App Development

01Requirement Consultation

At the start of our collaboration, we conduct in-depth interviews to understand your business model, core functionalities, and budget direction, breaking down the requirements into executable development items. Once the project is confirmed, the project manager immediately assembles a team and initiates a complete planning process, ensuring that subsequent progress is clear and controllable.

Requirement Consultation
02UI/UX Visual Design Planning

Upon entering the UI/UX design phase, we focus on user experience to create interfaces and operational flows with high usability. The design will be finalized after multiple rounds of discussion and adjustment, ensuring that the brand visuals, usage logic, and real-world scenarios are consistent and logical.

UI/UX Visual Design Planning
03Programming, Automated Deployment, and Testing

The entire programming development process adheres to our internal standard procedures and ISO 27001 requirements. nThis is complemented by automated testing, version control, managerial-level code review, and multiple security checks, ensuring that the product maintains long-term stability in terms of performance, quality, and information security.

Programming, Automated Deployment, and Testing
04Launch and Deployment

Upon completion of development, we assist with launching the app on both platforms. Our familiarity with the App Store and Google Play review guidelines effectively reduces delays caused by inconsistent understanding of policies. We also provide server architecture recommendations and deployment services, ensuring the entire system is in its optimal state before the official launch.

Launch and Deployment
05Warranty and Maintenance

A warranty period will be clearly stipulated in the contract for all projects, with the duration depending on the development cost and functional complexity. During the warranty period, we provide free corrections for any defects inherent to the system itself. Should continuous maintenance be required after the warranty expires, we can offer stable long-term operation and maintenance services. The cost will be approximately 10% to 18% of the original project amount and will be adjusted based on the system scale and the personnel required for subsequent work.
