DevMate's UI makes it very user friendly, especially when you have some experience with other similar tools like xcodebuild or Jenkins CI/CD pipeline management system in general (which I do). It has everything one needs - from simple tests creation through full-blown integration testing of iOS apps using XCTest framework which allows running your app under various conditions as well! The only thing that could be improved are more advanced features such as automated acceptance criteria definition via JSON files etc., but this would require additional development effort so far we haven't found any need yet :) We're solving our problems related mostly around QA automation by creating custom scripts written directly inside TestCases classes instead writing them manually into each file before execution time.
