Case Study: Acasa achieves fewer crashes and higher NPS with Global App Testing

Reducing crash rates and improving NPS

Acasa, a London-based app that helps renters manage and split household bills, was struggling with an inconsistent, manual approach to QA. As the team focused on building the product, they lacked dedicated testers and relied on staff, beta users, and bug reports from customers, which created tension, slowed releases, and made it difficult to confidently launch new features. To address this, Acasa turned to Global App Testing for crowdsourced QA support.

Global App Testing began with exploratory testing to uncover edge cases and compatibility issues across devices and operating systems, then helped Acasa build regression test cases to protect stable areas of the app. The partnership produced detailed bug reports and gave the team a clearer QA process, reducing internal pressure and allowing developers to focus on building. As a result, Acasa reduced its crash rate and improved its Net Promoter Score, which has stayed up.
