The best part is that it tracks my hours, projects, tasks etc., in real-time without any manual intervention or setup required! I can easily see how much time I spend per day/week working with each project; what percentage of work has been completed so far? What's more important - number of hours worked or amount of billable hours achieved during this period? There isn't anything to dislike about Myop as such.
It does exactly what we need from an HR perspective. We are able to track our employees' activities at all times (even while they're out of office).
