Mobile App Development agencies.
Mobile App Development is the build of iOS and Android applications, native (Swift or Kotlin) or cross-platform (React Native, Flutter, or Capacitor), covering discovery, UX and UI design, engineering, QA on real devices, App Store and Google Play submission, and post-launch maintenance. It sits next to web development but answers to a different set of platform rules.
