The manually automated app development process we follow blends human intervention with creativity and automation to accelerate the conventional process of app development by injecting efficiency and effectiveness.

From the initial discovery meeting to post-deployment support, every aspect of the app development process at Keach Digital Agency has been fine-tuned to ensure performance and adaptability.

Discover & Strategize

In the initial phase, our custom app developers understand your objectives, target audience, and app requirements.

This leads to the formulation of a strategic development plan that aligns with your objectives and sets the foundation for the app development process.

Design & User Experience

This phase focuses on leveraging our UI/UX expertise to create an intuitive and engaging user interface, design, experience, and visuals of your application.

Our UI/UX developers create minimal yet impactful layouts and navigational elements. We then test the experience for seamlessness and predictability.

App Development & Testing

Our custom app development services finally reach completion by bringing the app design to life by integrating robust functionality created through a rigorous process of ideating and testing technologies such as programming languages and more.

The app undergoes comprehensive quality testing and assurance to ensure it is bug-free, user-friendly, and ready for launch.

Development & Post-Launch Maintenance 

Once the app passes the Q/A phase and is tested for performance, functionality, response, and other critical metrics, we deploy it to the app stores, which include Android and iOS.

But the job doesn’t end there. We provide ongoing support and updates to ensure your app stays current and continues to meet user needs. (this depends on whether you need post-deployment maintenance or not)
