Why Mobile Apps

Your users are on mobile. Your app should be remarkable.

The average smartphone user spends 4+ hours a day in apps. A mediocre mobile experience doesn't just lose customers — it actively damages your brand. The companies winning on mobile today started investing in native-quality experiences 12–18 months ago.

We build every layer — UX, engineering, backend, and store submission. Every feature is purposeful, every screen is tested, and every app we ship comes with full source ownership and documentation so your team can run it independently.

What We Do

Six disciplines. One seamless app experience.

Great mobile apps don't happen by accident — they're built on a foundation of thoughtful design, clean engineering, and relentless performance optimisation across every layer of the stack.

Cross-Platform Development

One codebase, two stores. We build with React Native and Flutter to ship iOS and Android apps simultaneously — without sacrificing native performance, animations, or platform conventions.

React NativeFlutterExpo iOSAndroid

Native iOS & Android

When performance and platform depth matter most, we go fully native. Swift for iOS and Kotlin for Android deliver 60fps animations, instant startup, and access to every device capability — camera, NFC, biometrics, and beyond.

SwiftSwiftUIKotlin Jetpack ComposeCoreML

Mobile UI/UX Design

We design screen-by-screen in Figma following Apple HIG and Material Design 3 guidelines — then validate every flow with usability testing before a single line of code is written. Beautiful and usable, always both.

FigmaPrototypingHIG Material 3Usability Testing

Backend & API Architecture

Mobile apps are only as strong as their backends. We build scalable REST and GraphQL APIs, real-time WebSocket services, push notification infrastructure, and offline-first sync using Firebase, Supabase, or custom Node.js services.

FirebaseSupabaseGraphQL Node.jsWebSockets

App Store Optimisation

Visibility in the App Store and Google Play is earned. We optimise titles, subtitles, keywords, screenshots, and preview videos — and back it up with A/B testing through Apple's built-in product page optimisation tool.

Maintenance & Growth

Post-launch is where most apps lose momentum. Our ongoing retainer covers OS compatibility updates, crash monitoring via Sentry, feature additions, user feedback loops, and monthly analytics reviews tied to retention and revenue metrics.

Engineering Deep Dive

We find what makes apps fail — and build yours to avoid every one

Most failed apps share the same root causes: slow startup, poor offline handling, excessive battery drain, broken push notifications, and app store rejections that could have been avoided. We've seen every failure mode and our process eliminates them systematically.

Our pre-development architecture review covers security, scalability, and platform compliance — so the code we write doesn't need to be rewritten six months later.

  • Performance Architecture — State management, rendering optimisation, and lazy loading strategies for sub-2-second cold start on mid-range Android devices.
  • Offline-First Design — SQLite and MMKV caching, background sync, and conflict resolution so your app works seamlessly without connectivity.
  • Security & Compliance — Certificate pinning, secure storage, biometric auth, GDPR data handling, and App Store Review guideline compliance from day one.
  • Push & Engagement — FCM/APNs architecture, deep-linking, rich notifications, and in-app messaging designed around retention outcomes.
  • CI/CD Pipeline — Automated builds, unit and integration tests, Fastlane deployment, and staged rollouts to both stores without manual intervention.

What We Measure

Every metric that actually matters

App Performance

Startup time, frame rate, memory usage, and ANR rate tracked in production via Firebase Performance Monitoring.

Daily Active Users

DAU, MAU, and DAU/MAU ratio — the engagement health signal that predicts long-term app survival and growth.

Retention Curves

Day 1, Day 7, Day 30 cohort retention tracked in Mixpanel — identifying exactly where users drop off and why.

Revenue Metrics

MRR, ARPU, LTV, and in-app purchase conversion rates attributed to acquisition channel and user segment.

Crash Rate

Real-time crash and ANR monitoring via Sentry and Firebase Crashlytics — with alert thresholds and automated rollback triggers.

Push CTR

Notification open rates, opt-out trends, and campaign attribution — so every push message improves engagement, not uninstall rate.

Store Rating

App Store and Play Store rating trends, review sentiment analysis, and competitive benchmark against category averages.

Update Adoption

Version distribution and forced-update threshold monitoring — ensuring your user base stays on supported, compliant builds.

App Analytics

Your app's heartbeat, fully visible

We build a unified dashboard connecting Firebase, Mixpanel, Sentry, and your revenue platform — so you can see user behaviour, performance, and revenue in one place.
