A clearer reminder

Main features

Make room for the way you plan

Choose timing and controls that fit your day. Alarm behavior differs between iPhone and Android.

iPhone & Android

Give your next meeting an alarm

See what is scheduled before meetings begin. On Android, choose Full alarm or Normal notification. On iPhone, choose Always Sound or Respect Silent Mode. Normal notification and Respect Silent Mode follow system notification settings.

  • ✓ AlarmKit or standard notifications on iPhone; full-screen alarms or normal notifications on Android
  • ✓ Respect Silent Mode needs notification Alerts and Sounds, supports up to 48 pending app notifications, and may return to Always Sound if a later schedule exceeds that budget
  • ✓ On Android, alarms and widgets are restored after reboot and rechecked in the background
iPhone & Android

Set the time you need

Add or remove reminder offsets per event, set a custom minutes-before value, or apply global defaults. Choose which calendars can trigger alarms and filter out the noise.

  • ✓ Per-event reminder overrides and global reminder offset controls
  • ✓ Calendar selection — pick which calendars can trigger alarms
  • ✓ Optional filtering to ignore all-day or unconfirmed events
  • ✓ On iPhone, App Reminder Only changes app alarm timing without editing Calendar alerts. Fresh installs start with a two-minute offset; saved choices are preserved.
  • ✓ For eligible writable Calendar events, separately preview and confirm Calendar-alert replacement. Restore it later when the source still matches the saved state.

Alarm behavior on your terms

Use Silence all for an event and its pending snooze, then Restore eligible future alarms. Open a supported meeting link with Join, open the source calendar, or confirm deletion of an eligible event or occurrence. A deletion may sync through your calendar account.

Choose Full alarm for a custom alarm screen, sound, vibration, voice, and snooze controls. Normal notification uses your phone’s notification channel and Do Not Disturb settings without opening the full alarm screen.

  • ✓ Full alarm: device alarm sound, repeat-until-dismissed, vibration, and spoken announcements
  • ✓ Full alarm: configurable, reorderable alarm-screen buttons
  • ✓ Full alarm: snooze, snooze-before-event, dismiss, and dismiss-all-future actions

On iPhone, Always Sound uses the AlarmKit screen with system Stop and a Snooze or Join action. Respect Silent Mode uses standard notifications; tap one to open Stop, Snooze, or Join in the app. Silent Mode, Focus, and notification settings can mute or delay it.

Widgets on both platforms

Check upcoming alarms on your Home Screen

See the next alarm and what is ahead without opening the app. iPhone offers Small, Medium, and Large Home Screen widgets, plus a navigation-only Lock Screen widget. Android widgets adapt to your launcher grid.

The iPhone Event Alarms master control supports both delivery modes. Individual alarm controls in Respect Silent Mode open the app; Always Sound and Android support direct widget alarm controls. If saved state needs recovery, open the app.

How it works

From calendar to alarm, automatically

The same shape on both platforms, using each one’s alarm system.

01

Reads your calendar events — plus incomplete Reminders with due dates on iPhone.

02

Finds upcoming reminder times and schedules an alarm for each one.

03

Delivers the scheduled alert: AlarmKit or standard notifications on iPhone; Full alarm or Normal notification on Android.

04

Lets you snooze, dismiss, or silence reminders — preferences stored locally.

05

Shows what is next in interactive Home Screen widgets.

06

Keeps alarms current: reboot recovery and repeated verification on Android, best-effort background audits on iPhone.

Permissions

What each permission is for

Permissions support reminder delivery and the calendar actions you choose. None is used for advertising or tracking. The two platforms ask for different things.

iPhone
AlarmKit
Schedule and present Always Sound alarms through Apple’s system alarm surface.
Notifications
Show standard alerts and play sounds when you choose Respect Silent Mode; Alerts and Sounds must be enabled.
Calendar
Read events for alarm times; optional source edits require separate confirmation.
Reminders
Include dated incomplete Reminders; optional source deletion requires confirmation.
Android
READ_CALENDAR
Read calendar events and reminders to determine alarm times.
WRITE_CALENDAR (optional)
Requested when you choose Allow & delete for a supported calendar event or occurrence. The change may sync through your calendar account.
POST_NOTIFICATIONS
Display alarm notifications.
SCHEDULE_EXACT_ALARM, USE_EXACT_ALARM
Improve timing accuracy for alarms.
RECEIVE_BOOT_COMPLETED
Restore and re-verify alarms after reboot.
WAKE_LOCK, FOREGROUND_SERVICE, VIBRATE
Deliver active audible and vibration alarm behavior while in service mode.
USE_FULL_SCREEN_INTENT, SYSTEM_ALERT_WINDOW
Support full-screen presentation in Full alarm mode; not needed for Normal notification.

Note: on Android, alarm reliability can vary by device vendor settings — excluding the app from battery optimization can improve consistency. On iPhone, Always Sound uses AlarmKit; Respect Silent Mode uses standard notifications that can be muted or delayed. iOS decides whether and when background refresh runs.

Privacy & data handling

Local-first by design

  • ✓ Calendar, alarm, settings, widget, and diagnostic data are processed on the device.
  • ✓ No account or ads. Calendar and Reminder content is processed on your device.
  • ✓ Anonymous usage analytics and sanitized reliability reporting can be turned off at any time in Settings.
  • ✓ No advertising or cross-app tracking; calendar and reminder content and local diagnostic logs are never sent to analytics.

Requirements & limitations

Good to know

  • ! iPhone requires iOS 26 or later and is not available for iPad. Android requires 11 (API 30) or later.
  • ! Reminders may be delayed if external calendar sync is delayed on the device.
  • ! Choose Full alarm or Normal notification on Android. Normal notifications follow phone, channel, and Do Not Disturb settings. iPhone Always Sound uses AlarmKit; Respect Silent Mode uses standard notifications that iOS may mute or delay.
  • ! Timing depends on the operating system: Android exact alarms are affected by permissions and manufacturer settings, and iOS background refresh is best effort.
