With millions of apps competing for attention on platforms like Google Play and the App Store, ensuring high performance and user retention has become crucial, as 88% of users abandon apps due to bugs and glitches. To address this, various load testing tools are available to help mobile developers maintain app quality under stress. WebLOAD, primarily for web platforms, integrates with Perfecto Mobile for realistic mobile testing, while LoadUI Pro enables rapid API performance testing. Apica LoadTest ensures scalability for apps and IoT by identifying bottlenecks before they impact users. CloudTest offers stress testing for handling sudden traffic spikes, and LoadRunner provides continuous testing with real-time performance monitoring. WAPT is user-friendly for those with limited QA experience, offering both standard and Pro versions, whereas NeoLoad caters to mobile and IoT testing with options for real user simulation across different network conditions and devices. Pricing for these tools varies, with some offering free trials or versions and others requiring subscriptions based on usage or features.
