If you rely on Notes to keep track of your work and to manage your home, you'll love this new feature -- even if you mainly use it to collaborate on grocery lists.
The iOS 10 Notes app now supports sharing notes and collaborating on notes inside the app.
When you are in a note you want to share and allow other people to make changes, tap on the new person icon next to a normal share.
From here you can post to Slack, iMessage or about any other app that supports sharing. You can also copy a link to the note.
