It is easy to use, fast and reliable. I have used it for recording my app UI test cases and it helped me to record all the test cases with ease. I didn't find any faults in this tool. The only problem i faced was that sometimes it takes time to start recording after clicking on the Start button. But otherwise, it's a great tool. If you are looking to record your application UI test cases then you should give robotium recorder a try. We were facing some problems while writing and recording our UITests. With robotium recorder we can easily write our test cases without any hassle.
