  • Prototyping: This is an important step in app building, which includes creating interactive and clickable models of the app that assume its functionality. With prototyping, you can easily test the user flow by allowing users to communicate with your app’s design. In this phase, you can detect issues in UX and verify your design. Before you start development, make sure that your app's navigation is intuitive.

Both wireframes and prototyping provide a clear roadmap for app building, bringing developers and designers under one roof to work on the same vision.

Create a plan for functionality. Define key features that can meet the needs of your business and target users. Moreover, follow the design guidelines according to the platform you have chosen.

You can refer to various tools for app design. Choosing the right tool while coding can streamline the app development process. Sketch or Figma are ideal for UI/UX design. If you want to build interactive prototypes, InVision and Marvel will be the perfect choices. You can use Adobe XD tools for extensive app design and prototyping.

Opting for the Right Technology Stack:

Opting for the right technology stack is important while coding, as it affects the speed, performance, and scalability of your app. Hence, choose it wisely. If you go with Python or Django, it will streamline app development and ensure scalability. These stacks are beneficial to apps that deal with high volumes.

Factors to consider while choosing a technology stack:

  • Choose your platform for your app. Pick iOS and Android or both.
  • Define the app type: whether you want to build a simple app or a feature-rich one.
