How Appointment-Based Businesses Do More with Google Calendar

Managing your schedule in Google Calendar is easy. Getting clients to show up to their appointments on time? That's where things break down. Why?

  • Clients ignore or miss pop-up notifications.
  • Google doesn't send SMS or voice call reminders
  • No way to reschedule automatically if a client cancels last minute

Every missed appointment costs you time, revenue, and trust. Apptoto fixes that.

Turn your calendar into a fully automated reminder and scheduling system. Apptoto syncs with your Google Calendar to send SMS, voice, and email messages to any appointment on your schedule. Most tools only send reminders for appointments booked through them. Apptoto sends reminders to appointments made through online bookings, manual entries, phone bookings, CRM syncs, and more.

No more no-shows. No more chasing. Just a calendar that works as hard as you do.

Built for Appointment-Based Businesses Like Yours

Stop struggling with add-ons or workarounds. Apptoto expands Google Calendar into a comprehensive appointment management tool, with booking confirmations, automated appointment reminders, and personalized follow-ups that help keep clients on time and reduce no-shows.

  • Send SMS, voice, and email reminders automatically
  • Allow clients to confirm, cancel, or reschedule with a tap
  • Offer embeddable online scheduling that syncs with real-time availability
  • Add unlimited appointment types to booking pages. Create unique reminders for each.
  • Collect payments, client details, and notes during booking
  • Two-way message clients before and after their appointments
  • Attract more appointments with booking campaigns that entice clients to rebook
  • Stay HIPAA-compliant (if needed)

Set it up once and let it run. Apptoto fits right into your Google Calendar. No switching tools or changing how you work.
