I’ve used a bunch of free note-taking apps since I was a college student in the mid-2000s. Google Keep doesn’t have the most features, nor is it the flashiest or simplest of the apps I’ve tried -- and yet I absolutely love using it. I have a Keep notebook for each of the Google accounts I maintain (one for my motor sports endeavors, one for my side hustle and one for the rest of my life) and they have all helped me easily record, organize and utilize my thoughts on just about anything.
