In this post, I will show you how to collaborate with others on the same note through iCloud, directly from your iPhone.
This tip is useful if you’re using Notes to:
Create your shopping list
Plan small trips and holidays
Organise family reunions or friend parties
Collect ideas for projects like house improvement
Save / store recipes either your own or found online
… and want other people to stay in the loop and be able to edit the note by adding attachments or checking off to-do items.
