Muay Thai · Kickboxing · Boxing
Someone in your corner, calling the shots.
Combos, defence and movement, called out loud while you shadow box, hit the bag, or hold pads for someone. You don't get to plan the round — you answer it. Real Muay Thai styles, real combinations, and never the same round twice.

It never calls the same round twice.
The calls come fresh every time, so you spend the whole three minutes a half-beat behind — reacting, scrambling, catching up. That's the fun of it, and it happens to be the thing worth training. You cannot practise reacting to a sequence you already know is coming.
Why people keep opening it
Simple to start. Hard to get bored of.
No account, no setup, no gear beyond whatever you already train with. It works in front of a mirror, in the garage, in a hotel room at midnight — and it holds up on the four hundredth round as well as the first.
When you want a sequence in your body, not a surprise.
Some nights you don't want to be surprised — you want one long combination beaten into you until you stop thinking about it. Switch the calls to sequential and the round becomes a drill instead of a scramble.
Southpaw mode flips every "left" and "right" so you're not translating mid-combo, and calisthenics drops bodyweight work between strikes when you want the round to cost you something.
Some nights you want to kick. Some nights you want to bang.
Pick the one that suits how you feel and the whole round bends around it. Or stack a few and let them collide — a knee-heavy exchange turning into a low-kick trade is exactly the thing you want to have met before it meets you.
Rounds, length, rest and difficulty are yours to set. Or strip it back to a plain interval timer with no calls at all.
Put your coach's homework in it.
Build a style from scratch and fill it with whatever you're working on — the three combinations you got told to fix on Tuesday, the setup that keeps catching you, a list of nothing but your weak side. Name it, star what you reach for, and it lines up next to the rest as if it shipped with them.
Your sets export to a file and import back, so a phone upgrade doesn't cost you the work.
Never trained before? Start at the first jab.
A guided path that assumes you know nothing. It starts with stance and two punches, and each session adds a couple of techniques while keeping everything from the last one in play. By the end you can answer any call the beginner style throws at you.
Nobody drops you into a round full of words you don't know and lets you feel stupid about it. That feeling is why most people quit an app like this in the first week, and it's the one thing this is built to avoid.
Heard a call you didn't know? Go look it up.
Nothing gets shouted at you that you can't go and look up. Every technique has a lesson behind it — punches, kicks, knees, elbows, clinch and defence — drawn as a figure you can open and step through frame by frame until the shape makes sense.
Not beginner, intermediate, advanced
The styles are the real ones.
Muay Thai has always sorted fighters by how they win rather than by how long they've trained — the puncher, the kicker, the knee fighter, the technician. That's the framework this is built on, and every one of them carries its own list of combinations. Not one shared pool reshuffled under a different name.
Muay Mat
The puncher
Heavy hands, body work, and the low kick that comes off them.
Overhand, 4 to the Body, 3 to the Body
Muay Tae
The kicker
Long range, round kicks in series, teeps to hold the distance.
Right Low Kick, Right High Kick
Muay Khao
The knee fighter
Pressure, the clinch, and knees from every entry into it.
1 2, Clinch, Double Knees
Muay Femur
The technician
Read it, take it, make them pay — catches, sweeps and counters.
Catch Kick, 2 3, Right Knee, Sweep Right
It goes past the list. In Muay Tae the lead check comes up three times as often as a normal entry and the rear check twice, because a kicker's round is mostly checking — Muay Femur doubles both, the technician's defining habit. The frequencies are tuned style by style, so a round doesn't just use the right techniques, it feels like the fighter it's named after. Muay Sok is there for the elbows.

The full list
Twenty of them, counting the ones we made up.
The traditional styles, plus a few built around a single idea — the low kick, the spinning stuff, the shot you answer with.
When the last bell goes
Finish the round. Send the card.
Every session ends on a card built from what you actually just did — the styles you picked, how hard, how many rounds, how long, and how many shots you answered. Save it, post it, or send it straight to whoever you train with.
That last one is the one that works. Trading cards with a gym buddy on a Tuesday night is a better reason to get the round in than any streak counter — nobody wants to be the one who didn't send anything. It holds up whether you're in the same gym or three time zones apart.
How it works
Nothing to learn before you can start.
Choose your styles
One, or several. Not sure? Take the guided path and let it decide for you.
Set the round
Rounds, length, rest and difficulty. Three minutes with a minute back is a fine place to start.
Hit start and listen
Bell, then calls. Put the phone down and don't touch it again — the session writes itself into your log when the last bell goes.

US prices; the stores convert and may round for your region, and the price you're charged is always the one the store shows you at checkout. Pro is bought through the App Store or Google Play, so it can't be purchased from the browser version — but the free rounds run there with nothing to install.
Questions
The things people ask first.
What can I do for free, and what needs Pro?
Free: the round timer and every setting on it, three styles — Timer Only, Freestyle and Nak Muay Newb — the first three levels of Start Here, the jab and cross lessons, your workout log, and the completion card at the end of every session.
Pro: the other seventeen styles, the rest of the guided path, the full technique library, styles you build and edit yourself, the training options — southpaw, calisthenics and ordered callouts — and the charm ladder. It's bought in the app, through the App Store or Google Play.
Are the styles just names, or is the content actually different?
Different. Muay Khao is built around entries to the clinch and knees off them; Muay Tae runs kicks in series and teeps to hold range; Muay Mat is hands and the low kick that comes off them; Muay Femur is catches, sweeps and counters. The frequencies differ too — a Muay Tae round calls the lead check three times as often as a normal entry, because that's what a kicker's round is mostly made of.
Does it work without a signal?
Yes. The native apps are fully offline. The web version caches itself on first visit, so once you've loaded it once, a dead gym basement is fine.
Will it talk over my music?
It plays alongside whatever you're listening to rather than stopping it. On Android, some device and headphone combinations handle the ducking better than others — if the balance is off, turn the call speed and volume up in settings.
Shadow boxing, the bag, or pad work?
All three. Shadow boxing suits faster calls and more movement; bagwork suits slower calls and longer combinations; on pads it calls for both of you, so the person holding isn't the one deciding what comes next either. There's a write-up on the difference.
I don't know any of these techniques yet. Is that a problem?
No — that's what the Start Here path is for. It begins at stance and the jab, introduces a couple of techniques at a time, and every one of them has a lesson with a reference figure attached. Start at level one and go.
I bought the app back when it was paid. What happens to me?
You keep everything. Open the app and it restores your access on its own; if it doesn't, there's a manual claim on the plan screen.
Is my training data sent anywhere?
