From the developer:
KTimer is an extremely simple timer made to be used with your keyboard. It takes advantage of Mountain Lion's Notification Center so it's seamlessly integrated in your Mac working environment.
To start a timer, just type a time such as "1m 30s" and hit enter.
You may want to check out more Mac applications, such as PDFMergeThing, NanoCount or Apimac Clean Text, which might be similar to ktimer.
