CUSTOM CIRCUITS Work, rest, warm-up, and cool-down β€” each with its own name and free-form duration. Drag to reorder. Insert a segment anywhere. Set rounds. Presets include 20/10 sprint, 45/15 HIIT, EMOM 12, and a focus cycle. CUES THAT KEEP YOU HONEST Halfway beep and 3-2-1 countdown, including short intervals. Haptics on every transition.
