Join a list in one tap. No account, no setup.
Invite someone to a shared shopping list and they're adding items in seconds — no account to create. Add "milk" twice and it bumps the quantity, not the row count.
Sundry is a shared shopping list built around the moments that usually cause friction. Send someone an invite link and they're in the list immediately — no account, no app-store detour required first. Add something that's already on the list and it merges into one line with the quantity updated, instead of piling up duplicate rows. And the things your household buys often are one tap away, instead of retyped every week.
Tap an invite link and you're adding items to the list right away. No account to create, no password to set — the person who invited you did the setup.
Add "milk" when it's already on the list and Sundry bumps the quantity instead of adding a second "milk" row. The list stays a list, not a scroll of duplicates.
The things your household buys most land in a quick-add shelf, so putting them back on the list doesn't mean retyping them.
