Paper Boat lets you share a story or feeling with another Terapeas user, without your name. They can send back a kind reply. You can also catch other people's boats and reply to them.
You can also write a story and Release to Ocean. Then nobody reads it. It is a way to let a feeling go.
Go to Self Care and tap Paper Boat. The icons at the top open My Boats, Storage (replies you kept) and About Paper Boat.
