TimeRex

What TimeRex is
TimeRex is a web scheduling service that finds meeting times and registers appointments through Google Calendar or Outlook. An organizer shares a scheduling-page URL, letting invitees choose an available date and time. Calendar synchronization works in both directions, and the service supports group bookings, round-robin routing, cancellations, rescheduling, and reminder emails. It can create meeting URLs through Zoom, Microsoft Teams, and Google Meet integrations. Team scheduling can consider multiple people, although the Free plan covers up to two schedules. That plan costs nothing forever and includes unlimited calendars and bookings. Listed Free integrations include Slack and Microsoft Teams Chat notifications, Google Sheets, Zapier, and webhooks. Premium lists Salesforce, HubSpot, Google Analytics, Google Ads, and Facebook Ads. TimeRex requires a Google or Microsoft account, offers email and chat support, and describes SSL/TLS encryption and ISO 27001 information-security management.
