Loved by instructors and academy owners

Real feedback from academies that switched to OSS Manager.

“Before OSS Manager, I managed my academy using the notes app on my phone. Today, I save many hours every week and have a much broader view of my business—especially when it comes to payment management. What made me switch was the need to professionalize my academy, and the personalized support made all the difference. Since I started using OSS Manager, the number of students has doubled. If a fellow instructor were unsure, I would say: your students deserve an app that provides all the features every academy should have.”

Frequently asked questions

Everything an academy owner wants to know before switching.

Full access to every feature — students, attendance, graduation, gamification, and payment collection — for 15 days. No credit card required, and you can cancel anytime during the trial.
No — we help with the entire migration. Our team supports you through every step of importing your students, plans, and history from your current system.
Students pay via Stripe (card, worldwide) or, for Portuguese academies, also via EasyPay (MB WAY, SEPA Direct Debit, Multibanco). Charges run automatically on the contract's schedule, with reminders before due dates and overdue alerts — you don't have to chase anyone manually. A 1% platform fee applies to charges collected via Stripe Connect, on top of Stripe's standard processing fees.
Yes. Each martial art has its own belt/graduation system, classes, and student progression tracked independently — a student practicing two arts has separate belts, XP, and streaks for each.
We're available on Web, iOS, and Android, and everything is designed to be simple — students who use it enjoy it, and most pick it up without any training.
No lock-in — you can cancel whenever you want.
No limits — you can have as many students and teachers as you want.
You can request support directly through our WhatsApp channel.
