Free Tool — No Password, No Install

A Round Timer Built for the Mat, Not a Kitchen Counter

Cast it to the TV on your wall, set your rounds, and run the class. It is free, there is no password or install, and it was built for a working martial arts academy rather than adapted from a generic interval app.

Start rounds without walking off the mat

The thing that actually breaks a class is having to stop, cross the room and poke a laptop between rounds. The timer pairs with a remote controller on your phone, so you start, pause and skip rounds from wherever you are standing.

  • Phone controller — start, pause, reset and skip from the mat
  • Round and rest times set independently, in seconds
  • Round-start, round-end and countdown sounds, each replaceable with your own audio
  • Big, readable countdown designed to be seen from across a mat
  • Runs in any browser — cast it to a TV, run it on a tablet or an old laptop

Put your own gym on the screen

Upload your own background and logo so the screen on your wall looks like your academy instead of someone else's software. Every image below is a real background running at Creston BJJ.

Free timer vs. your own timer

The free timer is the real thing, not a crippled preview — set your rounds and run your class. The shared version is open to anyone, so give us an email and we will issue you a private one on your own link. A DojoMesh account then makes the screen fully yours: your logo, your backgrounds, your sounds.

One timer per academy, driven from your phone — put a screen in every mat space and they all count down together off the same clock.

Why the free one is worth using anyway

The timer is one piece of DojoMesh, the platform Mark Artyniuk built to run his own BJJ academy — billing, attendance, belt tracking, messaging and the academy website. The timer costs nothing and needs no account because it is genuinely useful on its own. One thing to know: the free timer runs on a shared demo clock, so if someone else is using it at the same moment you will both be driving the same countdown. Your own account gets a private one.

Common questions

Yes, and it stays free. You can open the shared timer and use it straight away with no details at all. Give us an email address and we will issue you a private timer on your own link instead, so nobody else can start or pause your rounds — still free, no password, nothing to install.

Yes. A separate controller screen drives the timer remotely, so you can start, pause, reset and skip rounds from the middle of the mat instead of walking to the laptop.

Yes — custom backgrounds, your logo, and your own round-start, round-end and countdown audio. Branding is configured per academy inside DojoMesh.

Any device with a browser. Most gyms cast it to a wall-mounted TV or run it on a tablet or an old laptop pointed at the mat.

Yes. Open the timer on as many screens as you like and they all follow the same clock, kept in sync by the server, so a countdown started from your phone runs identically in every room. Note that it is one timer for the academy rather than separate independent timers per mat — everyone is on the same round.

No — the free version runs on a shared demo clock, so if another visitor is using it at the same time you are both driving the same countdown. A DojoMesh account gives your academy its own clock on a private URL.

It runs the whole academy — recurring billing, attendance with AWOL alerts, a configurable belt and grading system, two-way SMS and email, scheduling, pro-shop POS and your website. $50/month flat for unlimited students.

Try it on your own academy for 60 days.

Unlimited students, every feature, one flat price. Free assisted migration from whatever you're running today.
