The first and basic step is to devise a product requirement document that assists our team to sort and find appropriate solutions to the users’ needs. It provides a clear view and detailed guidelines on how to proceed with the application development from the beginning to its end. It contains:

• Business requirements
• Functional & non-functional requirements
• Technical Specifications
• User Journeys
• UI essentials
• Maintenance and upgrade specifications.

A logical and well-structured mobile app is constructed with the help of sharp architecture. It is the backbone of any mobile application and there are several architecture patterns used for implementation. We follow as below :

• Deciding on the device types that the app supports.
• Designing the app for the best user experience even in worst-case scenarios.
• Analyzing apt navigation methods for the app
• Maintaining consistent flow in the architecture

A visual structure of the app is enabled through wireframing and highlighting the UX factor. Designers provide multiple solutions as to how ideas and proposed features combine into a functional mobile app. It includes screen elements, content hierarchy, object categories, intended actions, available features, and functions.

In order to create a user-friendly experience, we need to focus on agile and user-centric design that stimulates repeated engagement. While designing mobile apps some of the requisites considered are:

• Maximise mobile app usability
Simplify navigation and make it visible Avoid visual clutter by minimizing content Minimize user input by analyzing the requirements Maintain consistency in design

Testing is mandatory for best quality products and on-time delivery. It helps in bug fixing and saving time during actual development. Automated testing enables 24*7 test execution thereby reducing the testing time of the whole app as well as new features. In order to evaluate app performance, cloud-based testing platforms are used on thousands of real devices to obtain a global perspective.

The criteria followed by our team before an app launch are as below.

• Abide by the publishing process guidelines in the app store.
• Perform according to the policies and agreements in the app store
• Inspect the app size and compatibility on targeted platforms
• Optimise the app
• Conduct content rating for the app's maturity level
• Designate locations for app distribution
