NAPA Auto Parts is one of the largest automotive parts retailers in the United States. Their NAPA “Know How” app was experiencing problems due to updates in the iOS and Android operating systems. These issues had a negative impact on the user experience and were reflected in the NAPA app’s store rating. We partnered with NAPA to address the issues and to refresh the mobile user experience. Our measurable goal for the project was to see an improvement in the app store ratings for both the iOS and Android app.
