A quiet space to write, and to share.
kaku is a journal used by runners, cyclists, creators, and nature lovers. People who think while they move and want a calm place to put it down.

Most apps track your pace and your followers. kaku tracks your presence.
kaku is a personal project, designed and built by me, John Wiseman. I'm a runner with two decades of web development experience. I wanted a new relationship with online journaling and couldn't find a quiet place to write, so I made one. Simplicity shapes every part of kaku, from the typography to the feature set, so the writing can breathe.
If you'd like to be part of the early trail team, let me know.
