IntervalCoach
Train for the day you're actually having, not the day you planned for.
A coach that understands your full picture: fitness, recovery, and the life around your training.
It reads 60+ recovery signals, your goal event and your week, then adapts today's session to match. Across every sport you train: cycling, running, trail, triathlon, swimming and strength.
Works with Apple Health · Google Health · Whoop · Intervals.icu · Garmin · Polar · Wahoo · Oura · and more

What do athletes say about IntervalCoach?
IntervalCoach is rated 4.8 out of 5 from 71 ratings on the App Store. Below are reviews from the App Store and Google Play, plus athletes we have featured on the blog.
4.8from 71 ratings on the App Store“Finally a well executed adaptive app that truly feels "worth it". The interface is clean and well thought out and simply talking to the AI coach can restructure your calendar. Using intervals.icu as the hub, these changes update my Garmin computers automatically.”
“I've been using IntervalCoach daily for more than six months. IC uses AI to provide adaptive training plans, detailed workouts, readiness, load management, etc. All of this is packaged in an attractive and intuitive UI. IC has helped me develop a long term plan (and stick to that plan!) for future A-races. […] This app provides the best combo of functionality, speed of development and affordability.”
“The App is made for athletes. Very good overview of all helpful details, when you start in a new training day (sleep, HRV, mood, etc. is analyzed and your training plan adapted if needed e.g. if HRV is low or you had a bad sleep). […] For me it is the best App on the market so far!”
“That's really impressive, tackling all of these things so quickly! Good luck finding that level of support from a big company like Google or Strava.”
“For me this is the best app for managing your training.”
