Timey is a timer that lives in the menu bar and takes advantage of the newest features in OS X Yosemite. Timey is the simplest timer possible. It shows in the menubar. Click to start or pause, right-click to reset. Click on options button to change mode or quit Timey. It is that simple. Now, with version 2.1, enjoy handy Today extension, UI redesigned for Yosemite and a fullscreen mode.
