Can you make Wednesday game night?

The group needs 8 yes RSVPs. Tap your response — no login required.

Yes
Maybe
No

No app-store detour. No password reset. Just the RSVP your organizer needs.

No app required
Members respond through a web link. Nothing to install, nothing to update, and no app store to visit before they can answer.
No account needed
Each member gets a personal invite link. They click, choose their RSVP, and they're done — no sign-up form, no password.
Email or text invites
Send invite links by email on every plan. Plus organizers can also send by text — members respond the same way either way.
Higher response rates
Fewer steps between invite and response means more people actually RSVP — and your quorum count stays accurate.

Why friction kills group RSVPs

Every extra step between "got the invite" and "submitted RSVP" is a place someone drops off. Quarmup removes those steps.

No app to download before the first response.
No account creation blocking the RSVP flow.
No password to reset when someone hasn't used it in a month.
Works on every device — phone, tablet, desktop.
Send the link by email or text, whichever the member prefers.
Organizers sign in passwordlessly too — magic link, no password.

Lower the bar and more people show up

The easier it is to RSVP, the earlier your group can confirm the event is on. Quarmup keeps the response path as short as possible — one link, one tap, done.

No-download RSVP questions

What does no-download RSVP mean?

Members receive an invite link and tap their response directly from that link — no app store visit, no account creation, and no password. They click, choose yes/maybe/no, and they're done.

Do members need to create an account?

No. Members respond through a personal invite link with no login required. Only organizers sign in, and even that uses a passwordless magic link.

Can RSVP links be sent by email or text?

Yes. Organizers can send invite links by email on every plan. Plus organizers can also send links by text/SMS — members respond the same way regardless of how the link arrives.

Does it work on any device?

Yes. The RSVP experience is a web link that works on phones, tablets, and desktops. Members never need to visit an app store.

How do organizers sign in?

Organizers sign in with a magic link sent to their email — no password to set or remember.

Is Quarmup free?

Yes. Quarmup is free in open beta. Plus adds higher group and member limits, AI-assisted drafts, and a monthly SMS allowance for text invites and nudges.
