Lists is for checklists, groceries and packing that more than one device needs to see at once.
Three styles
- Checklist / tasks: rows with a due date, an optional repeat, and an assignee on shared lists.
- Grocery: items are sorted into aisle sections (Produce, Dairy, Bakery and so on) as you type, so a list reads the way a store is laid out.
- Packing / template: build a list once (Weekend trip, Camping, Moving day) and reuse it with "Use template" whenever you need it again.
Adding items quickly
Type naturally and Atrium figures out the details — "call plumber tomorrow 9am" becomes a task due tomorrow morning. Reordering is drag and drop.
Sharing
Any list can be shared. On Family and Business, shared lists support assignees, so everyone can see who has which item. A change on one device reaches the others in about a second.
Where it shows up
A list item with a due date also appears on your Calendar alongside your other tasks, so you only have to check one place.
Encryption
Lists, items and list names are end-to-end encrypted, the same as the vault: they are encrypted on your device before upload, and our servers store and sync ciphertext they cannot read.
