Frequently Asked Questions
Is Who's In free for fitness class booking?▼
Yes! Who's In is completely free forever. If you charge for classes, we take just 2.7% flat transaction fee. No monthly fees, no hidden costs, no subscription required.
Do my students need to create accounts?▼
No! That's one of our biggest advantages. Students can book your classes with just their name - no account creation, no app download, no friction. Removing signup friction significantly increases booking completion rates.
How does the waitlist work for fitness classes?▼
When your class hits capacity, new sign-ups automatically join the waitlist. If someone cancels, the next person is automatically promoted and notified via WhatsApp or email. Zero manual work.
Can I set up recurring classes?▼
Yes, for free. Make your weekly yoga, fortnightly boot camp or monthly workshop a recurring series when you create it: up to 12 classes are created together, each with its own RSVP list. When the series ends, start the next one.
How do I share my class with students?▼
Get a shareable link for each class. Share it via WhatsApp (one-tap sharing), email, Instagram bio, or post QR codes at your studio. Students click and book in seconds.
Can I track attendance and check people in?▼
Yes! Use our free QR code check-in feature. Display a QR code at your studio - students scan to check in. You see real-time attendance and can export class rosters as CSV.
