What is Callendar?
Callendar syncs Google Calendar meetings and provides reminders on iPhone and Android. Premium adds call-style alarms on supported devices. These alerts do not place a carrier phone call.
How much does it cost?
The free plan includes one Google account and basic reminder options. Premium adds full-screen alarms on supported devices, more reminder choices, multiple accounts, and customization. Listed US prices are $4.99/month or $39.99/year. Your store shows local pricing and any eligible 7-day trial before purchase.
What platforms is Callendar available on?
Callendar is available for iPhone and Android. Check your store listing for device compatibility. Alert presentation depends on the operating-system version, permissions, and settings.
Which calendars does it support?
Callendar syncs each connected Google account’s primary calendar. Premium supports multiple accounts. Shared and secondary calendars and Outlook sync are not supported.
Does the alarm really ring when my phone is on silent?
It depends on your device, alarm permissions, and sound settings. Alarm-style reminders differ from standard notifications. Run a free test with your normal settings to confirm what you hear and see.
Is my data secure?
Callendar requests read-only access to supported Google Calendar events to provide reminders. You can revoke access from your Google account. See our privacy policy for details about data processing and retention.
Can I pick my alarm ringtone?
Yes. Free includes the Classic and Gentle ringtones. Pro adds urgent, office, melody — or vibration only, plus alarm volume control. Set a global default and override it per event 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?
Confirm your Zoom link is in a synced Google Calendar event, enable the reminder, and choose a useful lead time. Run a test alert and open the event’s supported meeting link when available.
Will Callendar ring during Focus mode or Do Not Disturb?
Behavior varies with your device, operating system, permissions, and quiet-mode settings. Test the alert with Focus or Do Not Disturb enabled as you normally use it, and review Callendar’s quiet hours.
What's the best meeting reminder app for iPhone?
If you want call-style Google Calendar reminders on iPhone, you can test Callendar before subscribing. Check device compatibility, alarm authorization, reminder timing, and how the alert behaves with your settings.
What's the best meeting reminder app for Android?
Callendar offers Google Calendar reminders on Android, with call-style alarms through Premium on supported devices. Check notification, exact-alarm, and full-screen permissions and run a free test.
Can Callendar remind me about Google Meet and Microsoft Teams meetings?
Callendar can detect supported Google Meet, Teams, and Zoom links in synced Google Calendar event details and open them. These are event links, not separate calendar integrations.
How do I make my phone ring for meetings automatically?
Connect your Google account, confirm the event appears, enable reminders, and choose from the lead times available to your plan. Grant the required permissions and test an alert before relying on it.
Does Callendar work if my phone reboots?
Device restarts, force-stopping an app, and system settings can affect reminder behavior. After restarting or changing settings, reopen Callendar, check sync and permissions, and test a reminder. A connection is needed to fetch calendar updates.
Is there a wake-up alarm for early morning meetings?
You can enable reminders for eligible early-morning events. Check lead times and quiet hours so they match your schedule, and test with the phone settings you use overnight.
What is a full-screen alarm and why does it matter for meeting reminders?
A full-screen alarm is a prominent alert that can display meeting information and controls. Callendar offers call-style alarms with Premium on supported devices; permission, operating-system, and sound settings affect how they appear.
How is Callendar different from regular calendar notification alerts?
Standard calendar notifications and call-style alarms use different system features. Callendar adds reminder timing and a more prominent alert option with Premium. Test both with your device settings to choose what suits you.
Can I set a different reminder time, like 5 minutes or 1 minute before the meeting?
Yes. Choose from the reminder lead times available to your plan. Premium adds more timing choices and per-event settings. Check the options in the app and test your selected reminders.
