NOT GOOD

Application not good. First negative thing is that it constantly asked you if you want to upgrade to more presets and there is no way of shutting the annoying message off unless you pay your $.99 additional. To me that is a very strong arm tactic that I hate.
There is also no time shown negatively so when the clock hits zero you dont know how much beyond zero you have gone.

It also does not have any sound warnings.

When you hit help but it crashes
Total waste of money twice since I had to purchase more presets to get ride of annoying strong arm messages

PCLOCK is a far better application it has sound and numerals change color at various presets. It also displays negative time as well. Easier to set times with wheel
