Onlyoss is built around what a gym like that needs to know: who came, who stopped coming, and the message that brings them back.

A school’s day on Onlyoss, in two minutes.

Recorded on a sample school: check-in at the door, the first month of messages already written, the Wall of Fame and the school’s own page.

The tour on a sample school: students check in at the door, their first month on WhatsApp is already written, a 30-day challenge, the Wall of Fame, the school’s own page, and a student sharing a confirmed rank.

Gym management software

Run your school. Your marketing comes ready.

Run your school

  • A chat on a sample school's page: a visitor asks about beginner classes, the AI assistant gives the class times and books a free trial for Friday.

    An AI assistant that answers and books trials

    Visitors ask on your page. It answers from your own details, day or night, and books their free trial.

    From Pro

  • The coach's register for today: six students, two already ticked because they scanned in at the door.

    Check-in and attendance

    Students scan a QR code at the door and the register fills itself. No app to install.

  • A school page: two instructors and three members, each with the belt the school confirmed.

    Members and belts

    One member list, and every rank confirmed by the school that awarded it, on your school's page.

  • A 30-day challenge table: each student's days trained, friends brought and points.

    Every class counted

    Days trained and friends brought add up per student, in a 30-day challenge.

    From Grow

Also: who stopped coming, with the WhatsApp message ready, and a payments record with renewal dates (from Grow). Onlyoss never takes the money.

Ready-made marketing

  • A ready Instagram post: this week's classes for a sample school, with its name, address and the Onlyoss logo.

    A year of posts, already made

    Your timetable, belts, events and holidays, made with your name, logo and classes. Download and post.

    A starter set on every plan, the whole year from Grow

  • A ready ad sign-up page on a phone: "Your first Jiu-Jitsu class is free", three reasons and a "Save my place" button.

    A sign-up page for your ad

    Pick a design for your art, add your class, run your ad.

    Ad pages: an add-on, or 3 included on Pro

  • A ready Wall of Fame post: a student's first place in the 30-day challenge, the school's name and a "Join the family" QR code.

    A post your students share

    When a student wins, Onlyoss makes the post and the story, with your school's name and link.

    From Grow

  • A ready WhatsApp welcome message to a new student, written by Onlyoss and waiting for the school to press send.

    The message, already written

    Welcome, day 3, bring a friend, one month in. It opens on your WhatsApp; you press send.
