Code Neptune is a full-service mobile app development agency in India delivering custom-built mobile applications for businesses of all sizes.
We build Android apps people love to use. Our app makers own the entire journey, applying Google Material Design best practices, running multi-device performance tests, and configuring Play Store listings for maximum visibility.
iOS apps are engineered using Apple’s latest frameworks to deliver the premium experience iPhone users expect. We also manage TestFlight builds, App Store compliance, and launch approval so your iOS app meets Apple’s design standards.
We use Flutter and React Native to build apps that look and perform like native apps at half the price. Our app developers write clean, maintainable code that supports future upgrades and publish both builds simultaneously.
Beyond looking good on screens, we also conduct user flow mapping, micro-interaction design, thumb-zone ergonomics and mobile-specific usability testing for the mobile apps we build. We ensure every screen is built for speed, clarity, and conversion.
Already have an old app? We upgrade outdated apps by rebuilding legacy codebases, redesigning UI, integrating new-age features like biometric login, push notifications and live chat. Whether you need a simple UI refresh or a complete rebuild, our custom mobile app development service has you covered.
We convert your website into a full-featured mobile app by replicating your core functionality, optimizing API responses, and creating app-specific navigation. Your users get a faster, smoother experience built specifically for mobile from your existing website.
Technology Stack
Uniting the best native, cross-platform, backend, and cloud technologies to bring your mobile app to life. Our app developers select the ideal stack for your app’s functionality, goals, and user needs.
Our process involves a team of experts working in parallel across each phase of the project. This collaborative approach ensures that every aspect is handled by a specialist, resulting in high-quality deliverables on time.
Creating a detailed feature plan, user flows, and technical roadmap based on your goals and audience.
Developing wireframes, UI designs, and clickable prototypes to validate the user experience early.
Building clean, scalable code with secure APIs, fast performance, and reliable backend architecture.
Testing your app across devices for functionality, speed, security, and multi-OS compatibility.
Preparing store-ready builds and managing the complete Google Play and App Store submission process.
Providing 3 months of free monitoring, bug fixes, updates, and performance optimizations after launch.
