The timer apps now available are ok but they all are missing the interval timer functionality like the "GymBoss" app for iPhone. Is it possible to add interval functionallity to the Pre?
Say I want to run in place for 30sec then rest for 10sec and I want to do this for 8rounds, an interval timer would beep for every interval and at the end of the last round it would have a prolonged distinct beep. (and vibrations)
