Stop Fighting With Overcomplicated Booking Software
You signed up for a booking system once. Spent an afternoon setting it up. Clients still booked randomly by text, call, or just walked in. Sound familiar?

More than just reminders
The most complete SMS reminder app for Google Calendar — with one-tap cancellations, automated review requests, AI-powered contact matching, and group messaging built in.
Calendar event → SMS sent
Create an appointment in Google Calendar. Your client gets SMS reminders automatically — no extra steps.
Quiet hours & smart timing
Reminders respect quiet hours and time zones. Late-night bookings get rescheduled to morning — your clients are never disturbed.
One-tap cancellation
Clients cancel via a link in the SMS. The calendar event is removed and you get an email — no phone tag needed.
Automated review requests
After appointments, clients can receive a neutral review prompt with your Google review link where enabled.
Smart contact matching
Etisia reads the event title, finds the matching contact, and gets the phone number — even if the name isn't written perfectly.
Group messaging from events
Select calendar events, pull the recipients, add extras manually. One click sends personalized SMS to everyone — with dedup and opt-out safety.
Simple plans for small and midsize service businesses that don't want another complicated booking system
Keep Google Calendar as the main calendar your team works from. Etisia adds reminders, review requests, and one-tap cancellations without a new booking system or workflow builder.

Zero risk
Still have questions?
Is Etisia a booking system?
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, client confirmations or cancellations, and an updated Google Calendar.
Why not use regular booking software?
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.
How is Etisia different from basic reminders?
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, cancellations, confirmations, 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.
How reliable are Etisia reminders?
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.
What is smart monitoring?
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."
Do clients need to install anything?
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.
What if clients book by phone, text, WhatsApp, or in person?
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.
Can clients confirm or cancel by SMS?
Yes.
You can include confirmation and cancellation options in the reminder, so clients can respond before the appointment instead of forgetting, cancelling too late, or simply not showing up.
That gives you a better chance to protect the slot.
Do I need to migrate my appointments?
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.
Do I need a credit card?
No.
Create an account, connect Google Calendar, and try Etisia on your own appointments.
Free SMS credits are included, so you can see the reminder flow before deciding.
