Most people training alone have no idea what their technique actually looks like. Upload a round and BRAWLER breaks it down across seven checkpoints — not a score, but the specific thing that's wrong and the drill that fixes it.
Shadowboxing, bag work, mitts, or sparring. Prop the phone at waist height, get your full body in frame, and shoot a normal round. No special gear, no markers, no external camera.
One round is enough. The analysis reads the whole clip rather than sampling a single punch, so it catches patterns that only show up when you get tired.
Seven checkpoints, each with what was observed, what to change, and a drill to change it. Every analyzed clip stays in your history so you can rewatch it against a later round.
The Seven Checkpoints
Every clip is read against the same seven areas. Below is what each one looks for and the kind of correction it returns — real examples, not marketing copy.
Where your weight sits before, during, and after you punch. Whether your feet stay under your hips or drift wide, and whether you're square to your opponent or bladed.
What a correction sounds like
Your weight is riding on the front foot before you throw. That's why the cross lands short — you have nothing left to push off with. Reset so weight is even, then rotate the back foot to drive.
Hand position at rest and, more importantly, what your hands do while the other one works. The rear hand dropping on the jab is the most common fault in amateur footage.
What a correction sounds like
Rear hand drops four inches every time you jab. Against anyone who counters, that's the shot you get caught with. Keep the knuckles at cheekbone height and let the shoulder do the covering.
Step-drag mechanics, whether your feet cross, how you reset after moving, and whether you're stepping before you punch or punching before you step.
What a correction sounds like
You're crossing your feet moving left. It works until someone steps with you — then you have no base. Lead with the left foot, follow with the right, never let them pass each other.
What you actually throw versus what the situation calls for. Ratio of jabs to power shots, how often you lead with the rear hand, and whether you're headhunting.
What a correction sounds like
Sixty-eight percent of your output is the rear hand. You're loading up and skipping the jab entirely, which telegraphs everything. Double the jab before every power shot for the next three rounds.
Whether punches flow or reset between each one, the rhythm of your two- and three-punch strings, and whether you finish combinations or trail off after the second shot.
What a correction sounds like
You pause a beat between the cross and the hook, which gives away the third shot. Let the recoil of the cross start the hook — same rotation, no reset in between.
Whether your head leaves the centerline at all, whether it moves after you punch, and if you're slipping with your whole torso instead of your head and shoulders.
What a correction sounds like
Your head is static on the exit. You throw, then stand there. Slip right immediately after the cross — it's the same rotation you're already doing, just finished properly.
The distance you actually operate at versus the distance your reach and style call for. Whether you close and stay, or close and reset.
What a correction sounds like
You're fighting at mid-range with a long-range frame. You have the reach to work behind the jab, but you keep stepping into the pocket where you get outworked. Establish the jab first, then decide whether to close.
Video analysis is good at catching what you repeat. It is not a replacement for a coach who can put hands on you, read a sparring session live, or build a game plan for a specific opponent. If you have access to a gym and a trainer, use both — BRAWLER is what runs on the days you're on your own.
Seven checkpoints, specific corrections, and a drill for each one. Record a round tonight and know more tomorrow than you did today.
