What does the OutSystems mobile debugger allow developers to do?

The OutSystems mobile debugger empowers developers to diagnose and fix issues in mobile applications during the development process. This is essential for ensuring that applications function correctly and efficiently before they are deployed to users. The debugger provides real-time insights into the app's performance, offers the ability to inspect variables, monitor network calls, and trace through logic, which significantly aids in identification and resolution of bugs.

This functionality contributes directly to improving the overall quality of the mobile application by allowing developers to catch and address issues early in the development cycle, thus reducing the likelihood of problems that could occur after deployment. It streamlines the workflow by providing a comprehensive toolset for managing and troubleshooting development challenges, which is crucial in a fast-paced development environment.

The other options focus on different aspects of the mobile application lifecycle that do not involve directly diagnosing or fixing issues during development. Publishing applications online pertains to making them accessible to users, designing user interfaces involves creating the look and feel of the app, and conducting user testing is about gathering feedback from actual users once the app is developed, rather than addressing development issues.
