It's very easy to use, has all of my filters set up so that I can see exactly what matters most in terms of numbers and insights, and it allows me to quickly share reports with clients or colleagues by simply sending them a link via Slack or HipChat.
The UI could be improved - it would be nice if you had more control over how things look (i.e., font size) when showing your data in different ways. I like being able to quickly send out metrics as well as trends in real time, allowing people who are not directly involved in a project have access to important information about their projects' performance.
