Starting with a clear product goal and awareness of device diversity lays the groundwork for success. Defining the MVP, choosing an architecture, and mapping core user flows early keeps the initial release focused and reduces rework as the app evolves.

Once the foundation is set, focus shifts to UI consistency, performance, and compatibility across different OS versions and screen sizes. Robust state management, careful networking, and dependable analytics/crash reporting simplify maintenance and iteration after the Google Play launch.
