During the day, drop a line, a photo, a voice note or a mood on the cover. It takes seconds.
At night, open the book. On iPhone Duo you unfold the phone; on any other iPhone you turn it sideways. Your day is waiting on the left page, and the right page asks you one question about it.
Write a little, close the book, and the day is sealed with wax.
Everything stays on your iPhone. No account, no ads.
