I have been using Day One, a journaling app, for years. I’m not an avid user. I’m lucky to average two entries a week. However, I do try to capture places we go and family events that are out of the ordinary. The biggest motivator to do this is the printed book I buy at the end of the year. It is well-made and a pleasure to thumb through from time to time. If you use tags right, you can even make a “public” book easily if you wish to give them as gifts to family members.
