Luciq's Frustration-Free Sessions provides a comprehensive metric for assessing the user experience of mobile apps by evaluating all aspects of app performance, including crash-free sessions, app hangs, launch and load times, and network performance. This metric categorizes user sessions into crashing, frustrating, tolerable, or satisfying, based on the impact of various performance metrics, with ANRs and app hangs having the highest impact. The overall Frustration-Free Sessions score is calculated by combining these weighted categories, allowing app developers to pinpoint areas needing improvement. Users can customize the calculation by adjusting metric impacts, targets, and key performance indicators to better reflect their app's context. Additionally, an automatically prioritized issues list helps developers focus on the most impactful issues, which can be integrated into project management tools like Jira for streamlined resolution.
