TMetric is exactly what I needed to gather time management statistics. The interface is a breath of fresh air. I was able to hit the ground running from the start due to the easy to navigate UX. I can't believe that this tool is free. I will be recommending that my colleagues with larger user bases try TMetric as a replacement for their unruly time management solutions.
Nothing, as of right now. I have yet to use the mobile or desktop app. I will update my review with recommendations on those interfaces.
If you're looking a simple way to get deep metric reports of yours and your employees time spent then this is the product for you.
I have some clients that require a very strict accounting of billable hours. I also have some that allow for less stringent accounting. TMetric gives me the flexibility to categorize these projects and be as granular in my reporting as the client requires.
