Interval training for your Apple Watch
SILO uses the Taptic Engine on the Apple Watch to alert you between intervals. Do your HIIT workouts without having to watch the clock or disturb others nearby.
Simply set up your workouts on your iPhone. When you're ready, just pull up Apple Watch and press "GO". A tap on the wrist cues you at each interval. During your workout, glance at the watch for status and to preview the next activity.
For best results, turn on airplane mode right from your Watch. This lets you avoid false positive haptics during your workout.
At the end of a workout session, SILO connects with HealthKit and displays your heart rate, calories burned, and workout time.
Add up to three Presets from your phone right to your watch. On the iPhone, set up your interval activities and the number of rounds. You can edit the names of the presets and the activities – hit Sync and you're all set.

Ratings and Reviews
Solid Interval Timer
Silently taps me on the wrist during workouts, just what I needed! I've searched the app store left and right, and this is the best (if not only) HIIT timer for the Apple Watch, that actually works right. What I love the most is it's simple and non-cluttered like the other stuff. This app has one job and it does it well, and then some!
Haptic feedback won't work
... whenever screen goes off. I wanted to use this for doing a set of streching excercise but that makes it the app practically unusable.
