Calerto turns your calendar into alarms you can't sleep through. Full-screen meeting alerts — not another notification you'll swipe away — with custom prep time per meeting, Apple + Google Calendar sync, a menu bar countdown to what's next, and automatic launch at login (toggle it off anytime). Pause alarms without losing them. Pro auto-alarms your whole week. Your calendar data never leaves your device. Never be late again.
I built Calerto because ordinary calendar notifications are surprisingly easy to miss when you are deep in work, in Focus mode, or moving between apps.
Calerto for Mac gives important meetings a much harder-to-miss moment:
• Connect Apple Calendar and Google Calendar
• Choose which calendars appear
• Set alerts 1, 5, 10, 15, 30, 60 minutes — or a custom time — before a meeting
• Get a full-screen alert, including during Do Not Disturb / Focus
• Join the meeting directly from the alert
• Keep your schedule on your device
The goal is intentionally simple: help you stay focused without accidentally missing the meeting that matters.
I would love feedback on two things:
1. What would make this useful enough to keep running every day?
2. What calendar or meeting workflow should we support next?
This is perfect, I always miss my importants meetings, I think this will change my life !
Does it fire while a Focus mode or a full-screen call is already running? That is the case where I lose meetings, the notification exists and I never see it.
Very helpful tool, thanks for creating it! Does it support any calendar connected to the Apple calendar or specifically iCloud ones? I've migrated to NextCloud that I connect to my Apple calendar.
@rohit_jindal3 - I like the look of this, and will be testing - I also like the lifetime option, does this also include all platforms for one payment?
