SMS Reminder for Google Calendar™, now Kalama, sends automatic SMS appointment reminders from the Google Calendar™ you already use, lets clients confirm or cancel by replying to the text, and gives you a free online booking page with your own logo and brand colour. Google Calendar™ stays your source of truth, so there's no new calendar to manage. Built for salons, trainers, tutors, mobile services and small teams who run on appointments.

Free to start, no credit card
- A free online booking page on your primary Google Calendar™, forever
- Your logo and brand colour on the page, free on every plan
- Unlimited appointment types
- 25 SMS reminders to try (one time, they don't expire)
- Paid plans from $19/month USD add monthly reminders, more calendars and more users. No features held back on any plan.

Why businesses choose SMS Reminder
- Less setup for every appointment. Bookings from your booking page get reminders automatically. For appointments you add yourself, open the event, add the client's number from the sidebar and save. In the web app, approve a suggested number once and future appointments with it, including recurring ones, switch on by themselves.
- Clients just text back. "Yes" or 👍 confirms. "Can't make it" cancels and frees the slot. Asking to move? They get your booking link.
- Your calendar updates itself. Events turn green (confirmed), yellow (pending) or red (cancelled), with the status in the title. Cancelled appointments stop getting reminders.
- A booking page that looks like your business. Your logo and colour on every booking page and on the booking button for your website. Clients book, reschedule or cancel themselves. Add booking questions, buffers and notice periods, and a location or Google Meet™ link for each service.
- A cancellation policy that works for you. Set a notice window, warn or block late cancels, and see every late cancel in one list so you can follow up or charge your fee.
- Every message, your way. Unlimited templates for confirmations, reminders and follow-ups, filled in with the appointment's date, time, location and video call link (Google Meet™, Zoom, Microsoft Teams or Webex).
- Lives in Google Calendar™. Open it from the right-hand sidebar. Nothing new to learn.
