Run your school, gym or studio — all in one place

Members and staff, class scheduling, attendance, self-service booking with credits, and payments. Wrenzik keeps your whole organization running — so you can focus on the people in it.

Free to start — no credit card required

Everything included

One platform, every moving part

From the front desk to the classroom floor — Wrenzik replaces the spreadsheets, group chats and sticky notes.

Members & staff

Every profile in one place — contact details, memberships, roles and permissions for your whole team.

Classes & scheduling

Build recurring timetables in minutes. Rooms, instructors and capacity — conflicts caught before they happen.

Bookings & credits

Members book themselves in with class credits or passes. Cancellations and refunds run on autopilot.

Attendance

One-tap check-ins for classes and appointments. Spot no-shows early and see who's really engaged.

Payments

Memberships, packages and one-off charges — recorded in a clean ledger, visible at a glance.

English + Greek

Fully bilingual out of the box. Your staff and members each use Wrenzik in the language they prefer.

3Get paid

Payments and attendance, sorted

Check members in with a tap, keep every payment in one tamper-proof ledger, and see exactly where your revenue comes from — no end-of-month reconciliation marathon.

  • Attendance and revenue reports built in

Built for the people who run the place — not for IT departments
