Hey Product Hunt — Rohit here, maker of Calerto.

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?
