I use apps as well. But I also like to go “old school”. I have a paper file on all of my clients and I find that taking it out of the cabinet and looking over my notes, their feedback and goals with the file folder in my hand makes it real for me. Sometimes I like to bring it out and look it over with the client when they are working through a set back or rough patch. I think the concrete quality of what used to be referred to as a “hard copy” is motivating. And there is research to support that retention of information is better when you actually write it out by hand and read your own handwriting over in review.
