The most complete SMS reminder app for Google Calendar - with one-tap cancellations, AI-powered contact matching, and group messaging built in.
Create an appointment in Google Calendar. Your client gets SMS reminders automatically - no extra steps.
Reminders respect quiet hours and time zones. Late-night bookings get rescheduled to morning - your clients are never disturbed.
Turn on the cancellation link and clients can cancel straight from the SMS. The calendar event is removed and you get an email - no phone tag needed.
Etisia reads the event title, finds the matching contact, and gets the phone number - even if the name isn't written perfectly.
Select calendar events, pull the recipients, add extras manually. One click sends personalized SMS to everyone - with dedup and opt-out safety.
You do not need a booking system, and your clients do not need to change how they book.
Connect it and keep working exactly as you do today. Etisia handles the SMS reminders in the background.
No migration. No new workflow.
Start with one simple Google Calendar. Clients can still book by phone, message, or in person-you add the appointment once, and Etisia handles the reminder.
A simple first step into digital scheduling.

No - and that is the point.
Etisia does not try to replace the way clients book with you. They can still call, text, use WhatsApp, email, walk in, or book in person.
Etisia focuses on what happens after the appointment exists: reliable SMS reminders, secure cancellation links, and an updated Google Calendar.
Because booking software often forces you to rebuild how you work before it solves the actual problem.
You create services. Set hours. Add a team. Configure rules. Build a booking page. Teach clients to use the link.
Then real life happens: clients still call, text, use WhatsApp, and book in person. Etisia works with that reality. You add the appointment to Google Calendar and the reminder runs automatically.
Basic reminders are usually just an add-on.
Etisia is built around reminders as the core product: SMS timing, calendar detection, contact handling, reminder status, secure cancellation links, opt-outs, and follow-up messages are part of the same reminder flow.
You do not get a booking system with reminders bolted on. You get a reminder system built specifically to help clients show up.
Etisia is designed to keep reminders as reliable and timely as possible.
The system watches upcoming reminders, checks status, flags missing phone numbers, detects opt-outs, and helps prevent silent sending failures. The demo shows this through event statuses such as SMS ready, SMS sent, no SMS, opt-out, and missed reminder windows.
The goal is simple: once the appointment is in your calendar, you do not have to wonder whether the reminder will actually go out.
Smart monitoring means Etisia does not just "send an SMS and hope."
It tracks the reminder flow around each appointment. If a phone number is missing, the client opted out, the reminder window has already passed, or something needs attention, Etisia shows it instead of hiding it in another dashboard.
That is the difference between "we send SMS" and "we help you run reminders properly."
No.
Clients receive a normal SMS. No app. No login. No client portal. No new behavior to learn.
That matters because the whole point is to avoid forcing clients into systems they may never use.
Perfect. That is exactly what Etisia is made for.
Your clients can keep booking the way they already reach you. You just add the appointment to Google Calendar, and Etisia handles the reminder from there.
It does not matter where the booking came from. The calendar event is what triggers the reminder.
No. Etisia does not provide two-way SMS conversations.
Clients cannot confirm, cancel, reschedule, or ask questions by replying to the SMS. Where supported, keywords such as STOP are handled only as opt-outs.
A reminder can include a secure cancellation link. Etisia is a reminder layer for Google Calendar, not a support inbox or client portal.
No.
Google Calendar stays the simple place where your appointments live. Etisia adds a reminder layer around it, so you do not have to migrate into a full booking platform or manage another scheduling dashboard.
Your team keeps the calendar workflow it already knows.
No.
Create an account, connect Google Calendar, and try Etisia on your own appointments.
