FitOS is the open-source coaching operating system. Deploy your own instance. Use Google Sheets as your database. Let AI agents handle the busywork. Pay once, own it forever.
No proprietary formats. No vendor lock-in. Every client gets a Sheet in your own Drive. Apps Script handles automation. You see everything, own everything, control everything.
Every piece runs on infrastructure you control. No middleman between you and your clients.
Per-client spreadsheets with workout tabs, check-in forms, progress dashboards, and exercise libraries. The schema is code. The data is yours.
onEdit triggers fire webhooks when clients log sets. Check-in submissions stream to your dashboard in real-time. No polling. No delays.
Claude-powered skills analyze check-ins, suggest progressive overload, flag RPE drift, and draft weekly summaries. You approve, the agent executes.
Installable, offline-first, push-notification-capable. Photo and video uploads via Drive. Native-feeling performance. Competes with TrueCoach's app.
Two spreadsheets per client. Coach notes are invisible to clients by Drive permissions, not hidden tabs. Real privacy, not security theater.
Monthly skill drops via the FitOS School. New agent capabilities without dashboard rewrites. Modular, versioned, declarative.
Every coaching platform charges you more as you grow. FitOS charges you once.
$497 lifetime license. $97/mo school for continuous skill updates. Your infrastructure. Your clients. Your data. No one can take it away.
