Cross-platform App Development Process


Requirement Analysis

We understand your target audience, the problem your native apps aim to solve, and the features to include. Overall, we validate the feasibility of your idea and provide guidance to proceed.


Planning & Design

The business analysis team prepares the wireframes or mockups to visualize the user interface. The UI/UX team designs the interfaces as per the wireframe prepared considering the guidelines.



Using a cross-platform framework like Flutter and React Native, our experienced cross-platform app developers create the app to work across multiple platforms (iOS, Android, and web) from a single codebase.



The app undergoes rigorous testing to identify and fix bugs, and performance issues. This ensures that the app works across all specific platforms and meets the quality standard of your cross-platform app.



Once the app is tested and approved, your app is deployed. The app is submitted to various app stores, such as Apple’s App Store and Google Play, and may also be deployed on a web server for web access.


Maintenance & Updates

Post-launch, the app requires attentive maintenance to fix any emerging bugs. We periodically update your app with features based on valuable user feedback and ever-changing market needs.
