Why it works
One of these you ignore.
The other you act on.
Full-screen alarm
A real alarm, full-screen on the lock screen. Goes through Silent, DND, and Focus modes. You can't miss it — and that's the point.

Why Callendar
Notifications get ignored. Alarms don't.
Callendar puts a real alarm on every meeting — the one reminder your phone isn't allowed to quiet.
Rings like a real alarm
A full-screen alarm on iPhone and Android. It wakes the device, rings over silent mode, and puts Dismiss and Open on the lock screen.
Rings when your phone is silent
Silent-mode notifications are why people miss meetings. An alarm is different — your phone rings for it regardless of Silent, Do Not Disturb, or Focus.
Syncs with Google Calendar
Connect any number of calendar accounts on Pro. Callendar reads upcoming events and schedules an alarm for each one. Quiet hours and weekend toggles are respected.
Join in one tap
Tap Open and the meeting URL is already loaded. Zoom, Google Meet, Teams — one tap puts you in the room. No more "hold on, let me find the link."
Pick your alarm ringtone
Classic, gentle, urgent, office, melody — or vibration only. Set a default, override it per event, and set how loud it rings.
Two alarms, one meeting
Set a 10-minute heads-up and a final 2-minute alarm. Every reminder time you pick arms its own alarm, so the second one still goes off.
How it works
Three steps. Two minutes.
Connect your calendar
Sign in with Google. Callendar reads your meetings — nothing else. Read-only, revocable any time.
Pick your alarm ringtone
Classic, gentle, urgent, office, melody — or vibration only. Set global defaults, then override per meeting.
The alarm goes off
Minutes before each meeting, a full-screen alarm goes off. Works on silent, needs no signal, survives a reboot.
Professionals who stopped missing meetings
Real users. Real alarms going off.
“I used to miss a meeting a week because my phone was on silent. Callendar sets a real alarm and Silent mode doesn't get a say — I haven't been late to a standup since.”
“Back-to-back calls all day, and my phone stays on Do Not Disturb. Callendar goes off anyway, and the meeting link is already loaded when I open it.”
“A full-screen alarm on the lock screen is exactly what I needed. Silent notifications are invisible to me — an alarm going off isn't.”

Common Questions Answered
Quick answers to the questions people ask most about Callendar.
Does the alarm really ring when my phone is on silent?
Yes. Callendar schedules a real alarm, and your phone treats an alarm differently from a notification — full-screen on the lock screen, ringing over silent mode and through Focus. On Android, a full-screen alarm wakes the device and rings over silent mode.
Will Callendar ring during Focus mode or Do Not Disturb?
Yes. Callendar schedules a real alarm, and alarms are allowed through Focus and Do Not Disturb by default — the same way your wake-up alarm is. You stay in control: quiet hours, per-event overrides, and volume are all yours to set.
What's the best meeting reminder app for iPhone?
Callendar is purpose-built for iPhone. On iOS 26 and later it schedules a real system alarm for every meeting — full-screen on the lock screen, through Silent and Focus, and it still fires with no signal or after a reboot. On earlier versions you get a full-screen ring instead.
Can Callendar remind me about Google Meet and Microsoft Teams meetings?
Yes. Callendar reads your Google Calendar events, which include the video conference links embedded in meeting invites. When the alarm goes off, the Zoom, Google Meet, or Teams URL is already loaded — one tap joins the meeting.
What is a full-screen alarm and why does it matter for meeting reminders?
A full-screen alarm takes over the whole screen, on the lock screen, and rings out loud. Your phone is allowed to hold a notification back — Silent, Do Not Disturb and Focus all get a say — but an alarm is something you asked for, so it goes through. Callendar schedules a real alarm for every meeting so your reminder can't be filtered out.
How is Callendar different from regular calendar notification alerts?
Standard calendar alerts appear as small banner notifications that disappear in seconds and are completely silent if your phone is on mute. Callendar replaces the banner with a full-screen alarm — it lights up your screen, rings over silent mode, and puts the meeting one tap away.
