Fitssey Does Everything.
We Do What Matters — Simply.
Fitssey is an impressive platform: branded apps, smart lock integrations, POS systems, auto-cancelling underbooked classes. For large European fitness chains, it's a strong choice. But all those features come with complexity — more setup time, more configuration, more decisions before your first class goes live.
Who's In Studio focuses on what fitness studios actually use every day: class scheduling, waitlists, class packs, memberships, and instructor management. Set up in minutes, not days. Transparent flat pricing, not usage-based tiers. WhatsApp notifications included, not a premium add-on.
🎯 Fitssey: feature-rich for European fitness chains. Who's In Studio: focused simplicity for studios that want to schedule classes, not configure software.
