## What is Circuit Timer?

Build custom interval training circuits and run them with precision timing, voice announcements, and haptic feedback. 
 
CREATE YOUR PERFECT WORKOUT 
Design circuits with unlimited intervals, each with its own name, duration, and alarm sound. Set loop counts on individual intervals or the entire circuit. Choose from
24 alarm sounds, enable voice countdown, or both. 

STAY IN THE ZONE
A full-screen player with a progress ring, countdown timer, and interval timeline keeps you focused. The last 3 seconds pulse to keep you ready for what's next. Voice
announcements call out interval names so you never have to look at your screen.

NEVER MISS A BEAT
Live Activities put your timer on the Lock Screen and Dynamic Island. Background notifications keep you on track even when you switch apps. Start circuits hands-free
with Siri.

APPLE WATCH
Run circuits from your wrist with real-time heart rate zones, active calories, and haptic alerts. Your watch keeps going even when the screen dims with Always-On
Display support.

View workout history with streaks, completion stats, and total training time. Save workouts to Apple Health as High Intensity Interval Training sessions.
