Service
Mobile Application Development Services
Hashorn builds mobile apps for iOS and Android using React Native for shared codebases and native Swift or Kotlin where the surface needs it. Every mobile engagement ships with device-lab coverage, crash reporting, and app-store release pipelines wired from day one.
Why teams hire us
What we solve
The recurring patterns that bring product teams to Hashorn.
Cross-platform apps that fall apart on real devices.
Mobile QA that only checks the happy path on simulators.
App-store release pipelines that block weekly delivery.
Crash rates that nobody monitors until customers complain.
Native APIs (camera, biometrics, deep links) bolted on poorly.
What you get
What we deliver
Concrete outcomes from every engagement, not slideware.
React Native apps with full TypeScript and offline support where needed.
Native Swift / Kotlin modules when the platform requires it.
Real-device QA coverage via BrowserStack App Live and physical hardware.
App-store release automation (Fastlane, EAS) wired into CI.
Crash reporting (Sentry, Crashlytics) and analytics from launch day.
