Features

Everything you need to run classes

The essentials, done well — so the schedule runs itself and you can focus on coaching.

🗂️

Classes & recurring sessions

Define your classes once and let weekly sessions generate automatically across your schedule.

📅

Bookings with capacity

Students reserve a spot; sessions fill, lock, and show as full — no double-booking or guesswork.

QR walk-in check-in

Post a code at the door. Booked students and walk-in guests check in with a single scan.

🌐

Public trainer profile

Get your own profile and clean slug to share. One link sends students straight to your schedule.

📱

Mobile + web, one app

Manage from your laptop, check people in from your phone. Same account, everywhere you go.

📊

Real-time class stats

Watch check-ins land live and track show-up rates so you always know how a session is going.

How it works

From schedule to check-in in three steps

Set it up once and your students do the rest.

1

Create your classes

Set up your trainer profile and add classes with the days and times you teach each week.

2

Share your link & QR

Send students your profile link and post the class QR code at your training spot.

3

Students book & check in

They reserve a spot, arrive, and scan to check in — attendance lands in your dashboard instantly.

Your classes deserve better than a group chat.

Set up your schedule today and let your students book and check in themselves. Free to get started.
