What you can do today

Reply without an app: The host shares a link. You reply in under a minute — no login, nothing to install.
One profile per person: Save the reply as a profile for you or your children — and reuse it for the next invitation.
Share on your terms: You decide what a link shows, see how many times it has been opened, and can revoke it at any time.
For hosts: every reply in one place: Create an event and share the link in the group chat. Replies come to you in Omhu — not scattered through the chat thread.

Household and groups: Several adults caring for the same profiles, and groups that reuse answers already given.
