The Alchemist Code
Jump Rope Coach
Jump rope workouts with a voice-guided HIIT interval timer
Jump Rope Coach turns any jump rope into a structured interval workout. Pick a session for your level, press start, and voice and vibration cues tell you when to jump, rest or switch to technique, so your eyes can stay off the screen. It works offline, with no account and no branded rope required.
Workouts by level
Six free guided interval workouts from beginner to advanced, with levels that unlock as you complete sessions.
Voice-guided HIIT timer
Voice and vibration cues you can turn on or off, and the screen stays on for the whole session.
