Starting with a well-defined product goal and awareness of device variety sets the stage for success. Outlining the MVP, choosing an architecture, and mapping key user flows early keeps the initial release focused and minimizes rework as the app evolves.

Once the foundation is set, focus shifts to UI consistency, speed, and compatibility across OS versions and screen sizes. Robust state management, careful networking, and dependable analytics and crash reporting simplify support and iteration after publishing on the Google Play Store.
