Clear answers

A few things worth knowing.

Android gives you powerful control over alarms. We help make the setup understandable.

Visit the complete FAQ
01How does Calendar Alarm work with my existing calendar?

Calendar Alarm reads the calendars you choose on Android and can also connect supported Google, Microsoft Outlook, and CalDAV accounts. It brings events into one view and lets you turn selected events or calendars into persistent alarms.

02Does every calendar event have to trigger an alarm?

No. You can enable or mute alarms by calendar and adjust individual events. That makes shared, holiday, or informational calendars useful without making them noisy.

03Can I choose the sound, volume, and snooze time?

Yes. Calendar Alarm supports custom alarm sounds, volume behavior, vibration, and flexible snooze timing. Some choices depend on your Android version and device permissions.

04Why does the app ask about battery optimization?

Some Android manufacturers restrict apps in the background. Allowing Calendar Alarm to run reliably helps it schedule and present alarms at the intended time. The in-app troubleshooting guide explains the settings for common devices.

05Is Calendar Alarm an ADHD treatment?

No. It is a calendar and reminder tool, not a medical device. Some reviewers with ADHD or time blindness say persistent alarms help them notice appointments, but experiences vary.
