The best ideas for new features and other improvements to existing software apps often come from enthusiastic users. Implementing new features creates opportunities for refactoring mobile apps. After several years using the MobileTogether Solar Data Tracking app to monitor the performance of a rooftop solar system, my friend Casey had a suggestion.

The app displayed one page of charts and tables to report production by month over a year and another page to report daily production for the last 30 days. Navigation buttons on each page enabled easy switching between views. Casey’s suggestion was to revise the app to place all the charts and tables on a single page. Over time mobile users have become accustomed to mobile apps that present data in long pages that scroll with a quick one-finger swipe motion. A one-page app would feel smooth and more up-to-date.
