OpenHour V2OpenHour guide
A social layer for the calendar you already have
OpenHour is not another calendar you have to maintain. It connects the schedule you already use, translates it into shareable availability, and helps friends turn the best overlap into a plan with its own guests, chat, and photos.

How it works
Keep your current calendar
Connect supported sources and decide which calendars count as busy.
Share only the useful signal
Friends can see availability instead of a copy of every private event.
Make the social plan
Create the plan from a shared opening and keep the conversation attached.
Why not create another calendar?
A second calendar creates duplicate work and becomes inaccurate as soon as somebody forgets to update it. OpenHour uses connected calendars as the source of truth and adds the social coordination that general calendar apps do not provide.
What happens after the event
Past plans remain useful. Friends can reopen the conversation and the photos associated with that specific plan instead of searching across a camera roll and several message threads.
Common questions
Does OpenHour replace Google, Outlook, or Apple Calendar?
No. It is designed to work with existing calendars and add friend availability and plan coordination.
Can I add something that is missing?
Yes. You can add availability blocks manually or import a class schedule from multiple photos.
