Pretty great, a few shortcomings though.

Useful app, but I have a couple suggestions:

A) Menu bar icon would be great as some recommended. Maybe when you click on it it would tell you how much time is left until the next break - when I switch over to the program its not easy to tell whether its on or not just by looking at it.
B) Maybe give us the option to pick a photo for the break background? Not necessary, but it might be nice.
C) Make it so theres no minimum time to set. Id like to work 50 seconds, then have 10 seconds of break for my microbreaks, but the "work" time isnt divisible by seconds so the shortest work time I can do is 1 minute.
D) Have the ability to see a running total of how many breaks have occurred since the start of the session.

Overall this app is very neat, though, and Im glad its free.
