About Casu

Casu is a premium iOS reading app for people who read closely — particularly those reading in a second language. Multi-format (EPUB, PDF, web articles, RSS, plain text), with annotation, vocabulary capture, a private journal called Sparks, and small private book clubs anchored by a Bluetooth-proximity ritual.

Read, Remember, Share.
