About

Sparring Clock

Features
Read full description

Sparring Clock is a boxing and interval round timer built for real training — heavy bag, pads, shadow boxing, sparring, HIIT or circuits. Set your rounds, hit start, and never look at your phone again: the bell, the warning knock and the vibration tell you everything. And when you are the one running the room, Corner Mode turns the same timer into the tool you stand behind. CORNER MODE — RUN THE WHOLE CLASS • Corner board: a black board with a thick phase-coloured border, sized to be read from the far wall • Coach pad: two foot-sized tiles across the bottom of a running timer. Left tile whistles, right tile beeps — mid-round, without touching the clock • Every tile keeps its own tally, with an optional target, so calling thirty means you know you called thirty • Hold a tile and the cue repeats on the interval you set — a metronome you drive by hand • Coach actions: hold the round, add thirty seconds, cut it short, or run it again — the four things you do when a class is not going to plan • Station rotation: split every work block into equal stations and call the change • Class profiles: save a whole set-up — quiet class, kids, pro — and switch between them in one tap • Bluetooth remote: pair any clicker or foot pedal and drive the session from across the mat • Lock the controls so a stray hand cannot end the round WORKS THE WAY A GYM TIMER SHOULD • Loud, clean bell to open and close every round • Wooden double-knock warning before the round ends, so you know when to empty the tank • "Get Ready" countdown before the first bell — you always have time to put your gloves on • Countdown digits sized to be read from across the room • The screen turns deep orange in the last 10 seconds • Foot zone: tap the top of the screen to pause or resume, hold it to reset — it works with gloves on, or with a foot when the phone is on the floor PACE AND PROGRESSION • Pace metronome: steady ticks through every work round. Set strikes or jumps per minute, accent the downbeat, and let the tempo climb round by round • Auto progression: finish a workout and it gets a little harder next time — work grows toward your target, rest shrinks toward your floor • Periodic interval beep on its own period, for pace or drill changes EVERY SETTING IS YOURS • Round and rest durations, round count, sets, and rest between sets • Optional warm-up and cool-down, and an adjustable end-of-round warning lead • Round cue: boxing bell, gong, whistle or a soft chime, struck one to three times • Warning cue: wooden knock or beep, one to five hits • Ticking countdown over the last seconds, on or off • Vibration cues with light / medium / heavy intensity, adjustable per event • Master and per-cue volume, and a choice of how background music behaves • Optional voice announcements — off by default, no talking unless you want it • Settings are five plain tabs: Sound, Pace, Screen, Coach, General READY-MADE PRESETS Boxing (Pro), Boxing (Amateur), MMA, Muay Thai, Kickboxing, Tabata, EMOM, HIIT and Quick Spar — start in one tap, or build your own workouts and reuse them. BUILT FOR THE MIDDLE OF A WORKOUT • Screen stays awake, and can raise its brightness, for the whole session • The bell still rings with the screen locked or while you're in another app • Cue, Hold and Cut sit on the ongoing notification, so you can run the round from the lock screen • Progress as a ring or a bar, counting down or up, in four text sizes • Dark theme by default, plus pure black and light themes • Training history with your streak, so you can see what you actually did • English and Turkish NO ACCOUNT, NO ADS, NO INTERNET Sparring Clock has no sign-up, no ads, no tracking and no analytics. It never connects to the internet — your workouts and history stay on your device and nothing is ever uploaded. It works exactly the same in a basement gym with no signal. Free. Just a timer that does its job.
