Exactly what I wanted

I tried downloading many timers that apparently supported byoyomi for go matches. However, either the timers were poorly designed, you had to pay for extra timing options, or you could only have one period of byoyomi. Finally, I found this timer and it is just what I wanted. It supports Japanese byoyomi, Canadian byoyomi, and sudden death. Also, you can save your most used timer settings. I agree with the previous reviewer that a confirmation dialogue should pop up once the stop button is hit. However, I consider this a minor issue. I think this app deserves five stars for being the best go timer I have seen in the App Store.

Working well so far

This is a really simple app that does just what it should and no more. Easily set up and use a timer for your go games.

My only suggestion is that there should be a confirmation dialog for the stop button. I'd hate to accidentally press that and end the timer prematurely.
