I too rely on DayOne for my daily journaling, which for me is more of a writing practice. I try to write 500 words each day, covering what's happening as well as stray thoughts, whatever they may be. I have long admired DayOne, but it wasn't until they added the web version that I could start using it in earnest, because I spend my work days on a Windows PC. The web version has a ways to go before it matches the Mac version, but it works well enough for my needs.

One question for you: Do you make use of multiple notebooks in DayOne, or keep all your entries in one notebook?
