The app has a ton of useful features such as highlighting, writing, bookmaking, etc within the document. What renders the app borderline unusable at times is that sometimes it will lose your edits for no reason (even if you're saving religiously), and you never really know whether it'll just lose the edits since the last save or all the data saved or not for the past couple weeks. I've switched from the app to my desktop briefly and come back to the app to find that all my recent annotations and bookmarks have been lost. Auto-save hasn't helped me at all because of this issue.

By far this is the strongest PDF stylus annotation app available (the only true competitors are MS Reader & to a lesser extent Foxit Mobile). I liked the old version of Drawboard, but it had a lot of issues. These latest updates have pretty much addressed all of my issues with both this app, and pretty handedly surpasses the other Win8 PDF inking apps. I emailed the developers a lot, and it seems they were really listening. The latest updates have fixed the prior corruption issues. Inking remains very smooth, and the interface looks great.

This app is well designed and has useful features, especially using a surface. Drawboard seems to have improved substantially in terms of stability! Keep it up!

I was struggling trying to find an app would allow me to highlight and make notes on PDFs. OneNote failed and others were not exactly user friendly. Drawboard PDF was a perfect fit. Once I made my favorites on the side, annotating PDFs became very simple and a pleasure to do in Drawboard PDF. The tools they had were exactly what is need to markup a PDF. I am currently using Drawboard PDF for my Cisco Certifications study, and Drawboard has not failed me yet. I like it because: * The tools are easy to setup * The pens have many customizations such as width and color levels * Navigation is a breeze with Drawboard * Saving the PDF in its native format with the markups is invaluable * Easily uses Cloud storage * Favorites menu bar is extremely handy and makes it easy to use To sum it up Drawboard is fast, effective, and easy to use.

After trying other PDF programs I've found that this one is the most useful, easy to set up and write annotations. I would like to see more features included, and a bit more stability (like any Windows app) and this will be the best Windows app that I have ever used. It is the closest I have found to Good reader on the iPad. lease keep improving this app, as it is clearly on the path of greatness. Great updates!

I needed to annotate my PDFs and this is the best app in the Store to do this. Feature request: Make pen settings 'sticky'

open up a technical PDF and notice the differences in font quality between drawboard and ma reader or adobe reader, its huge. so much clearer and sharper

Returning to grad school I was looking for something to be able to annotate pdfs and this tool is amazing. While other apps may allow you to markup a pdf, not many will save those markups to the file in a format that is consistent with the native Acrobat markup formats. I hardly ever buy apps, but this one is surely worth it! Store your files in a cloud based location and use this app for reading and annotating and you're all set!

Fantastic application for studying PDFs on my Surface Pro 3. I giving it 4 stars instead of 5 because the thinnest pen setting is not thin enough. This makes it so that I have to write/draw some things larger than I'd like. Other than that, it's exactly what I hoped it would be -- very fluid and quick with all of the important editing options. EDIT: With continued use I've noticed a few larger problems: 1) the erase function using the pen on my Surface Pro 3 is buggy. Sometimes it doesn't do anything, and other times it just warps my writing. 2) I've been using a 400+ pg document with lots of photos, and there are times that the screen will go entirely white until I zoom out and then back in.

Latest version is very good. The app keeps improving. Amazingly easy to use, great annotation features. 100% worth the money

I was a huge fan of using OneNote 2013/OneNote for classes, but became very disappointed that they would probably never solve the blurry rendering of my PDFs that I would transfer. They still didn't address the issue and probably will never until a whole new release of Office. That is why I moved all my note taking to Drawboard PDF. It uses the actual PDF works flawlessly (if you have a surface pro model) working perfectly with pen and touch. What I miss the most is all the special organizational features that OneNote has! So in spite of everything else I will still "print to" OneNote because I can still have it all in one place and add what ever I was to it later. That isn't the applications fault. It is just how the company intended for it to be and they obviously focused on annotations and features than organizational quirks. Nothing wrong with that. If you are a student or an annotation master this is a MUST BUY (or find it on sale at some point like I did).

