Meeting Alarms: Calerto
Meeting Alarms: Calerto turns events from Apple Calendar and Google Calendar into dedicated alarms with configurable preparation time. It is designed for people who need more prominent reminders for meetings, classes, and other scheduled events on iPhone, iPad, or Mac.
Overview
Meeting Alarms: Calerto is a calendar alarm app for iPhone, iPad, and Mac. It reads upcoming meetings from connected Apple Calendar and Google Calendar accounts and turns selected events into dedicated alarms with a configurable preparation buffer.
The app is intended for people who find ordinary calendar notifications too easy to miss. Alongside alarms, it provides a countdown for the next meeting, Lock Screen visibility through Live Activities, and access to meeting links from alarm rows. The listing states that calendar data stays on the device and is not modified, sold, or shared.
Features
One-tap meeting alarms
Arm an alarm for an individual calendar event with one tap or swipe, without an extra confirmation step.
Flexible preparation time
Choose a preparation buffer from common presets, or use the custom-time option described in the version history to set a more specific lead time.
Loud alerts and Lock Screen visibility
Uses iOS AlarmKit for alerts designed to sound through Do Not Disturb and silent mode. Live Activities keep the next meeting visible on the Lock Screen.
Weekly auto-alarm and pause controls
An optional auto-alarm mode arms meetings scheduled in the next seven days. Individual alarms can be paused or removed, with pause rescheduling the alarm rather than deleting the event.
In-app meeting joining
Alarm rows can surface video-conference links from calendar events, including Zoom, Google Meet, Microsoft Teams, Webex, and other supported links. Join is described as becoming available five minutes before the meeting.
Use cases
Back-to-back remote meetings
Set a buffer before each call so there is time to open the invite, review notes, and use the Join control when it becomes available.
Client-facing schedules
Connect multiple calendars, search by calendar or event title, and use color coding to distinguish client appointments from other commitments.
Classes and study groups
Arm alarms for classes, study groups, or campus events when a conventional calendar notification may not provide enough preparation time.
Busy weekly calendars
Use the seven-day auto-alarm option to prepare a week of scheduled meetings, while pausing individual alarms when plans change without deleting the underlying event.
