Set preparation time, boxing rounds, rest, and repetitions, then press Start. You do not need to create a saved workout to use the timer. BUILD AND SAVE YOUR OWN WORKOUTS Create separate presets for different training days, disciplines, or goals. Combine exercises, preparation, rest, cooldowns, and repeat blocks in your own sequence. Adjust each step's duration and repeat groups of steps instead of adding them individually. Save your routines and reuse them for your next session. CHOOSE FROM MORE THAN 1,000 EXERCISES — OR CREATE YOUR OWN Browse exercises for striking, grappling, warm-ups, and cooldowns. Search for a drill and add it to your workout. Create custom exercises when you need something different, with your own name, description, and optional photo or video link. CUSTOMIZE EACH EXERCISE Change exercise names to match your drills and combinations. Choose an icon and color for each exercise so you can recognize it during training. Set individual durations and arrange the sequence around the way you train. Give saved workouts their own icons and colors to distinguish your routines. MANAGE YOUR SESSION WITH A TAP Tap an exercise icon to open its actions. View exercise details, move a step, duplicate it, or copy and paste it into your session. Build longer routines from the drills you already configured. FOLLOW EVERY ROUND The active timer shows your current exercise, its remaining time, the next step, and the time left in the session. See your progress through the workout and use sound assistance with your chosen round bell. Pause and resume, restart, or move forward and back through the sequence when your session changes. KEEP YOUR TIMER IN VIEW Follow an active workout with Live Activities on the Lock Screen and Dynamic Island. Use Home Screen and Lock Screen widgets to access and control your session. CHOOSE YOUR APP'S APPEARANCE Use light mode, dark mode, or follow your system appearance. Pick an accent color for the main action buttons. Customize exercise and workout icons separately, and unlock alternative app icons as you train. REVIEW YOUR COMPLETED SESSION See completed rounds and segments, active time, rest time, total duration, and skipped time. The workout summary also includes an estimated calorie burn. Use the quick timer for your regular rounds or build a saved workout with different drills and intervals. Box Timer gives you control over the sequence, timing, names, icons, and colors in one app.
