RINGING…
Team Standup
Meeting at 10:00 · Google Meet
Starts in 2:04
Why it works
One of these you ignore.
The other you answer.
Silent notification
Buried under 40 others. Read in 0.3 seconds, dismissed in 0.4. Your phone on silent? It never showed up at all.
Calendar
Team Standup in 2 min
→ You look up. The meeting started 7 minutes ago.
Incoming phone call
Full-screen ring like your mom calling. Breaks through silent, DND, and focus modes. You can't miss it — and that's the point.

Why Callendar
Notifications get ignored.
Calls don't.
Callendar turns every meeting into an incoming call — the only reminder your brain still respects.
Rings like a real phone call
Full-screen CallKit on iOS, full-screen activity on Android. Wakes the device, breaks through silent mode, and feels exactly like your mom calling.
Works when your phone is silent
Silent-mode notifications are why people miss meetings. VoIP push breaks through — your phone wakes for a call regardless of DND, silent, or focus mode.
Syncs Google Calendar & Outlook
Connect any number of calendar accounts. Callendar reads upcoming events and schedules a ring for each one. Quiet hours and weekend toggles are respected.
Join in one tap
Answer the call 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 ringtone
Classic phone ring, gentle, urgent, office, melody — or vibration only. Set a default and override it per event.
Two reminders, one meeting
Get a 10-minute heads-up then a final 2-minute ring. Answer the first and the second stays silent. Miss it and the backup fires.
How it works
Three steps. Two minutes.
Connect your calendar
Sign in with Google Calendar or Outlook. Callendar reads your meetings — nothing else. Read-only, revocable any time.
Pick your ringtone
Classic phone ring, gentle, urgent, office, melody — or vibration only. Set global defaults, then override per meeting.
Get called
Minutes before each meeting, your phone rings like a real call. Full-screen on lock screen, works on silent, survives reboot.
Professionals who stopped missing meetings
Real users. Real phones ringing.
“I used to miss at least one meeting a week because my phone was on silent. Callendar calls me like my mom would — I haven't been late to a standup since.”
Sarah Chen
Product Manager
“Back-to-back calls all day, and my phone stays on Do Not Disturb. Callendar breaks through every time, and the meeting link is already loaded when I answer.”
David Miller
Sales Lead
“Full-screen ring on the lock screen is exactly what I needed. Silent notifications are invisible to me — an incoming call isn't.”

Dažniausiai užduodami klausimai atsakyti
Greiti atsakymai į dažniausiai užduodamus klausimus apie Callendar.
- Does it really ring when my phone is on silent?
- Yes. On iOS, Callendar uses VoIP push and CallKit, so the system treats it as a phone call — full-screen ring on the lock screen, breaks through silent and Focus modes. On Android, a full-screen incoming-call activity wakes the device with the same behavior.
- Will Callendar ring during Focus mode or Do Not Disturb?
- Yes. On iOS, Callendar uses Apple's VoIP push framework — the same channel real phone calls use — which is allowed to break through Focus and Do Not Disturb by default. You stay in control: you can configure your Focus mode to allow Callendar calls if needed.
- What's the best meeting reminder app for iPhone?
- Callendar is purpose-built for iPhone using CallKit, Apple's native call interface. It delivers a full-screen lock-screen ring for every meeting — identical to an incoming phone call — making it the most attention-demanding meeting reminder available on iOS.
- Can Callendar remind me about Google Meet and Microsoft Teams meetings?
- Yes. Callendar reads your Google Calendar and Outlook events, which include the video conference links embedded in meeting invites. When you answer the Callendar call, the Zoom, Google Meet, or Teams URL is already loaded — one tap joins the meeting.
- What is CallKit and why does it matter for meeting reminders?
- CallKit is Apple's framework that lets apps display their notifications as a native incoming phone call on iOS — full-screen, on the lock screen, with the green and red answer/decline buttons. Because the system treats it like a real call, it bypasses silent mode and Focus. Callendar uses CallKit specifically so your meeting reminder can't be ignored.
- 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 ringing call — it lights up your screen, makes noise, and stays on screen until you act on it. There's no comparison.
