    Kaiten's origin

    Kaiten is based on the popular open source app K-9 Mail and was built by K-9's lead developers Jesse and Chris. By buying Kaiten you not only get an awesome email client, you also support the open source version because almost all of the new features are contributed to K-9 Mail.

    The name is a play on K-9. Kaiten is a Japanese word that means rotation and sounds a lot like K10 or K-10.
