How do you measure and improve mobile app design quality using quantitative metrics?

1 What is Quantitative Feedback?

Quantitative feedback is any data that can be measured, counted, or expressed in numbers. For example, metrics such as downloads, ratings, retention, revenue, or user behavior. Quantitative feedback can help you track the performance of your app, identify trends, and test hypotheses. You can use tools such as analytics, surveys, or A/B testing to collect and analyze quantitative feedback.

2 What is Qualitative Feedback?

Qualitative feedback is any data that can be observed, described, or interpreted in words. For example, feedback such as user reviews, comments, interviews, or user testing. Qualitative feedback can help you understand the needs, preferences, and emotions of your users, as well as the strengths and weaknesses of your app design. You can use methods such as user research, focus groups, or usability testing to collect and analyze qualitative feedback.

3 How to Balance Quantitative and Qualitative Feedback?

Quantitative and qualitative feedback should be used in tandem to inform your app design decisions. To balance both types of feedback, start with qualitative feedback to explore the problem space, generate ideas, and validate assumptions. Then use quantitative feedback to measure the impact, evaluate the results, and optimize the solution. Combining quantitative and qualitative feedback can help triangulate the data, find patterns, and explain the why behind the what. Lastly, iterate and refine your app design based on both feedback types, and keep testing and learning from your users.

4 How to Collect Quantitative Feedback?

To collect quantitative feedback for your app design, there are many tools and methods available. Analytics platforms like Google Analytics, Firebase, or Mixpanel can track and measure user behavior, engagement, and retention. Surveys platforms such as SurveyMonkey, Typeform, or Google Forms can ask users questions about their satisfaction and expectations. A/B testing platforms like Optimizely, Firebase Remote Config, or Google Optimize can compare different versions of your app design to determine which one performs better. Metrics such as sessions, events, conversions, funnels, click-through rate, conversion rate, or retention rate can be used to quantify user feedback and evaluate the effectiveness of your design variations.

5 How to Collect Qualitative Feedback?

Collecting qualitative feedback for your app design can be done in a variety of ways. User reviews, interviews, and user testing are some of the most effective methods. For example, user review platforms such as App Store, Google Play, and Product Hunt can provide useful insights and feedback from user reviews and comments. Interviews platforms such as Zoom and Skype allow you to talk to your users directly and ask open-ended questions about their experience. Lastly, user testing platforms such as UserTesting and Lookback can observe how users use your app in real or simulated scenarios. Through these methods, you can collect feedback on actions, reactions, or thoughts.
