IntervalCoach vs RunSolver

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. WHAT YOU GET - Daily readiness from HRV, sleep, resting heart rate, form and training load - Workouts that adapt to your recovery, with power, pace or heart rate targets - A training plan built toward your goal event, with phases and weekly targets - Coach+, a conversational coach that knows your training and can adjust your plan - Race Recon: the climbs, pacing and fuelling of your race course - Post-workout analysis, with what you actually did next to the plan - Signals grouped by recovery, sleep, HRV, load and body - Cycling, running, trail running, triathlon, swimming, strength, walking and hiking, with bike-to-run bricks - Training for a Hyrox: your plan builds the running and strength work the race asks for - Weekly summaries, monthly progress reports and a home-screen widget - Clubs with a shared feed and fair leaderboards FOR COACHES With the Coach Plan, a coach gets a roster sorted by who needs attention, one inbox for approvals and a view of the whole squad.
