Apptoto is a powerful platform — but it has no WhatsApp support. For most businesses outside the US, that means reminders going to an inbox nobody checks.

Multi-language reminders
Apptoto sends reminders via SMS, email, and voice — but has no WhatsApp support. In Europe, the Middle East, Latin America, and most of the world, clients check WhatsApp far more than their SMS inbox. Remindly reaches clients where they actually are.
Apptoto starts at $30/month for just 150 message credits — that's $0.20 per message before overages. Remindly's Pro plan gives you 250 reminders for $29/month. And the free plan covers 30 reminders per month with no credit card required.
Apptoto lets clients confirm or cancel. Remindly goes further — when a client wants to reschedule, they reply and get a booking link or a time suggestion automatically. No manual back-and-forth for you.
Apptoto is powerful but complex — built for enterprises with Salesforce, SQL databases, and legal CRM integrations. Remindly is designed for salon owners, coaches, and clinics who want to connect Google Calendar and start sending reminders in minutes.
Remindly is free to start — Apptoto charges from day one
No. Apptoto sends appointment reminders via SMS, email, and voice calls only. WhatsApp is not supported as a native channel. For businesses serving clients in Europe, Latin America, or the Middle East — where WhatsApp is the primary messaging app — this is a significant gap.
Apptoto's base plan is $30/month for 150 message credits, with $0.12 charged per message over the limit. Remindly offers a free plan (30 reminders/month, no credit card) and a Pro plan at $29/month for 250 reminders — more volume at a lower price, including WhatsApp.
Yes. Apptoto is a feature-rich platform designed for enterprises — it has a steeper learning curve. Remindly connects to your Google Calendar in minutes and starts sending reminders automatically. No configuration, no training required.
Yes. If you use Google Calendar, Calendly, Acuity, or Square Appointments, Remindly connects directly. Your existing calendar is unchanged — Remindly reads it and handles the reminders from there.
Yes. Remindly supports automated voice call reminders on the Business plan. If the client does not answer, it automatically retries and falls back to SMS. Voice is available alongside WhatsApp and SMS — not instead of them.
Connect your Google Calendar and start sending WhatsApp reminders in minutes. Free plan available — no credit card required.