Good app. Good concept and feature set. I have been experiencing frequent crashing when selecting certain bookmarks in certain documents. Support has been very responsive and I'm told the problem has been identified and should be fixed in a few days. Meanwhile they have pointed out a temporary work-around to avoid the crashes. Without the frequent crashing, this app should be my go-to tablet mode PDF reader. I like it. I expect to update my review to 5 stars once it's actually fixed. Kudos to Drawboard support. Edit 2/14: New update had made the app unusable again. Every time I try to close a document, the app crashes to the background. On a hunch I uninstalled, restarted, and re-installed Drawboard, and the problem has disappeared. The other problem I was having with bookmarks seems to have gone away as well. The only problem remaining is that text selection is still erratic and difficult in some documents (that Reader has no trouble with). Otherwise excellent app.

If you're a student or academic needing to mark up pdf articles and books, this is by far the best app. Very intuitive interface and all the features you need. The development staff is very responsive and they're constantly bringing new features on board.

Wonderful app! Runs fast, has all of the basic features, and is intuitive and easy to use. Would like to see larger native drawing sizes, but that's more of a suggestion than a complaint. A smaller pen tip would be nice also.

I was looking for a PDF reader that would let you draw on it so that I could write on PDF's of scanned music. This is already well worth the $5 and I plan on using it a ton. The pen feature lets you mark up sheet music, and the bookmarks tab is great for navigating long document such as set lists and method books. It even lets you erase/undo changes you made and saved previously so you can go back in and edit tempos, cuts, etc. Overall just plain awesome!

Overall it's very good, and the new version takes many steps forward in a good direction, but it still has some limitations. 1st, drawing has lag, so it's difficult to see if you're drawing correctly, and the sampling time seems too low, because if you draw too fast it becomes some weird straight lines, different than the native PDF app that even interpolates the lines to become smooth. In the new version, it also takes a while to show the final line if you're drawing on top of big PDFs, like ones with image backgrounds. 2nd, there is no partial erase, it works more like a selective undo (which isn't bad, but sometimes you need to erase a part of the line). 3rd, when you save your notes it gets rasterized to inferior quality, making some hand-writing difficult to read. Fifth, you can't erase notes after the file is saved. (I would suggest the developers to create a custom file type to store Drawboard files, and keep the ability to export it to PDF)

I've finally found the PDF note taker I needed! Does everything you need to take notes in like a lecture or meeting. Highly recommend this app, saves great too. They keep updating with even more user friendly, intuitive and customizable features. If you need a program to annotate and take notes, particularly for presentations, lectures or meetings, there is no other app that I have found that compares.

I like this app. I use it for studying PDF books, and my kids like it for coloring. Questions: Is there a way to get even more color options for the highlighter and pens? also, is there a way to get finer point for the pens than 1? *March 5 addendum: now I can only use 1 pen at a time, what happened to the other one?? I loved having two pens set so I could alternate colors. *March 23 addendum: WHOA! I just discovered the favorites bar. It stores your favorite tools, and you can add or remove tools at your leisure. THIS IS AWESOME. Now I have my most commonly used pens and highlighter a my finger tips with out having to change the pen all the time. What a great update, I love you drawboard PDF. All my iPad-toting friends can't believe that I can take notes right in the margins of my study material in my own handwriting :)

I am currently a medical student w/ course notes and text books in PDF format. Have been using Notability on the iPad for the past year and now found this after purchasing a surface pro 3. The scrolling is very smooth and allows me to scroll using my fingers and annotate w the pen without any problems. This app justifies me using a Windows tablet to take notes over an iPad. Much better than Adobe or Microsoft's PDF options. Was definitely worth the $10.

UPDATE: This application is under active development and gets regular, meaningful updates those with a pen will get more value, this app makes wish the pen on my Dell Venue Pro worked Better. it provides a great inter face for creating and annotating PDF files, Well thought out and executed. I thouvht One Note would be my go to app but so far it has had to share equal time with Drawboard

Would highly recommend in terms of functionality. I use this as a music student for composition work and have found that the app can handle the rendering, but also saves directly to the PDF itself without converting it to another file type. Works smoothly and effectively for those who like to highlight by hand rather than by mouse. Well done. 8.1 half-way window split support would be appreciated!

