Stop training blind. You grind through every round soaked in sweat — but are you actually in the zone, or just guessing? Fixed rest treats a fresh body and a gassed one exactly the same. H11T is the smart conditioning coach that runs your workout by your heart rate, not by feel. You're a data-driven athlete. Train like one. • Smart Rest — your rest ends the moment your heart rate has actually recovered, read straight from your Apple Watch. No more cutting recovery short or wasting it. • AI Coach — get a full workout built around you in seconds. Tell it what you've got, it does the programming. • Pro Studio — design and save as many of your own protocols as you want. Your training, your library. • Boxing IQ — a real round timer with the ring bell, plus rounds that flow with your heart rate. Ready-to-go presets: Amateur, Pro, MMA, heavy bag. Plus the essentials that made H11T a go-to: • Fully customizable rounds, work and rest times, warm-up and cool-down — perfect for HIIT, Tabata, and pro sessions. • Apple Watch support with haptic and sound cues on your wrist. • Apple Fitness integration — calories, heart rate, and activity logged automatically. • Pro stopwatch with millisecond precision for runners and swimmers — ideal for intervals and time trials. The free timer is yours to keep. Premium is the brain on top of it. Who it's for: • HIIT, Tabata, and CrossFit-style athletes who want to train by the numbers. • Boxers and combat-sport fans who want real rounds, smarter recovery. • Anyone done with guesswork who wants every interval to actually count. Train smarter.
