Wow this is one awesome, versatile timer! I was looking for a more flexible interval timer, which is what this is but WAY more. I really like that you can program in voice commands (such as in the Fight Gone Bad example workout) so that you don’t have to remember your workout sequence or look at the iPod or whatever to see the sequence. The sample timers are excellent and have given me ideas to program in additional ones. Easy to program & use!
