Has anyone found a good interval/HIIT app that uses haptic notifications on the watch. I really like Intervals for the iPhone, but the watch app doesn't use haptic notifications. I found Silo, which does use the haptic on the watch, but it is very limited - 6 exercises and only one workout. A rest period uses one of the allotted exercises.
I use this HIIT app with haptic notifications https://itunes.apple.com/us/app/hiit-the-most-easy-to-use-hiit-tabata-timer/id1256319392?mt=8
