Group classes vs 1-on-1 appointments
Acuity Scheduling (Squarespace Scheduling) is an appointment tool: Starter $20/mo, Standard $34/mo and Premium $61/mo billed monthly, about 20% less billed annually (Acuity's own pricing page, checked 5 October 2026). It is excellent when clients book a time with a person.
Who's In Studio is built for the opposite shape: many members booking the same class. Starter ($19/mo, or $190/yr) and Growth ($49/mo, or $490/yr) have every feature; the only difference is that Starter covers up to 99 active members and Growth is unlimited. Starter moves up to Growth automatically when you pass 99.
Billed monthly: Acuity Starter $20/mo vs Who's In Studio Starter $19/mo. A similar price, built for a different job: pick the one that matches how your clients book.
Where an appointment tool strains for a class studio:
- • A weekly timetable of group classes with rooms and capacity
- • Memberships and class packs that entitle members to book
- • Waitlists, waivers and front-desk check-in
Who's In Studio: built for the class timetable
- Classes below your minimum headcount cancel themselves a set number of hours before start, and booked members are emailed
- Waitlists promote the next member automatically when a spot opens
- Numbered bike booking for cycling classes: riders pick their bike from a bike map, one rider per bike
- Room rentals: rent rooms by the hour to therapists and other practitioners you approve; they book and prepay online, and a room is never double-booked
- Online-only and hybrid classes: the Zoom, Meet or Teams link goes only to booked members
- Digital waivers (text or PDF, versioned): booking is blocked until the member accepts the current version
- Instructor pay calculation (hourly, per-class or flat monthly) with pay history
- Apple Wallet and Google Wallet membership passes that scan at QR check-in
- Memberships, class packs and free member trials of up to 90 days, with member self-pause where the plan allows it
- 0% Who's In fee on member payments: charged on your own Stripe account
- MRR/ARR, cohort and retention analytics, plus attendance and no-show rates
- Website embed widget and a public booking page at whos-in.app/s/your-studio
