01What’s in the box
Everything a studio needs. Nothing it doesn’t.
Nine things, done well. No enterprise modules, no AI up-sells — just the work that happens on a Tuesday morning, and the fun that keeps members coming back.
Get paid, see it land
Sell packs and memberships in-app. Watch revenue arrive in real time. No per-booking cut, ever.

Bookings & automatic waitlists
One booking link. Members book themselves. When someone cancels, the next person on the waitlist gets the spot — automatically.
Self-serveAuto-fillOne link
A member CRM that watches your back
See who’s active, who’s lapsed, who hasn’t shown up in three weeks. Reach out before they quietly unsubscribe.
Lapsed alertsAttendance history
Passes & memberships
Class packs, monthly unlimited, intro offers. You set the rules; members see exactly what they own.
Workouts & WODs
Program a session once, reuse it forever. Push the day’s WOD to the booking page.
Attendance & check-in
Tap members in as they arrive. No-shows and streaks log themselves automatically.
Leaderboards, built in
Score a WOD and it ranks itself — Rx and Scaled side by side. Members chase their spot from their phone. The fun part, done for you.
Rx / ScaledLive rankingPRs
One inbox for everything
Broadcast a cancellation. Message a no-show. Answer support threads. All tied to the member record, all in one place.

02Studio + members
One studio. Two apps that talk to each other.
You run the week from the dashboard. Your members live in an app built for them. Tick someone in, and a streak lights up on their phone — automatically.

04Loved by studios
Studio owners don’t switch software often. They switch to this.
Real studios, real rooms, one to five instructors — the people ClassSlotter is actually built for.
“We ran the whole studio through a WhatsApp group for two years. Moving to ClassSlotter gave me my evenings back — members just book themselves now.”
Marta Lopes
Owner · Maré Studio, Lisbon
“Setup took 40 minutes. The member app is the part athletes actually rave about — the streaks and leaderboard keep them coming.”
Joel Andersson
Head Coach · Northside CrossFit
“No per-booking fees was the whole reason we switched. We kept every euro of our class sales and the dashboard is genuinely calm.”
Ana Reis
Founder · Flow Collective
“It looks and feels like software from a company ten times the size. Members assumed we were a big chain. We’re three instructors.”
Karl Vogt
Owner · Iron & Oak, Berlin
“The waitlist auto-fill alone pays for it. A spot opens, the next person gets it, I do nothing.”
Sofia Marques
Owner · Studio Nove, Porto

Questions studio owners ask us.
If yours isn’t here, write to hello@classslotter.com. A founder replies.
Really free, and no card. You get full access to every feature and both apps for 30 days. We only ask for payment details if you decide to keep ClassSlotter after the trial — nothing is charged automatically, and you will not wake up to a surprise bill.
If you keep going, it is €59/month flat — unlimited classes, bookings, members and instructors, both apps included. If it is not for you, do nothing and the trial simply ends. You can export everything as CSV on your way out.
None of the above. €59/mo flat covers unlimited classes, bookings, members, instructors and admin seats. We do not take a cut of your class sales or membership revenue.
Those tools are built for chains with 20+ rooms. ClassSlotter is built for the studio with 1–5 rooms that does not want a 47-tab dashboard. A third of the features, none of the per-booking fees — and a member app your athletes actually open.
Yes. Send us your member list as CSV (or screenshots of your WhatsApp group) and we will import everyone, including credit balances and pass expirations. We can do it on a call during your free month.
Yes — native iOS and Android apps. Members download from the App Store or Google Play, sign in once, and book from their phone. They also get streaks, WODs, leaderboards and PRs. Push notifications for booking confirmations, waitlist moves and class reminders.
Under an hour for most studios. Add your classes, set capacity, share your booking link. We will get on a call with you if you would rather have help — it is included.
