The stability will depend. I was running a test on my mobile and I got a call and I had to pick up and then the test was running, but when I connected again the mobile and stopped the test run, the application crashed.

I reopened the ticket because our manager was in contact with someone at SmartBear and we cannot send our application. Sometimes when we expand something in the collection view and we want to tap in the test, the application is forced closed and there's an error occurred and no details.

The usage depends on the project that I'm working on. Until the beginning of this year, I used it weekly, like every day when I was at working hours. 

We've had some problems with crashes, but that was when we were using the previous version. Everything has been running smooth on the latest version.
