Looking for an iPhone app where users can collaborate on a shared list of text. They can add or remove items. The app icon or widget should show the number of items on the list (e.g. notification/unread count).
Similar to a to-do app but a lot less functionality needed (no due dates, only text, etc). Perhaps a to-do app is the best way to do this, but perhaps there's something simpler. Was thinking about Airtable for the list but couldn't figure out the display count part.
