Circuit Timer vs Interval Timer

Build your own interval circuits for HIIT, Tabata, boxing rounds, EMOM and circuit training, then run them with precise timing, voice announcements, sounds and haptics. CREATE YOUR PERFECT WORKOUT Design circuits with unlimited intervals, each with its own name, duration and alarm sound. Repeat single intervals or the whole circuit, by count or for a set time. Choose from 24 alarm sounds, a spoken countdown, or both. STAY IN THE ZONE A full-screen player with a progress ring, countdown and interval timeline keeps you focused. The final seconds of each interval pulse so you're ready for what's next, and voice announcements call out each interval by name, so you never have to look at your screen. TRAIN WITH YOUR MUSIC Interval sounds play over your music instead of pausing it. The current interval and countdown stay on your Lock Screen and in the Dynamic Island, and cues keep working through phone calls. Start any circuit hands-free with Siri. APPLE WATCH Run circuits from your wrist with live heart rate, heart rate zones, active calories and a tap at every interval change. Starting a workout on your iPhone? Your watch follows along with the same taps and your heart rate. A Smart Stack card keeps the current interval in view, even with the app closed.
