Questions before you prop up the phone
Straight answers about what Form Fighter is, what you need, and what it is not.
What is Form Fighter?
Form Fighter is a mobile web training tool for people who practice boxing, kickboxing, Muay Thai, or MMA striking alone. Live camera practice uses standard 2D pose feedback on the strikes in your discipline, then names one weak mechanic and drills it out loud. You can also upload a side-on shadowboxing or bag-work round with one fighter clearly in frame. The upload scan looks for clear strike moments across the 11 standard 2D techniques and coaches the clearest one when evidence is strong. Weak or ambiguous evidence is refused, not guessed. Eligible sessions may also receive enhanced movement review across a wider technique roster when that surface is available.
What’s a good app for shadow boxing form if I only have a phone?
Form Fighter is built for that use case: a phone camera, standard 2D pose feedback, one weak mechanic per set, then a live corrective drill out loud so you can re-throw. No bag or wearable sensors required. It is not a human coach and does not replace pads or sparring. Android is coming soon — train in the browser on Android today.
Is Form Fighter an AI boxing coach?
It uses phone-camera pose tracking and automated cues — not a human coach. Live camera practice gives standard 2D pose feedback. Uploads can add 2D camera feedback for jab, cross, hook, uppercut, overhand, teep, side kick, knee, low kick, roundhouse, and head kick. Enhanced movement review is available for supported sessions when eligible (boxing-sport sessions stay punches-only).
Do I need a heavy bag or wearable sensors?
No. You need a phone, a quiet room, and enough space to throw with your full body in frame. No bag, no sensors, no appointment. Upload analysis is optional: standard 2D camera feedback currently grades jab, cross, hook, uppercut, overhand, teep, side kick, knee, low kick, roundhouse, and head kick from a side-on clip when evidence is clear.
How does live camera practice work?
Prop the phone so your whole body is in frame, throw, and Form Fighter watches 2D pose. It names one weak mechanic, then speaks cues during a corrective set. Voice commands like ready, pause, go, and finish keep your hands free mid-round.
What can the camera actually see?
From a usable frame it can observe guard height, visible hip rotation, balance, and recovery. It cannot measure contact force, bag force, punch power, opponent distance, or weight transfer through the floor, and it does not diagnose injury.
Which strikes are supported?
Live camera practice (standard 2D) supports the strikes in your discipline: boxing — jab, cross, hook, uppercut, overhand; Muay Thai — jab, cross, hook, uppercut, teep, roundhouse, low kick, head kick, knee (no overhand, no side kick); kickboxing and MMA — the full standard 2D kick/knee set including overhand and side kick. Switch kick is not available in live practice. Upload analysis (standard 2D) looks for clear strike moments across jab, cross, hook, uppercut, overhand, teep, side kick, knee, low kick, roundhouse, and head kick. Each is scored only after identity evidence and a valid cut. Weak or ambiguous evidence is refused, not guessed. Switch kick is not part of standard 2D upload. Enhanced movement review is available for supported sessions when eligible. It can cover jab, cross, hook, uppercut, overhand, teep, roundhouse, low kick, head kick, side kick, knee, and switch kick. It does not run on every live or upload session. Boxing-sport sessions stay punches-only. Availability may vary.
Can a phone camera really tell what is wrong with my technique?
It can name a visible leak in guard, hip turn, balance, or recovery from the angle you gave it. That is useful for solo work a mirror hides. It cannot feel your weight, measure force, or replace a coach in the room. Scores are estimates and can be wrong with poor lighting or framing.
Is there a free trial?
Free scored sessions to start, no card required. Form Fighter Pro then includes a 7-day free trial. Plans are $3.99/week, $13.99/month, or $32.99 every 3 months (USD — confirm on /pricing). Drill and Learn stay available without a subscription.
Does video leave my phone?
Clips you record or upload are processed for pose landmarks and coaching results. Analysis may run on your device and/or our servers. See the Privacy Policy for what is stored, why, and how to delete it.
Does it work on iPhone and Android?
Form Fighter runs in the mobile browser as a progressive web app on iPhone and Android phones. An iPhone app is on the App Store. Android is coming soon — train in your browser on Android today. Desktop browsers also work for account and review flows.
Is this a replacement for an in-person coach?
No. It is a training aid for the hours you practice alone. It does not replace sparring partners, pads, fight camp, or a live coach.
