I use drawboard pdf on a near daily basis to markup documents, and for notetaking. I have been using it since it first was introduced and have been extremely happy with it. I recently had a problem with drawboard freezing intermittently after an operating system update. I contacted drawboard support. They were courteous and quick. They had the problem resolved within a couple of days. I am a very happy customer.

I rarely recommend products, but I've found Drawboard PDF to be an incredibly useful app. So much so, that within a few days of using it, I ended the trial early and signed up for the full paid product. Quick context. I'm in the middle of building a house, and the architect & other consultants routinely send me PDFs and ask for detailed markup. I'd been struggling through Kami, Adobe (both paid licenses) and looking for a better option. I tried Canva. All were limited. What I wanted was something that had the power of a vector drawing program, with layers, snap to, reusable object libraries, shapes, different fill types, etc. and -- amazing, hard to find - actual copy/paste. Trying to edit on top of a PDF much like I would in PowerPoint or Google Presentations. I also used Kami a lot for adding signatures / other basic editing, as well as merging / cutting up PDF files. Drawboard PDF does *all* of this. It is by far the most full-featured program I've found (and I've tried dozens). So much better than Adobe's own product in the space that I'm scratching my head why. Using it is very easy. Features make sense, and when you try something it generally works like you'd expect. This product has vastly improved my workflow with my design and build team.

Drawboard PDF offers a smooth and professional experience in annotating and editing PDF documents; it's very versatile and easy to take notes, draw free-form shapes, underline and even write directly and accurately on my PDFs with the stylus on my tablet's touch screen. By having a neat interface it's possible to access any of its tools or move my annotations around with ease without overwhelming me or affecting the flow of my activities.
