Signup sheets without the ads

The modern signup sheet for potlucks, conferences, and volunteer shifts. Participants tap a link, pick a slot, done — no accounts, no ads, ever.

Free includes reminders, calendar invites, QR codes, printing, and CSV export.

No ads, ever

Your participants are parents and volunteers, not ad inventory. Every tier is ad-free — that's the whole point.

No participant accounts

Link → slot → name and email → done. Everyone gets a magic manage link to edit or cancel on their own.

Built for phones

Most signups happen in a group chat. Every screen works one-handed on a phone — and every sheet prints cleanly too.
