Buggy and hard to use
I purchased this app because it says you can start with a PDF. I wanted to mark up a floor plan in PDF. The import worked but it only imported a small section of the single page PDF document. I took a screen shot and used that instead. Even those the application is hard to use (you have to confirm every action you make in the mark up mode.) and the tools were really hard to find. Not intuitive at all and the guide at the beginning only points out the obvious controls that have text labels. Ugh. lastly, after I spent about 30 minutes marking up my plan, the app crashed and I lost all of my work. Please address these issues! It is experiences like these that I wish Apple were even more selective for their App Store OR allowed us to try before we buy. Guess I'll keep spending money trying to find a tool that will work for me. This Apple Pencil is starting to feel like a waste of a purchase.
