A complete toolkit for appointment-based businesses — from booking to billing, all in one place.
A beautiful full-screen calendar powered by FullCalendar. Create, move and manage appointments with drag & drop. Colour-coded statuses — scheduled, confirmed, completed, cancelled — let you see your day at a glance.
Build and maintain full client profiles including contact details, preferred communication language and notes. Browse a complete history of every appointment and every SMS message sent — right from the client's profile page.
Write personalised reminder messages using smart variables:
{client_name}, {service_name}, {appointment_date},
{appointment_time}, {business_name}.
Create multiple templates and set one as default — RemindersOS handles the rest.
Set reminders to fire at exactly the right moment — 24 hours before, 1 hour before, or any custom interval you define. Multiple reminder rules can run per appointment so clients never forget.
Understand your business at a glance. Track SMS delivery rates, appointment trends over time, credit consumption, and more. Export data for your records or share with your team.
Pay-as-you-go SMS credits mean you only pay for what you actually send. Top up via Stripe or PayPal in seconds. View a full transaction history and set low-balance alerts so you're never caught short.
