I take a lot of notes when I’m working that consist of random bits of information and small diagrams. A word processor doesnt work well for me, paper and pencil do. The problem with paper and pencil is that out of a whole page, I may only want to save a little bit of it and the only choice is to rewite it or cut it out. Notability on an ipad pro/mac/iphone has proven to work even better. Out of all the functionality, I mainly uise the green graph paper and black ink. It is so nice to not have to deal with a stack of paper. Plus, I can easily zoom in and out to make efficient use of the page and to keep small details neat. Talking about neat, the line quality is excellent and it really looks and feels great to write.
Apple notes could be used in a similar manner, but what I like most about notability is that it works so much like a linear roll of paper.
In addition to keeping notes, I’ve used it to make hand drawn pdf presentations.
The ipad pro version is the most useful version of this software where the pencil makes it powerful. However, having it on the desktop makes inserting clips of information easier.
