Your training, adjusted to how you actually recovered. IntervalCoach is an AI training coach for cyclists, runners, triathletes, trail runners and Hyrox athletes. It reads 60+ recovery signals, including HRV, sleep, sleep debt, training load and how you feel, and adjusts today's session when the data calls for it. When you are ready, the plan stands. When you are not, it changes and tells you why. TODAY FIRST Open the app and today comes first: your readiness, a coach's outlook and today's session. Next to readiness, a focus tile shows the one thing that matters most right now: a race this week, a health signal, the session you just finished, a load spike, or how your week is going.

Riduck's advantage is in-app purchases (none vs 4) and rating (5.0 vs 4.8). On price, ratings volume, ads and device support there is nothing between them.
