Go Beyond Functionality—Ensure Performance, Security & Usability at Scale
At Squash Apps, we know that great software isn’t just about what it does—it’s also about how it behaves under pressure, across environments, and in the hands of users. Our Non-Functional Testing services validate the critical quality attributes that determine real-world success, from high speed and good scalability to security.
Whether you're launching a new web app, mobile solution, or enterprise system, we help you uncover hidden risks and optimize user experience—before they impact your users or your brand.
