Everything You Need to Scale Your Training Business
FitOS combines powerful coaching tools, built-in CRM, and AI-powered featuresβall in one platform. No more juggling multiple apps or paying per-client fees.
Tired of Glitchy Apps That Make Your Business Look Bad?
Unreliable Platforms
"Trainerize is far too glitchy... made me feel like it was diminishing the quality of my business."
Hidden Costs
Per-client fees that eat into your revenue. $350/month just for unlimited clients? That's your profit margin.
Limited Mobile Editing
Most platforms only let you view on mobile. Need to edit a workout? Good luck doing that from the gym floor.
Clinical, Outdated Design
"Too clinical" interfaces that require training videos for everything. Your clients deserve better.
