Understanding Performance Metrics for Web and Mobile Apps

In today’s digital landscape, performance is critical for user retention and engagement. Technical founders must understand the key performance metrics that directly impact the experience of web and mobile applications.

1. Key Metrics to Monitor

Focusing on crucial metrics allows you to pinpoint the areas needing improvement. Major performance indicators include:

  • Page Load Time
  • Time to First Byte (TTFB)
  • First Contentful Paint (FCP)
  • Interactions per Second

2. User Experience and Performance

Performance issues can lead to user frustration, causing users to abandon your app. Conducting regular performance assessments ensures that your app can handle user demands.

3. Conclusion

As a technical founder, having a grasp of these metrics sets a foundation for optimizing your applications. Use tools like Google Lighthouse and WebPageTest to regularly analyze performance.
