Glance Back offers a unique take "journaling":
With this Chrome extension, once a day at random when you open a new tab, Glance Back will quickly snap a photo of you and inquire: “What are you thinking about?”. Once you type your answer and press enter, the photo and thought will be collectively saved to your history of glances, cumulatively creating an archive of moments you share with your screen.
In My Machine and Me, Greta Rainbow chronicles a year of using Glance Back for the Los Angeles Review of Books:
My time-lapse is documentation of a working woman slowly aging. An accumulation in lockstep with decay, and my screen is a grave marker. I’m getting better at writing, here. I’m deepening my frown lines, here.
