How to Get a Phone Call Reminder from Your Android Calendar

Android's calendar apps — whether you use Google Calendar, Samsung Calendar, or another OEM variant — send push notifications when a meeting is about to start. These notifications work fine when your phone is in your hand. But if your screen is off, your phone is in your pocket, or you're focused on something else, that notification disappears in seconds. An outbound phone call doesn't disappear. Your Android phone rings until you answer.

This guide explains how to add real phone call reminders to any Android calendar, using Remindavo. It reads your calendar events and places an outbound call to your phone before each one. Setup takes under 60 seconds.

Why Android Calendar Notifications Fall Short

Google Calendar on Android offers several reminder types: notifications, emails, and custom alert sounds. These are all passive — they appear on-screen and wait to be acknowledged. The core problem is that they require you to see your phone at exactly the right moment.

Android also has Do Not Disturb and Focus Mode settings that can silence notifications entirely during meetings or focused work — which means the reminder you set for your next meeting might be blocked by the very mode you activated for the current one. A phone call behaves differently: it rings your actual phone hardware and, with the right contact settings, can break through DND.

Reminder type	Works off-screen	Bypasses Do Not Disturb	Hard to miss
Android push notification	No	No	Easy to miss
Google Calendar email reminder	No	No	Buried in inbox
Android alarm	Yes	Sometimes	Easily dismissed
Phone call (Remindavo)	Yes	Yes (with contact settings)	Very hard to ignore

How Remindavo Works with Android Calendars

Remindavo connects to your Google Calendar account via standard OAuth. On Android, Google Calendar is the backbone of most calendar apps — whether you're using Google Calendar directly, Samsung Calendar synced with Google, or any other app that reads from your Google account. All events from these apps flow through the same Google Calendar API.

Once connected, Remindavo reads your upcoming events and places an outbound call to your registered phone number before each one — your Android rings with a reminder. You pick up, hear a brief voice reminder with the event name and start time, and you have time to prepare. The whole call takes about 10 seconds.

Which Android Calendars Are Supported?

Remindavo works with any calendar that syncs through Google Calendar or Microsoft Outlook:

• Google Calendar — the default Android calendar on most devices. Fully supported.
• Samsung Calendar — syncs with Google Calendar automatically on Samsung Galaxy devices. Covered through the Google Calendar connection.
• Work calendars (Google Workspace) — connect your work Google account during setup and meetings from your work calendar get call reminders too.
• Microsoft 365 / Outlook — Remindavo also supports Microsoft Outlook OAuth. If your work calendar runs on Exchange or Microsoft 365, connect your Microsoft account instead.
• Any third-party Android calendar app that syncs to Google Calendar — works automatically once your Google account is connected.

Setup Guide (Under 60 Seconds)

1. Create your Remindavo account Go to app.remindavo.com on your Android browser or any device and sign up with your Google or Microsoft account. The 14-day trial is free — no credit card required.
2. Connect your Google Calendar Authorize Remindavo via standard Google OAuth. It reads your event titles and times but never modifies your calendar or stores event content. This covers all events visible in your Android Google Calendar app.
3. Add your phone number Enter your Android phone number — the one you want ringing before your meetings. Remindavo sends a test call immediately so you can confirm it's working before your next event.
4. Set your lead time Choose how many minutes before each event you want the call — 2 minutes before for a quick heads-up, or 30 minutes ahead if you need preparation time.
5. You're done Remindavo runs in the background. Before every event in your connected Android calendar — meetings, client calls, appointments, anything — your phone rings. No app to check, no per-event setup needed.

Getting Calls Through Android Do Not Disturb

Android's Do Not Disturb mode can block incoming calls. To make sure Remindavo's reminder calls always get through:

• Save Remindavo's caller number to your Android contacts (you'll see it after the test call)
• Open Settings → Notifications → Do Not Disturb → Exceptions → Calls
• Set it to allow calls from All contacts or Starred contacts, then star the Remindavo contact

On Samsung Galaxy devices, the path may be Settings → Sound and vibration → Do Not Disturb → Allowed exceptions. The exact path varies slightly by Android version and manufacturer, but the setting exists on every modern Android device.

Works for Every Calendar Event Type

Remindavo reads your entire calendar, not just specific meeting types. You get a call before:

• Google Meet, Zoom, Teams, or Webex meetings added to your Google Calendar
• Client calls and one-on-one appointments with specific start times
• Recurring events — weekly standups, regular check-ins, team meetings
• Medical and healthcare appointments
• Interviews and time-critical professional calls
• Personal calendar events you never want to miss
• Any meeting invite accepted from a colleague or client

If it's on your Android calendar, Remindavo will call you before it.

Common Questions

Android is designed around notifications, but notifications are passive — and passive reminders fail when you're busy. A phone call is a completely different category of alert: it demands your attention and doesn't disappear until you acknowledge it. For meetings that matter, it's the most reliable way to ensure your Android calendar actually gets you there on time.
