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.

I am 70+ years old and have been looking for this app for many years, as I have very bad tremors and can no longer sign my name much less draw a schematic. I have tried many other apps that looked good out of the gate, but failed miserably in the long run. This app isn't perfect, but it is as close as I have been able to find to suit my needs without spending thousands of dollars. Thanks for allowing this old man to get back in the game. Regards

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.
