## What is Swap!?

Swap! is a shared diary app for you and the people closest to you.

Write alone, read together.
Create a private diary book, invite your friends or family, and share the little moments of everyday life.

■ Jot down moments during the day
Capture what's happening right now with a quick note from the home screen.
You can share one note to several diary books at once.

■ Write your diary at night
At the end of the day, write a diary entry with a title and body.
Forgot to write? You can still write yesterday's diary the next day.

■ Private diary books, invite only
Create a diary book and send an invite code. Only people who enter the code can join.
No strangers, no public feed.
You can set a member limit and reset the invite code at any time.

■ As many diary books as you like
One for family, one for your best friend, one for your club.
Pick a cover color for each and build your own bookshelf.

■ Get notified when members write
You'll get a notification when someone in your diary book posts.

■ Friendly for night owls
Choose when your day starts, so entries written after midnight still count for the day you're wrapping up.
