Mobile apps play a pivotal role in today’s digital world, linking consumers, businesses, and technology. The widespread usage of smartphones and mobile apps provides users with access to services and information around the clock. They promote a mobile-first culture by enabling users to communicate, shop, learn, and stay connected from any location. Therefore, performance testing is essential to ensure that mobile applications continue to be responsive, stable, and effective in real-world usage. Performance testing is a very important topic now than ever to ensure scalability, responsiveness, and dependability across different devices and network environments, given the explosive growth of mobile applications. Primary focused on web load testing with limited exploration of mobile-specific performance metrics. This paper focuses on the results and efficacy of mobile application performance testing tools. The evaluation included open-source and commercial tools like Apache Jmeter, BrowserStack, Android Studio, Firebase, and Apptim. The experiment has been designed to analyse important performance metrics under various load scenarios, including response time, throughput, CPU and memory utilisation, and error rates. The market is filled with a wide variety of performance testing tools. Every instrument has benefits and drawbacks, therefore it might be challenging to select the best one for the job. According to this experimental investigation, the tool selection must align with the mobile application testing goals and performance indicators.
