Great App--Works as Advertised
In searching for a good, programable interval timer, I downloaded (and paid for!) a couple of so-so apps before I came across this one, which absolutely blows the others out of the water. Its completely programable, intuitive and--unlike the others I came across--provides real support and instructions. Creating and editing sessions is a breeze, and the interface is clean and, as far as I can tell, bug free. Seriously, drop the $1.99, program it to do what you want, and get down to business.
