Every appointment,
in its place
ndna calendar is online booking for specialists. Clients pick a service and a free time on your booking page; the booking lands in your calendar, and both of you get an invite and reminders.
What it does
Your own booking page
Services with a length, a price and a place: in person, by phone, a meeting link or Google Meet.
Working hours
Set when you work, buffers between appointments, minimum notice and how far ahead clients can book.
Calendar sync
Connect Google Calendar: busy times block slots on your booking page, and every booking is added to your calendar. Microsoft Outlook and Teams coming soon.
Invites and reminders
You and your clients get an email invite to add to Google Calendar, Outlook or Apple Calendar, and a reminder before the appointment.
Easy rescheduling
Move or cancel a booking from the app and your client is told; clients cancel from their own private link.
AI assistant
Ask the built-in assistant, or your own AI tool over MCP, about your bookings and free times.
Your calendar stays yours
Connecting a calendar is optional. ndna calendar reads your busy times from Google Calendar so clients only book when you are free, shows your events next to your bookings, and only adds, moves or removes the events it created for them. Your data is never sold or used for ads, and you can disconnect at any time. More in our Privacy Policy.
