GReminders

GReminders is an appointment-scheduling and reminder tool built to layer directly onto the calendars businesses already use — Google Calendar, Outlook, and Office 365 — rather than replace them. You keep booking inside your familiar calendar while GReminders adds the missing pieces: shareable scheduling pages and automated reminders that cut no-shows.

Its standout is reminder flexibility: automated SMS, email, and even voice reminders to clients, with customizable timing and messaging. Recipients can confirm, cancel, or reschedule straight from a reminder, and those changes sync back to your calendar automatically. On top of that it offers online booking pages, availability management, and integrations with CRM systems like Salesforce and HubSpot, making it a fit for teams that want scheduling plus dependable client notifications in one place.

Pricing is freemium: a free Basic plan covers the essentials, and the paid Standard plan starts at about $8 per user per month, with higher tiers adding advanced features and integrations. GReminders is web-based and works through your existing Google or Microsoft calendar. It fits small and mid-size businesses — especially appointment-heavy ones like clinics and advisors — that want strong reminder automation attached to simple scheduling.
