Premium mobile products,engineered to scale.

Cross-platform mobile app development on Flutter and Dart, with native Kotlin and Swift used where the platform requires it. We design, build, and ship iOS and Android apps from a single codebase, then handle App Store and Play Store submission, staged rollouts, observability, and post-launch iteration against real user feedback.

iOS and Android apps that feel native, ship fast, and survive their second week in users' hands. Built on a Flutter and Dart core, with Kotlin and Swift dropped in the moment the platform actually demands it.

What we deliver

Mobile experiences that earn their place.

Three principles every mobile build sits on top of: native feel with no platform compromise; one team that ships every platform from a single Flutter and Dart core; and production engineering in place from the first commit — observability, crash reporting, and release pipelines included rather than bolted on later.

Three things define every mobile product we ship. The framework is a means to that end, not the headline.

01

Native feel, no compromise

Animations stay 60fps, gestures match each platform's conventions, and nothing about the UI tells the user this isn't a native app.

02

One team, every platform

iOS, Android, and the web from a single Dart codebase. The same engineers cover every screen — fewer handoffs, faster iteration.

03

Production from day one

CI/CD, observability, crash reporting, and feature flags wired in from the first build. Apps designed to survive their second week in the wild.

The stack

The toolkit we reach for in production.

The mobile stack: Flutter and Dart as the cross-platform core; native Kotlin and Swift where the platform requires it; Firebase and Cloud Functions for backend with PostgreSQL when needed; GitHub Actions, Fastlane, and Codemagic for CI/CD; App Store Connect and Google Play Console for distribution; Sentry for error monitoring and Mixpanel for analytics.

Six categories, picked because they each survive the move from prototype to scale without us having to rip them out and start over.

App framework

The core layer every mobile build sits on top of.

  • Flutter
  • Dart

Native platform

Dropped in the moment iOS or Android actually needs it.

  • Kotlin
  • Swift
  • Platform Channels

Backend

Auth, data, real-time, and the server-side glue.

  • Firebase
  • Node.js
  • PostgreSQL
  • Cloud Functions

DevOps & CI/CD

Shipping is a workflow, not a hand-off.

  • GitHub Actions
  • Fastlane
  • Codemagic
  • Sentry

Distribution

From staging build to live store listing.

  • App Store
  • Google Play
  • TestFlight
  • Firebase App Distribution

Product integrations

The parts users feel even when they don't see them.

  • Stripe
  • OneSignal
  • Mixpanel
  • RevenueCat

How we ship

From first call to App Store in five phases.

A mobile delivery pipeline that goes from discovery and scope through product design, build sprints in Flutter, QA on real devices, App Store and Play Store submission, and post-launch iteration. A typical store-ready mobile MVP reaches production in six to ten weeks, with staged rollouts and observability wired in before launch day.

The same pipeline we run on every serious build. Each phase has its own deliverables, sign-offs, and the freedom to revisit the last one when reality requires it.

  1. Planning & discovery

    We sit with the problem long enough to actually understand it. Mapping users, constraints, success metrics, and what the smallest valuable v1 looks like.

  2. Design & prototyping

    Wireframes, interactive prototypes, and the design system the app will be built on. Decisions get tested before they get coded.

  3. Development

    Agile sprints with weekly check-ins. We share progress builds early and often, so feedback loops happen at the speed of the build.

  4. Testing & QA

    Automated tests, manual regression on real devices, edge-case handling, and performance benchmarks. The unglamorous work that keeps day-two apps alive.

  5. Deployment

    App Store and Play Store submission, staged rollouts, observability wired in. Plus post-launch support against real user feedback once it's live.

Where we ship

Mobile products across the industries where experience moves the business.

Mobile products shipped across six categories: healthcare and telehealth, fintech and payments, retail and e-commerce, education and EdTech, social and community, and wellness and lifestyle. Each app is shaped to the constraints of its domain — sensitive data handling, payment compliance, offline behaviour, animation budgets — rather than dropped onto a generic template.

Healthcare & telehealth

Patient apps, clinician tooling, secure data flows. Built for sensitive workflows where reliability is the feature.

Fintech & payments

Banking apps, wallets, and trading platforms. Secure by default, with biometrics and compliance baked in.

Retail & e-commerce

Shopping apps, loyalty programs, POS extensions. Optimised checkout flows that convert and stay snappy at scale.

Education & EdTech

Learning apps, course platforms, assessment tools. Interfaces that work as well on a phone as on a classroom screen.

Social & community

Messaging, communities, content platforms. Real-time updates, media pipelines, and the moderation tooling teams actually use.

Wellness & lifestyle

Workout trackers, habit apps, on-demand classes. Animation-heavy interfaces that feel premium on every device.

Built & shipped

Real mobile products, live in production.

Two recent mobile builds shipped end-to-end. From product thinking and design through to App Store submission and post-launch support.

FAQ

Frequently asked questions

  • How much does it cost to build a mobile app?
    A cross-platform Flutter MVP typically ranges from $5,000 to $30,000 depending on scope. One Dart codebase ships to both iOS and Android, which is generally more cost-effective than building two native apps separately. We scope requirements first, then provide a fixed estimate.
  • How long does it take to build a mobile MVP?
    Most mobile MVPs reach a store-ready production build in 6 to 10 weeks.
  • Is Flutter suitable for production apps?
    Yes. Flutter ships native-performance iOS and Android apps from a single Dart codebase, with native Kotlin or Swift dropped in where the platform requires it.
  • Can you take over an existing Flutter codebase?
    Yes. We audit, rescue, and extend existing Flutter and Dart projects, including feature delivery and performance work on production apps.
  • Do you work with US-based startups?
    Yes. We have delivered products for US-based clients, and work with founders across the US, UK, UAE, and Singapore with working-hours overlap and async delivery.
