Hi, good and simple design. Liked it. But when I open the webpage, it is stopped at 25:00. But if I click to another link like "Short Break", it suddenly starts. And when I click Reset, it resets but starts again. I couldn't find how to stop it at 5:00 :)

Pretty cool. You might add a counter to keep track of how many breaks you have taken, since you usually take a longer break after every four short ones.
