The mobile app industry has witnessed significant growth over the past decade, with user expectations for performance increasing as a result of their reliance on mobile apps. Research suggests that human-computer interaction studies have shown that users are most comfortable and productive when computer response times are less than 2 seconds, and waiting more than this threshold can lead to increased stress levels and decreased conversions. Mobile app performance is crucial for success, with even small improvements in loading time resulting in significant increases in conversion rates and revenue. To achieve optimal performance, it's essential to use Apdex scores, conduct extensive testing, collect user feedback, monitor and alert on performance issues, enhance stability, and balance release frequency with new features and performance improvements. Collaboration among teams is also vital for optimizing workflow efficiency.
