Little challenging at first but once you get the hang of it you can roll with it. So professional to be able to send or just show a document like this to a customer or a colleague. Instead of slopping with paper and pencil. Even with an app like one note having to make symbols...kinda how they should look setting aside to cut and paste. Pain. Great app.

It's super easy to use. There are plenty of options. Pricing is not clear. A $4.50 sum comes up. I'm not sure if it's per item or a certain period( month). The free version has plenty of features for a very simple SLD.