I work with PDF files constantly. I had been using Acrobat's pen tool, but the results were less than satisfactory. Drawboard is light years ahead of Acrobat. Plus, it's a metro app so that I can easily use it in split screen mode. Highly recommended

One of the best aspects about Drawboard PDF, which is unfortunately lacking with most other Windows apps, is the company's commitment to continue improving Drawboard PDF. New improvements are constantly added with each update, and their attention to detail in striving to develop the most capable and intuitive PDF app on Windows makes this Drawboard vastly superior than any other pdf program in Windows 8/8.1. With that said, the program is very buggy (i.e., inexplicably crashes, doesn't save annotations, doesn't allow me to sign into premium account, etc.). Once the bugs are addressed, the app will be the best.

It is refreshing to find an app that hits all the marks like Drawboard PDF does. The end

Was maybe 4 stars before the 9/2 update. 2 stars the update before that (had problems losing annotations). Now it's a 5. This app keeps improving. Worth every penny. I no longer have crashing issues. Pressure sensitivity is supported now. And the window resizes properly when moving between my Surface Pro 2 and external monitors. I have no complaints left. Good job guys.

As one of Jehovah's Witnesses, I was looking for the most versatile and easy way to highlight, underline, and make notes in my study material for the meetings. After trying literally two dozen apps for both the Ipad and the Surface Pro, I have found it. The surface Pro 3 with this drawboard app is what I've been trying to find for years. It is perfect. The tool selection wheel is very thoughtfully designed and easy to use. But then we can choose our favorite pen, pen strokes, colors, highlighters, etc. and add it them to a quick pick list of our favorite tools. This allows me to quickly and easily write notes on my Watchtower article, insert notes with additional research, switch between different colored highlighters, erase, undo, move text boxes, etc. Then I can also zoom in and out without disrupting all the mark ups I made. I can save the entire PDF to any PC, and then open it again on another device. I could not be any happier with this PDF annotator.

As a Ph.D. student, I have tons of PDF's provided by my professors and colleagues that I want to read. This is the first app I've used that allows me to effectively mark these up on a touchscreen environment. The support for the Surface Pro 2 is fantastic, and could only be better by including pressure sensitivity (not a huge issue for me, since I pretty much write all my handwriting with A BOLD STROKE, but might be important for some). Overall, a great app, and I'd love to see future updates that include better Bookmark support, etc. Still, an AMAZING app for PDF markup, and with auto-save, I don't need to worry about crashes killing my work. Props to the developers, and hopefully future updates will make it better. A couple suggestions: maybe add support for the button on the SP2 pen to switch between two different inking modes? (I don't know if this is possible). Pressure sensitivity. That's it, but still, a great app that you should support!

I previously gave a bad review for this app. They listened n fixed everything. This is by FAR now the best app on metro to take notes on PDF. Def worth it. Good job guys!

Microsoft store was not helpful in getting this program activated. Dealing with this on a Sunday day was frustrating but late in the day I got an email from the company who are located in AUSTRALIA!!! No wonder they didn't answer immediately... It was the middle of the night there. Their technical support was very helpful, telling me to just restart the computer and the license would work! And it did! Now that I have used it for a day, I don't think I could function effectively in business without it!

This is really a great PDF reader. + Digital Ink support modeled after MS. I mean the pen and touch do different things, like they should! Pen right, touch pan. + Great font rendering. I really like the font rendering over the MS Reader. On my Surface Pro 2 with a 200+ DPI screen it is quite noticeable with two pages open. + Content creation. Create, merge edit PDFs. + ABSOLUTLY the best pen annotation experience of any PDF viewer. On par with the OneNote App. - Costly. It didn't cost $9.99 when I started using it, but if you compare it to what people are offering for free, you ARE getting your money's worth. The developers really stepped up and made this a great program. I have made it my default PDF viewer, earning a 5 star rating.
