From the developer:
Progress Timer is a simple, flexible, and free MacOS timer that shows the time visually. It is ideal for online meetings and games. It has a flexible form, meaning that you can change the size and the position of the timer. You can change the starting time directly on the timer's window or with arrow keys.
Your timer has two sound alerts — 15 seconds before the end and on finish. Of course you can turn them off if you want.
You may want to check out more Mac applications, such as Tea Timer, Quote of the Day or Missing Sync for Sony PSP, which might be similar to ProgressTimer.
