As a small business owner and software developer, I am insanely busy. I've completed my own testing of this app and it does exactly what it says it does. I am so impressed that I will be subscribing to the paid version.

This app is amazing! It syncs seamlessly with Google Calendar and sends automatic text message reminders. The setup is fast and easy, even for people who aren't very tech-oriented. I haven't missed a single appointment since.

Worth the math

What does a no-show actually cost you?

A single missed appointment is rarely just one lost slot — it's the time, the prep, and the opportunity to book someone else. Even recovering a handful of no-shows each month is typically enough to cover the cost of SMS Reminder several times over.

Adjust the numbers on the right to see what automated reminders could mean for your bottom line.

Plans starting from $19/month USD — cancel any time.
