Starting with a clear product goal and awareness of device variability sets the course for app development. Defining the minimum viable product, choosing an architectural approach, and outlining essential user flows early on helps keep the initial release focused and minimizes rework as the app evolves.

Once the foundation is established, focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful network usage, and dependable analytics and crash reporting simplify support and iteration after the app goes live on the Play Store.
