🥊 Shadowboxer

A boxing combo caller for training alone — the coach shouting numbers at you, without the coach.

Practice

Calls combinations out loud on a randomised beat while a round timer runs.

• Full 1–6 number system. 1 jab, 2 cross, 3 lead hook, 4 rear hook, 5 lead uppercut, 6 rear uppercut. A trailing b means body: 3b.
• 105 combinations across four difficulty tiers, with defense (slip, roll, pull, weave, parry) and footwork (pivot, step back, angle out, circle) woven into the higher tiers.
• Randomised pace. A fixed metronome trains anticipation; the randomness slider scatters the gap between calls so you have to actually react.
• Rounds and rest with a synthesized ring bell and a ten-second clapper warning.
• Stance aware. Numbers are relative to your stance; switching to southpaw flips the directional cues ("circle left" becomes "circle right") and relabels which hand throws what.
• Filters for individual punches, difficulty, combo length, and whether defense or footwork appear at all.
• Your own combos. Type them how your coach says them — 1232, 12 step back 632, 123 slip step body 3 head 3 2 all parse.
• Screen wake lock, session history, punch breakdown. Space pauses, Escape ends.

Study

Not built yet. Planned:

1. Film breakdown — drop in a video file and get a timeline of what was thrown, labelled in the same notation, using in-browser pose tracking. A YouTube link can't be analysed directly: browsers block a page from reading the pixels inside another site's embed.
2. Live camera coach — check whether you actually threw the combo that was called, and how fast you reacted.
