- What is Callendar?
- Callendar is a meeting reminder that rings your phone like an incoming call before every meeting. Silent notifications get dismissed in a glance — a full-screen call doesn't. Syncs with Google Calendar and Outlook, works on iOS and Android.
- How much does it cost?
- Callendar is free to use with one calendar and the default ringtone. Pro unlocks unlimited calendars, custom ringtones, smart quiet hours, auto-answer, and Meeting DNA stats for $5.99/month or $59.99/year (about $4.99/month billed annually).
- What platforms is Callendar available on?
- Callendar is a native iOS app (iOS 15+) and a native Android app (Android 8+). It rings via CallKit on iPhone and a full-screen call activity on Android, so it breaks through silent, Do Not Disturb, and Focus modes.
- Which calendars does it support?
- Google Calendar and Microsoft Outlook. You can connect any number of accounts on Pro — personal, work, and shared calendars — and Callendar schedules a ring for each upcoming event.
- 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.
- Is my data secure?
- Yes. Callendar requests read-only access to your calendars — we read upcoming events to schedule rings and nothing else. Your calendar data is never sold, and your events are not used to train any models.
- Can I pick my ringtone?
- On Pro you can choose from classic phone ring, gentle, urgent, office, melody — or vibration only. Set a global default and override it per calendar so work meetings and personal events can sound different.
- How do I cancel my subscription?
- You can cancel your Pro subscription at any time from your device's App Store or Google Play subscription settings. Your access to Pro features continues until the end of your current billing period, and you won't be charged again after cancellation.
- Do you offer team or business plans?
- We're exploring team plans with admin controls and centralized billing. Contact us at info@clutchdeveloper.com to get early access and share your team's requirements.
- How do I stop missing Zoom calls?
- The most common reason people miss Zoom calls is that standard notifications are easy to overlook — especially on a silent phone. Callendar delivers a full-screen incoming call, just like a regular phone call, minutes before your Zoom meeting starts. Answer it and you're one tap away from joining.
- 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.
- What's the best meeting reminder app for Android?
- Callendar for Android presents a full-screen incoming-call activity that wakes your device and rings over silent mode, powered by a high-priority background service. It's the closest you can get to a real phone call reminder on Android.
- 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.
- How do I make my phone ring for meetings automatically?
- Install Callendar, connect your Google Calendar or Outlook account, and choose your ringtone. Callendar does the rest — it reads your upcoming meetings and schedules a phone-call-style ring automatically for each event, with no manual input required.
- Does Callendar work if my phone reboots?
- Yes. Callendar uses server-side scheduling to fire a push notification at the right time. Even if your phone restarts between now and your meeting, the ring will still arrive because it originates from our servers, not a local timer on the device.
- Is there a wake-up-call style reminder for early morning meetings?
- Callendar can ring for any calendar event — including early morning meetings. Configure quiet hours in the app if you don't want late-night rings, and Callendar will respect those boundaries while still waking you for your 7 a.m. standup.
- 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.
- Can I set a different reminder time, like 5 minutes or 1 minute before the meeting?
- Yes. Callendar supports configurable lead times so you can choose when the first and second reminder fire — for example, 10 minutes and 2 minutes before, or 5 minutes and 1 minute before. Pro users can also customize this per calendar or per event type.
