes. We start with a two-week technical audit covering code quality, crash data, architecture, and release process, then agree a stabilization plan before adding features.

Do you handle App Store and Google Play submission?

Yes, including store listings, privacy declarations, review responses, and staged rollouts.

Who owns the source code?

You do. IP transfers to you under our agreement and the code lives in your repositories from day one.
