I like how easy it was to use for our team of testers who didn't have any previous coding knowledge or technical skills required! It also allowed us access from anywhere which made collaboration much easier as well since we were all in different places at once (we used this during hackathons). There isn’t anything really i dislike about Mozark other than maybe some minor UI issues here & there but they are working hard fixing them so its pretty minimal these days anyways :) We're using mozarks app builder tool mainly because you can create multiple versions without having code written first - allowing more flexibility with what's being tested before going live/release version 1 etc.- Allows cross-browser compatibilityTesting across mobile devices such iOS vs Android.
