Events
Notification sound, vibration & LED
Choose the ringtone for event reminders and configure vibration and LED. On Android 8 and above you can also access the Android notification channel settings directly from here.
Snooze duration
Set how long an event reminder is snoozed when you tap Snooze on the notification.
Snooze and other notification actions are usually only shown automatically for the top-most notification. For others, expand the notification by tapping the header or swiping down with two fingers.
You can also snooze directly from within the event view – and see, edit or delete any active snooze. Snooze times marked with ! are set later than the event start time.
Re-notification
Set up automatic re-notification – for example to be reminded again 3 times at 15-minute intervals, until you dismiss the notification manually. Useful as a replacement for the old insistent option that was removed in Android 8.
Default reminders for new events
To set the default reminder time for new timed or all-day events, go to Event defaults and Editor settings.
Mute a single calendar
To turn off notifications for a specific calendar, go to the Calendar List (Menu → Manage Calendars) and long-press the calendar.
Adding a reminder to a single event
You can add reminders directly to each event using the reminder button in the event editor. Choose from many presets (e.g. 10 minutes before) or set a custom time.
Maximum number of reminders per event: up to 5 for Google and most local calendars; often only 1 for Exchange-based calendars.
For Google calendars you can also add email notifications in addition to standard Android notifications.
Note for all-day events: The notification time is stored as minutes before the event starts (midnight). Not all calendar types support negative values – meaning same-day notifications after midnight may not be available for every calendar.
Birthdays & Anniversaries
Notification sound, time, vibration & LED
Choose the ringtone and the time of day for birthday reminders, and configure vibration and LED. On Android 8 and above you can also go to the Android notification channel settings.
Days in advance
Set how many days before a birthday or anniversary you want to be reminded. You can configure this separately for favourite contacts and all contacts.
Pin a birthday notification
Tap the pin icon on a birthday notification to keep it visible in your notification area until you unpin it – useful as a constant reminder to call someone or buy a present.
Open contact directly
Tap the contact photo on the right side of a birthday notification to open the contact directly – available when the birthday is stored in the contact.
Tasks
Notification sound, time, vibration & LED
Choose the ringtone and the notification time for all-day task reminders, and configure vibration and LED. On Android 8 and above you can also go to the Android notification channel settings.
Sticky Date
The sticky date notification shows today’s date as an icon in your status bar. When you expand the notification area, you can see your next upcoming events and today’s all-day events.
On Android 8 and above you can use the notification channel settings to hide the icon from the status bar while still seeing the notification when the notification area is expanded.
Profile
Choose which events are shown in the sticky notification.
Tomorrow’s events & locations
You can optionally show tomorrow’s events and event locations in the sticky notification.
Other settings
Wake up screen
When this is turned on, your phone’s screen lights up when a notification arrives while the phone is sleeping – so you can see the details straight away. This uses a small amount of extra battery power.
aCalendar Alarm System
This setting (on by default) adds a safety net for calendar notifications in case Android’s own alarm system does not work correctly. If you suddenly experience issues with notifications, try turning this off and contact support with details.
Test & Debug
The Test button creates a test notification and checks for common setup issues that could interfere with notifications.
After tapping Test, you can also tap Debug to see all scheduled and dismissed events in Android’s alerts database. Support may ask you to do this when troubleshooting notification problems.
Troubleshooting
Notifications not arriving?
First, tap the Test button in notification settings – it detects the most common issues automatically. Also check whether the stock calendar app on your phone delivers notifications correctly.
In most cases, missing notifications are caused by aggressive battery saving options or third-party apps. Check whether you have a Task Killer, Anti-Virus, Battery Saver or Notification Manager app installed that might be interfering with Android’s notification system.
Unwanted default reminders being added?
If a default reminder keeps getting added to your events shortly after creation, this is caused by Google Calendar during synchronization – not by aCalendar. Turn off the default notifications in Google Calendar (in the app or via the desktop web interface).
Not receiving email notifications?
Check whether the event has been synced to the cloud. Email notifications only work for events stored in a cloud calendar (e.g. Google Calendar).
