Over the past three years my household has used Day One as a journal. We cataloged the short time before the birth of our first daughter and ever since. With the latest release, it is possible to have multiple journals in the app — combining them is exactly what I wanted to do. Occasionally we’d catch up on those individual moments through reading of the other’s journal, but it could be improved.
An import of the classic version yields a new journal in Day One 2. Doing an import from Day One classic on both iPhones was all that was required. Enabling sync and waiting for it to finish; then doing the sync on the second phone was the last bit. Now we can see each other’s entries immediately after posting a new one and without effort.
