Annoying app  J. Rolland  1 star

Asks me for a review every single time I open the app...so here it is. Don’t waste your money on this app.

Wish there was a smaller marker size  a guy who reviews stuff  4 star

The 1-point size for marking up with a stylus is way too big. I like a fine pointed pen when I write, it feels like I’m taking notes with a marker instead of an Apple Pencil. Great app other than that

Some things could be better  New Hertz customer? Maybe  3 star

I like PDF Expect, but there are some things that need improving. When sending a PDF via email it slows my iPad Pro immensely. It does the same thing on my iPhone. The entire PDF is placed in the email instead of as an attachment. I can type and the letters take 5+ seconds to appear. Another thing, but minor, is the ‘edit’ selection should not be available unless you purchase it. It gets confusing when I want to add some text or marks. Again, minor. It has gotten faster, but still takes time to load the files, especially layered. If that first point is corrected I would definitely use it more often.


sync issues erode trust in the app  laylowkey  3 star

This is a review about syncing in the educational context. Trust is key in this context because so much work goes into reading and annotating, and you have to have faith that the app will keep track of that work. Unfortunately, the syncing with Google Drive is clunky, and right now is actually broken. It’s no fun reading a 40 page pdf and then finding out that PDF Expert has made several copies of the document for some reason, or worse has not uploaded the latest version to Google Drive. I’ve lost fully annotated versions of PDFs, representing hours of work. I’ve received swift replies from the developers, which is great, but I’m told a fix will come in the next update. Who knows when that will be? As far as reading and annotating is concerned, this app is amazing and would rate 5 stars.


Beware  upad3333  3 star

Purchased this app as my previous PDF editor apps have not been upgraded to iOS.11. Once you purchase the app you don’t have full access to all its features. The want another $10.99 to upgrade to be able to import photos and mark up. This is done with a secondary toolbar. These features are standard on even free PDF editing apps. Wish this was explained as an extra in the App Store.


Great tool!  Kay1cool  5 star

Love this app as it helps me to teach and mark a subject like maths in a paperless way.


need ....  dylansnah  2 star

When selecting text i always have to work my way around to find a way to select word(s) and it’s frustrating n still hasn’t been fixed after various updates. ipad pro 10.5

Best app for reading  Aung Moe Si  5 star

The best function I like is scrolling the pages. It is so convenient and quick to go from one page to another. Annotations and sync functions are also brilliant. I use pdf expert not only for ipad but also for my macbook pro. Pdf expert for macbook is also superb. Thank you so much, Readdle!!!


Superb! Best PDF Editor Ever!  bitsoldier  5 star

I have tested a number of PDF editors and none of them as natural to use as this one. Well worth the money. Easy to use, well-designed, all the tools you need to treat electronic PDFs just like you would paper. I cannot think of much to be improved. Had I known how bad the others were, I would have just waited and bought this tool. Fluid, fast, perfect for my work, research, and personal needs.


Appalling iOS 11 integration.  AmDisappinted  1 star

Expected a better job of integration with iOS 11. Manipulating files from Apple’s Files is restricted and you have to undertake most file management activities from within PDF Expert itself. The use of its Document and iCloud work areas is confusing and restricted. As a result productivity is hampered and breaks the workflow for many of the task need to perform simple operations. I think the company is designing functionality within its apps to force people to buy their app bundles and live within their eco system of apps. I for one am not willing to do this. The app should be focused on PDF functionality and manipulation and leave the file operations to the IOS operating system now available in IOS 11. Expected more from this upgrade and got self serving protectionism.


Amazing app  Dejay2001  5 star

Purchased the Edit addon with some trepidation. Result. Worth every cent! Editing PDF content (not simply annotating) is simple and actually works! Change or add text and or images, too easy. Simply amazing at this price and on iPhone and iPad.


Developer won't respond  AgEtal  1 star

Say no more... encounter a problem and the developer doesn't respond.

I’ve had a great experience using this app. It was recommended to me and it has done everything I was told it would. Very powerful!

Sapporo Brian

The center of my Paperless Universe  Sapporo Brian  5 star

I have found that PDF expert is my go to for everything having to do with meetings, meeting documents, notes, etc. everything just fits! I can even use it to open Pages and Numbers documents. This is extremely helpful when I need two spreadsheets open simultaneously... one for editing in Numbers and the other one for reading and analyzing. When I have monthly sales meetings, I can save all my spreadsheets or other documents together in one PDF and then as we have the meeting, make notes and annotations directly in the PDF. If I need an extra sheet for Note Taking anywhere in the document, I can quickly drop it in. After taking Meeting Notes in PDF Expert, I can open that PDF on the right side of the screen and then write up a report in Pages on the left side or vice versatile if I wish. It is truly amazing! Working together with the Apple Pencil and all my other “work” apps, PDF Expert is the center of my working day on my iPad Pro. With the addition of iOS11, things just really got much, much easier! No Laptop Needed!!! Thank you so much Readdle!

Best App Ever, but please add more vector shapes  jtoddowen  5 star

Please add more editing tools with vector shapes. I use this every day and it’s awesome. One of my top 5 apps.


Desktop Level Power  proftab  5 star

With Scanner Pro integration, The newest version of PDF Expert makes this software as powerful as a desktop a PDF suite. You can now scan, OCR, and annotate a PDF all in one continuous workflow. With Files integration, you can do better annotating than iOS 11 does natively. With Spark integration, you can annotate and re-send attachments with ease.


Just a Quick Ptaise  dulap2014  5 star

Love this app. Use it often and never found a glitch. Highly recommend.


Disable snapping option  frankster222  1 star

Until it is easier to access or shut off the snapping tool my one star review will stand.


Crashes after iOS 11 Update  ScottK83  2 star

It now crashes routinely after trying to open a PDF. Very frustrating. I even reset my iPad. Used to work great before updating to iOS 11. This is on a 9.7” iPad Pro. If a developer contacts me, I’d love to send the crash reports to get this sorted out.


Great App!  ShiranC  4 star

Great App


Wow!!  Thisreviewistrue  5 star

An PDF app where I can do a lot of adjustments to it and it's fillable... this app has really come in really handy in my job, it does. I use this app on a daily basis. I haven’t found issues with syncing at all. Yes I paid for the annotation ability. But worth it. Thanks
