Calerto: Meeting Alarms

Turn calendar invites into loud meeting alarms. Never miss a standup, client call, or deadline again.

Calerto is the meeting alarm app that turns your calendar invites into loud, impossible-to-miss alarms — so you're always on time.

MEETING ALARMS THAT ACTUALLY WORK Silent calendar notifications are easy to miss. Calerto reads your upcoming meetings and sets a dedicated meeting alarm with customizable prep time, so you get a real alert before every important event.

SYNC YOUR CALENDARS Connect Apple Calendar and Google Calendar in one place. Every meeting invite becomes a meeting alarm you can enable with a single tap.

CUSTOMIZABLE PREP TIME Set a buffer before each meeting — 5, 10, 15, or 30 minutes — so you have time to join the call, review notes, or grab coffee.

LOUD, RELIABLE ALERTS Built on iOS AlarmKit for alarms that break through Do Not Disturb and silent mode. Live Activities keep your next meeting visible on the Lock Screen.

PRIVACY FIRST Your calendar data stays on your device. We read events to set meeting alarms — we never modify, sell, or share your schedule.

PERFECT FOR • Remote workers juggling back-to-back video calls • Sales teams with client meetings across time zones • Students with class schedules and study groups • Anyone who's ever been late because a calendar ping got buried
