The best feature is that I can track my work hours in multiple projects at once. It also is very easy to use for beginners too as it has drag and drop interface which makes it easier than others out there. Sometimes when you are using wakatime while working with other applications like google drive or slack this app will freeze sometimes even though your internet connection still works fine. This only happens if you're doing more then one task at once so not really an issue but just mentioning because some people might have this problem. If you want something simple and friendly to use go ahead and give it a try! You won't be disappointed. Tracking my project's progress by keeping logs of how much time i spend every day coding.
