Daily Adaptive Training Coach

Your workout, rewritten every morning. IntervalCoach is an AI training coach for cyclists, runners, and triathletes.

Not a generic "easy day / hard day" nudge. A real coach watching your data and rewriting tomorrow's workout based on how you actually slept.

- Choose which app your HRV comes from. When more than one app writes HRV to Apple Health, Settings → Apple Health lets you pick one, and IntervalCoach reads only that app instead of averaging them all. Switching rebuilds your last 30 days from the chosen app. - Completed activities show a route profile: elevation with climbs highlighted, time spent climbing, on the flat and descending, and a list of climbs with gradient, power or pace and heart rate. - Add a group session to your calendar with how hard it will be, and your plan works around it. - Triathlon is now a race type in the race editor. - You can attach a course to a race you already created. - Coach+ no longer fails with "unknown error" when changing a workout that contains a one-minute segment. - Sending workouts to Apple Watch keeps working after many manual sends. - Walks, runs and other sports are named correctly on the activity screen. - Adding a workout from the training plan offers every sport, with your own sports first. - The goal duration slider shows each goal's own range. - On iPad and Mac, the race catalog is in the sidebar. - Race courses up to 40 MB can now be uploaded, with clearer messages when a file is too large. - Sessions paired with an activity in Intervals.icu no longer show twice on the calendar. - Approving one of several Coach+ suggestions is no longer lost when you leave the chat or type a message. A held approval now says it is waiting for the others. - The Coach+ keyboard can always be put away, with a button in the message box. - Coach+ cards show dates in your language instead of raw timestamps. - Coach+ approval cards say when races are removed too, and show steady steps correctly. - A race that fails to save now tells you why. - Zone scores say when they are based on training volume, and activities explain a missing recovery curve. - Past workouts sent to Apple Watch are cleared automatically, so there is room for new ones. - Session durations stay readable on narrow iPhones.
