Except that it's not an OS X application (like the OP requested).
He´s asking for a free OS X app ;-)
Doh!
If it helps at all, I have a dock for my iPhone that I use while at my desk. Hours is a helpful companion.
This is the only app I actually used the longest. However the lack of "cloud backup" kinda sucks. I'm pretty sure they are working on that though.

Designer News is a large, global community of people working or interested in design and technology.
Have feedback?
Hours is excellent.
The app also makes great use of iOS 8 widgets by letting you start and stop timers right from the widget.
EDIT: Apologies! This doesn't fulfill your request for an OSX app, but Hours is still recommended.
