The Fastest PDF Reader App Reviews

I always keep some of my favorite e-books and game manuals with me in PDF format so that I dont need to lug them around, but some of the more image intensive stuff has a tendency to load at a page a minute and crash every time I try to load it in my old PDF viewers. Im a fan of speed reading, and this app makes it all possible. 5 stars for helping scratch an itch, and an excellent update schedule. Looking forward to more.

Since the launch of the iPhone, I have been waiting to be able to view large blueprints on all of my iDevices, and while there are many great pdf solutions out there, this is the ONLY one that is able to effectively allow me to do this. As a Project Manager with a number of ongoing projects, not having to carry paper blueprints with me anymore is just a huge boon for me. I have spent over $100 on all kinds of different Apps that would potentially allow me to what this App does for $4. The pre-rendering process finally makes it effortless for me to glide, and I mean glide through huge blueprints. It blows me away. The App is not without issues, you will often get a prompt that says pre-rendering will allow you to view the document easier, but the only option it gives you is to ignore the prompt not initiate the pre-render process. They are updating it on a regular basis, so Im sure these little issues will get resolved. However, this is simply an amazing solution on the iPhone, and even more so on the iPad. Bravo!

I needed a PDF app to open large land location maps in a small amount of time, and this delivers! My only suggestion is having a search ability for written documents to search for words and phrases.

Works extremely well And for big files with large formats I use large viewer from the same vendor

Been using this App since iPad1 came out. Superb! Recently added annotations/markups. Excellent. Customer service is perfect! They care. Upgraded the app when I emailed - and the issue wasnt even a bug. Brilliant.

The description lead me to believe i could add my signature to PDFs within this app... for the price i paid. The truth is, it will cost you 4 bucks. I already have an app to view PDFs. How misleading! Deleted app.

The sponsored function to write on PDF files is an additional in-app purchase. As you get it, you realize its just useless.

Love the speed of rendering and the accuracy of the content. Support was phenomenal. John and the team put more time and personal touch into solving my problem than I have ever experienced.

Nice application to link drop box account.

As an engineer Ive always found there is dismal support for large complex drawing say the standard 36 by 24 inches page size on the iPad. Heck a large project might have 100+ sheets. Those are impossible to view before I found this product. Now they open in this product in a few seconds, paging is great, swipe and there is the next page. Talked to the support staff, great support they really care about eking the last dregs of performance out of my iPad. Also fed it a 927 page PDF I had on the principles of the mechanics of brittle fracture of materials, ya ya who else but an engineer needs something like that on his iPad, but would I rather carry the book around? I think not. As a bonus I discovered they also make a Fax Reader, thats the only product Ive seen in the store that will let me read faxes and not be tied to some pricey web service that is selling fax pages at a buck a shot, dont need to send faxes, just need to see them. Silly that Mail wont show more than the first page and I have to buy another product to see page two. After upgrading I found they didnt miss a beat, they tell me they moved stuff from their Map app into this app to improve overall performance and to ensure page to page movement was even faster.

Does what it says it will do. Made the paging thru my math text book really fast, other stupid readers just take forever for the diagrams to draw. But after doing the pre renderings button, I can flip between pages just as fast as I can flick my finger. Other apps might have more features at the moment but for me its all about the drawing speed. A month later Ive loaded all my PDF text books into the app, actually Ive stored them in the Dropbox area, but since its cached I have access even if Im not on the internet. Even handled the few password protected ones I got from my professor. I thought my math textbook paged fast, but when I got to load my differential equations one the line charts just draw so fast I couldnt believe it.

Used the pre-render function, then it just made viewing large PDF documents so much faster. Who has time to wait for some app to show the page, I noticed it cleared all the lag time up in viewing my automobile user manual since that seem to take 10 seconds to draw the shaded dashboard in that other PDF Reader app I was using. For sure these guys think different and have a better way to show PDF pages.

This reader is superb. I dont use the Drop Box, but purchased the full version anyway......I was testing pdf readers for my daughter who has 100+ page documents to read for college. I was impressed and purchased the "reader" version for her. After an approx. 3 minute rendering, her files were easy to read page after page with no screen recalculating. I use this app myself, recently viewing multiple page home insurance quotes. Zooming and scrolling the documents are instantaneous. Ive used this app to view 11x17 spreadsheets, again with instantaneous views as I zoom and scroll through parts of the documents. Tech support is superb. I received an email reply within an hour. This was a Sunday evening. My query had revealed a slight bug in the program, it was promptly addressed, added to the recent update, and followup emails kept me informed.

It loads PDFs easily and seems to have minimal lag. The main problem is changing pages. Sometimes the next page is off center (as in, only the bottom left quarter of the page is showing) and turning pages is difficult. I just discovered iBooks from apple and I think it works better! Also, it doesnt remember the last thing you viewed when you open it the next time

I bought it specifically to read Harrisons Principles of Internal Medicine 17th and it fails miserably during pre-rendering less than 1000 pages through the process (3352 pages total). This happens both on my iPad 1 and iPhone4.

It has two incomparable features that make reading PDF more pleasurable than any other app out there 1. It pre-renders and thus increases the browsing speed to almost zero response time... Awesome! 2. It can scale pages to screen width regardless of their shape or size...! This is an awesome feature that I could not find in any other app. So you can vertically scroll your PDF as one big continuous page (without trying to adjust the width with pinch or zoom)!!

This is the only app Ive found that will let me handle very large PDFs on my phone. In short, its just what I needed! I can honestly say Id recommend this.

Works great. I can view, print, email on demand right from iPhone or iPad. Very convenient.

The PDF app is by far the best app I have used for PDF documents. It is super fast. I have Blacks Law Dictionary installed and another large unabridged dictionary installed and PDF handles it with perfection. Also, support for PDF is superb. That take their time and really try to give user support in solving any issues. Thanks you guys!

I have tried other apps but there was always a lag in reading large pdf files. Had a few questions on converting a huge 500 page pdf file and received prompt & courteous help from tech support. Now able to easily read this 500 page file. VERY pleased and grateful the developers created this app.
