One-off lists you finish and file away. Recurring lists that come back daily, weekly or monthly, and quietly keep a record of what got done.
A shopping trip is a one-off — you tick it off and it's done. Chores, bills and routines recur, so Listy resets them on their own schedule instead of making you do it.
Send a link and a shopping list is on both phones. You'll see who ticked what, as it happens.
No streaks, no badges, no nagging. Not finishing everything is normal, and Listy doesn't make a thing of it.
