Kronoz

Kronoz is a shared calendar for service providers and their clients — built for personal trainers, coaches, tutors, and anyone who books people into recurring sessions. Providers publish their availability once. Clients join with a single invite code, see exactly what's open, and book in seconds. No group chats, no spreadsheets, no back-and-forth over text. FOR PROVIDERS — Publish recurring and one-off availability by session type, duration, and capacity — Share one invite code or QR for every client to join — no per-client invites to manage — See bookings and cancellations update live, right from your week view — Get push notified the moment a client books, cancels, or joins — Manage a waitlist automatically — when a spot opens up, the next person in line is booked in instantly — Lock the app with Face ID, Touch ID, or fingerprint to keep your calendar private FOR CLIENTS — Join a provider's calendar with one code or QR scan — nothing else to sign up for — See only that provider's real availability, not a generic booking form — Book instantly, and join a waitlist when a session is full — Track sessions across every provider you've joined, all in one place — Free to use, always Kronoz keeps scheduling out of your messages and into one place both sides can see.
