In their own words
ClassWolf
ClassWolf is a multi-tenant cloud platform for schools that run recurring activities such as dance, yoga, fitness, martial arts, music and languages. It generates course sessions on a calendar and keeps them synchronized when the source course changes. Staff can record attendance as present, absent, late or excused, add walk-ins and save entries automatically. Public course pages provide branded enrollment links, seat counts and waitlists, with automatic promotion and confirmation emails. Schools can offer class packs, time-based passes and unlimited memberships, with expiry dates and remaining balances visible. Teacher earnings can be calculated from fixed fees or percentages of collected fees and exported in monthly reports. Collections can be sent to existing invoicing software such as Holded; Verifactu and SDI integrations are listed for Pro. The staff app and automated emails are available in English, Spanish, Italian, French and German. Customer data is hosted on EU-based infrastructure and can be exported at any time. The free Cub plan allows up to 3 courses, 3 disciplines, 3 teachers and 30 students, but excludes fee collection, reports, communications and online payments. Starter costs €99 a month; Pro costs €149 a month.
