What is OnThree?

OnThree is the simplest way to publish a recurring schedule and share it with everyone who needs it. You create the schedule, share one link, and your subscribers' calendars stay up to date automatically. No group chats, no spreadsheets, no "did you see my message?"

How it works

1. You make the schedule. Type your events, speak them, snap a photo of a flyer, or import from a file. The AI handles the rest.
2. You share one link. Anyone can open it. No app required. They see the full schedule in their browser.
3. They add it to their calendar. One tap subscribes them. Apple Calendar, Google Calendar, Outlook: whichever they already use.
4. Updates happen automatically. Every change you make flows into every subscriber's calendar. You never have to remind anyone again.

Who uses OnThree

OnThree is built for anyone who runs a recurring schedule and needs to keep a group of people informed. Coaches, teachers, rec league organizers, club leads, event coordinators: if you've ever had to send "the schedule changed" messages to a group, OnThree is for you.
