Calerto for Mac - Full-screen meeting alerts for your Mac

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.

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?

 The full-screen alerts during Focus mode are really useful. I always end up missing meetings when I’m focused on work

 yeah i was also missing meetings. I use this app and pair with calerto ios app. I never miss any meeting now.

 Yeah, that makes sense! Having it on both Mac and iPhone sounds like a good way to avoid missing meetings. I’ll give it a try.

- 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?

 Thanks i put lot of effort on UI. Of course claude build. yes this for all the platforms. You can use app on iOS and Mac with same subscription.

Damn! I really like this!!!

 thanks let me know if you have any feedback. Also check our ios app

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.

 yes any calendar connected to apple calendar shows there. You can enable and disable the calendar’s in app.

The full screen alert is the part I would worry about while screen sharing, since it takes over the display in front of whoever is watching. Does it hold back when a share is running?

 Thanks for the feedback. It doesn't take care of that situation right now. we will add that in future release. This is really good feedback. We would like to share 1 year free subscription for the feedback. Please email us on

i do a lot of screen recording is there any feature to change the style of popup i mean a more discret one when i do screen recording ?
