We build and publish apps people love to use.
JAPROX LTD designs, develops, launches and operates mobile apps and web apps for iOS, Android and the browser. We publish our own products and help businesses turn ideas into polished, reliable software.

Native and cross-platform apps for iOS and Android built with Swift, Kotlin, Flutter and React Native.
Web app development
Fast, secure and responsive web applications, progressive web apps (PWAs) and admin dashboards.
App publishing
We publish and manage apps on the Apple App Store and Google Play, including listings, compliance and releases.
UI/UX design
User research, wireframes, prototypes and polished interfaces that are accessible and easy to use.
Cloud & backend
Scalable APIs, databases, authentication, push notifications and analytics on Firebase and Google Cloud.
Maintenance & growth
OS updates, bug fixes, performance tuning, monitoring and data-driven feature improvements.
Developer and publisher, under one roof
We don't only write code. We ship and run real products, so we understand what it takes to get an app approved, discovered and kept healthy after launch.
- App Store and Google Play submission, review and policy compliance
- Privacy-first engineering aligned with UK GDPR and EU GDPR
- Clear, fixed-scope proposals and transparent communication
- You own your code and intellectual property on client projects
- Ongoing support plans after launch
