Mobile Apps Built for Retention, Revenue & Real Users
Custom iOS, Android & cross-platform apps built with React Native, Flutter, and native SDKs — fast cold starts, offline-first architecture, and App Store-ready from day one.
What We Build
App Development Services
From MVP to enterprise — every app is scoped clearly, built cleanly, and shipped to both stores on time.
React Native Apps
Cross-platform iOS & Android apps from a single codebase. Native performance, deep device API access, OTA updates, and App Store / Play Store deployment.
Flutter Development
Pixel-perfect, 60fps cross-platform apps with Flutter. Ideal for brands that need a consistent, custom UI across mobile, web, and desktop simultaneously.
Native iOS Development
SwiftUI and UIKit apps engineered for Apple's ecosystem — ARKit, CoreML, HealthKit, and deep system integrations that cross-platform tools can't match.
Native Android Development
Jetpack Compose & Kotlin apps optimised for the full Android device spectrum — offline-first architecture, background sync, and Play Store compliance built in.
App Backend & APIs
Scalable mobile backends with push notifications, real-time sync, media storage, and auth — REST or GraphQL, Firebase or custom Node.js infrastructure.
App Store Optimisation & Launch
App Store & Play Store listing optimisation, screenshot design, metadata strategy, review management, and launch-day monitoring for maximum visibility.
Our Stack
Technology We Master
Battle-tested tools chosen for performance, App Store compliance, and long-term maintainability.

How We Work
Our App Dev Process
Discovery & UX Scoping
User flows, feature prioritisation, platform strategy, and a fixed-price or sprint-based proposal aligned to your roadmap.
Design & Prototype
Figma screens with native component libraries, interactive prototype on real devices before any code is written.
Build, Test & Review
Biweekly TestFlight / Play Console builds. Unit, widget, and integration tests. You review on your device, we iterate.
Launch & Post-Launch
Store submission, review management, crash monitoring, analytics setup, and a structured handover with full documentation.
Why StratixFlow
App Engineers Who Think Like Product Owners.
We don't just write screens — we ask why the feature exists, whether the UX will actually retain users, and whether the architecture will scale to your next million downloads. You get engineers who care about your product, not just the ticket.
Performance-Obsessed Builds
We profile every screen with Flipper and Instruments. Jank-free scrolling, fast cold starts, and lean bundle sizes are baseline, not bonus.
Offline-First Architecture
Mobile users lose signal. We build apps that keep working — local-first data, background sync queues, and graceful conflict resolution.
Security & Compliance
Keychain / Keystore credential storage, certificate pinning, biometric auth, and GDPR-ready data handling — App Store and enterprise policy compliant.
Deep Platform Integration
Widgets, Shortcuts, Live Activities, Siri, Google Assistant, NFC, Bluetooth, camera pipelines — we unlock the hardware, not just the screen.
Full Source & IP Ownership
On delivery you receive 100% of the source code, certificates, provisioning profiles, and store credentials — nothing held back.
Iterative Sprints & Fast Delivery
Testflight & Firebase App Distribution builds every two weeks. Crash analytics, feedback loops, and production monitoring from day one.
