Callendar

Schedule Meetings with Your WhatsApp Contacts.
Callendar is your all-in-one solution for scheduling and managing meetings. Callendar is natively integrated with WhatsApp, enabling you to schedule meetings with WhatsApp contacts, send seamless WhatsApp reminders, and manage automatic rescheduling—all without leaving WhatsApp. Everything is managed in one place, directly within the app.
Your invitees receive a WhatsApp reminder one day before and a few minutes before the meeting. The notification includes options to cancel or reschedule the meeting on their own.

No-shows are significantly reduced, and you no longer need to send manual reminders or respond to WhatsApp messages around the clock. Stay focused on your business while Callendar handles your meeting reminders and more.

Callendar App is free to use and includes up to 10 WhatsApp reminders per month. Please note that WhatsApp notifications are provided by Meta as a paid service. While we offer a free quota, exceeding it may incur additional costs from Meta.
