IPHONE: Now you can use iAnnotate on your phone, with all of the great features you’ve come to expect on your iPad.

ANNOTATE: Choose from the pen, highlighter, typewriter, stamp, straight-line, note, underline, strikeout, photo, voice recording, arrow, rectangle, circle, and date stamp tools.

CUSTOMIZE: Drag and drop tools to your custom toolbars. Swipe between toolbars, or open the Toolbox to access all your tools.

ACCESS: Connect with Box, Dropbox, Google Drive, OneDrive (including OneDrive for Business) or open PDFs directly from email and other apps.

Overall very helpful but not exactly what I need


I am in veterinary school and I use this app to take notes daily. It is nice that you can write on the PowerPoint or other document, my main issue is that there is no way of adding a blank space next to the PowerPoint to write notes on. I am one that uses the handout 3 slides/page notes when I print because I take so many notes. Currently I have to open everything on my computer, save it as a PDF with the notes format then move it over to google drive before I can open it on the app. It is very frustrating and I have yet to find an app that will let me do this without using my computer. I hope their developers keep this in mind because I have read about students equally as frustrated with me but no solutions have come. (I would use one note because they have this feature but I only have google accounts and that requires a Microsoft account)

Sorry for the long review but this is great for those students who don't need a lot of space to write! (Except for the random times it decides to shut off but all annotations are saved)

Developer Response

Thank you for writing in to us! We have heard something similar from other students. This is something that we are potentially considering adding in the future. If you contact, you can speak with our Product Manager directly and discuss this suggestion in greater detail.

Keeps getting worse


Why does this app keep getting worse with every update? The problems with file management have been well documented. The latest change involves the navigation tool. It used to be on the left margin, and would show a list of icons representing each annotation you made, with page numbers indicated for each icon. Clicking on the icon brought you to that annotation in your document, and if you want to go to the next annotation, you simply clicked on the next icon.

Now, that panel is a pop up menu, with no page number listed. So, in a 50 page document with 25 annotations, how do you begin to decide which icon to click if you want to go to an annotation on page 30? Then, after you click on an icon, the pop-up menu disappears, so when you realize you wanted to go to a different annotation, you have to bring up the pop-up menu again. Even worse, the menu does not indicate which icon you last clicked on, so you can’t even figure out which icon is for the next annotation, let alone an annotation that might be 10 pages further in the document. I’m ready to go back to version 3, or look elsewhere.

Developer Response

We're sorry that you aren't enjoying the new update. We moved the navigation menu to the right and gave search its own section to fix the issue of the keyboard automatically popping up and having to hide it to access thumbnails, the annotations list, and the outline.

However, we have heard that users want the page numbers listed, so we are working on bringing that back in the next update. We're also planning on changing the functionality of the menu to prevent users from losing their place or having to continually click back into the menu.

Dropbox Connectivity Ruined in New Version


Using iAnnotatePDF, I had everything at my fingertips, tons of reference material for my job that I could read and annotate whether I was online or out in the field far from wifi or cellular. If I was connected, my annotations instantly zipped via Dropbox to my desktop or wherever. If I was disconnected, the changes would sync once I got within range again. It worked PERFECTLY for me. Then came along the FANTABULOUS, EXCITING and INSANELY GREAT iAnnotate4, and now the thing seems to be designed solely for those who are ALWAYS CONNECTED to the cloud, or those who are willing (and able) to constantly move their documents back and forth via iTunes or something.

I may be wrong (I often am) and there might be a way to make it work like before, but like most developers these days, you cannot find help.

It WAS a good app back before the “improvement”, now I’m looking for some other way to do things the way I want to do them, not the way some dude in tight-jeans and green hair thinks is spiffy. Ruined my experience and opinion of this company! IF YOU HAVE A WAY I CAN SYNC TO DROPBOX WITHOUT CONSTANT CONNECTIVITY TO THE CLOUD PLEASE LET ME KNOW.

Developer Response

We are very sorry that you are do dissatisfied with the new update. Other users have expressed the same issues and concerns to us and we will be bringing that feature back (automatically saving to the app) in our next update. Once again, we are very sorry you are experiencing these problems, but we hope the next update will make your experience perfect again!
