The instinct is within a hair's breadth of being the perfect gym rat's weightlifting set timer. The one missing feature is that, every time that the user cycles through the timer, there should be a lap count on that. As you can imagine, when one lifts weights with headphones blaring music, this is what you want:
1) To be able to time your rest between sets of weight lifting.
2) When the programed rest time has elapsed, a vibration alarm (the instinct has this which is awesome).
3) To be able to track how many sets you've done so far in total. This is what I feel is missing.
Right now, I wear one of these in addition to my instinct in order to get the functionality: SportCount Countdown Timer | Sportcount. It's annoying to have to wear a separate time keeping device for this purpose. I paid nearly as much for the Sportcount as I did for my instinct too. So I feel that there's a real market opportunity with this.
Note that I realize that there is a preprogrammed weight training app for the instinct. It does not do what I'd like it to since it counts up instead of down.
Thanks,
