Plan your workout in advance, set your own rules, and we'll remind you what to do and how you wanted it. Log your results in a few taps - a minimalist but smart app keeps your head free for things that matter at that moment, not spreadsheets or wondering what's next. Just show up - we'll handle the rest.
What exactly is Hup! Training Assistant?
Hup! Training Assistant is a workout builder and tracker for cardio, HIIT, strength training and calisthenics - all in one app - on iPhone and Apple Watch, with per-exercise execution strategies and rest by heart.

Log gym workouts, get guiding haptics

A Tabata and interval timer with rest-by-heart
No time to waste looking at the screen - focus on your heart, and your watch notifies you with haptics or voice when the interval ends. Rest interval wasn't enough? Combine the rest timer with target heart rate to recover properly before the next round. Ready, steady, hup!

Cardio training with a target heart rate or speed
From short intervals to long endurance sessions, set a target heart rate or speed and Hup keeps you on track - it tells you when to push and when to ease off. Review your past sessions, adjust your plan, and watch your results improve, ride after ride, run after run.

Train with only your Apple Watch
No need to carry your iPhone - Hup runs fully on Apple Watch alone. On the calisthenics bars, mid-run through the forest, or halfway up a climb: leave your phone, your notifications, and the noise behind. Just you, right now, and your watch.
