## What is BOX CLOCK?

BOX CLOCK is an interval timer built for functional fitness and interval training. Four formats, AMRAP, EMOM, TABATA and FOR TIME, with a boxing bell for every segment, so you can see and hear it from across the gym.

• FOR TIME: counts up from 00:00. Tap Done when you finish and that time is your score. You can set a time cap.
• AMRAP: counts down a fixed time. Get as many rounds or reps as possible before it ends.
• EMOM: do the set reps at the start of each interval. Whatever time is left is your rest.
• TABATA: defaults to the classic 20 seconds of work and 10 seconds of rest × 8 rounds, switching and cueing for you.
• Bells play even in silent mode. Your music keeps playing.
• Choose when to vibrate: workout starts, each round starts, rest begins, 10 seconds left, final countdown, workout ends.
• The screen stays on during the countdown and the workout. Before you start, it checks media volume, Low Power Mode and battery and warns you about anything that could get in the way.
• Timing and cues keep going when you switch apps or lock the phone. The time left shows on the Lock Screen and in the Dynamic Island, where you can pause or resume. Prefer it to pause when you leave? That's a setting.
• If the app is closed, crashes or the phone shuts down, it reopens at the last pause point. Tap Resume to carry on.
• Add an electronic beat or war drums as background music, with its own volume.
• Combine your result with a photo, or copy the result as text to share.
• Available in Traditional Chinese, Simplified Chinese and English, switchable inside the app.

No network, no account, no ads and no tracking. Settings and workout progress stay on your iPhone. Photos are combined on your iPhone and only leave the app when you tap Save or Share.
