建設設計図のためLargeViewer

I should have looked at how old the reviews were before I bought this. The app may have performed well at one point in time, but doesn’t seem to be maintained. It was slow to refresh the view of the pdfs I opened and randomly crashes. No bookmark function or markup tools. For a $12 app, I expected to get something that could actually be used.

I been using this app for over a week now. I have large blueprints and USGS maps that have always had been very slow using my iPad and iPhone. Now with this app I can import and viewer faster then I could have ever imagined. The developers are great and thru email are very helpful. I had some very testing plans and prints to very and they helped me with the setting and importing. Great job.

This is a great app for prints. The only thing that needs to change is "tap row to move". You should be able to move multiple rows into a created folder. One at a time is annoying and takes a long time.

I had tried assorted PDF tools before this one and all were extremely frustrating. Large viewer works extremely well and efficiently.

I'm very happy with this app, I use it to view construction drawings, I have more than 1000 sheets in my current project organized as one PDF per discipline. The app handle these big PDFs quicker than my core i7 laptop with acrobat reader. My only problem with this application is that there's no way to make annotations, like in others PDFs apps.

This app is able to open PNG files that are 40,000 by 40,000 pixels or more. Viewing and zooming is extremely fast with no lag. As one other reviewer noted, Large Viewer is probably faster than viewing on a powerful desktop computer. This app works great for viewing huge maps or very large schematics without needing an Internet connection. Additionally, I could see the app being very useful to photographers working with very high resolution photos as the iPad retina display shows details better than most computer monitors. Overall a great app with excellent customer support.

Does as advertised and more. Great for reviewing schematic drawing.

I bought this program with only the slightest hope that it would do what I needed it to do and am very impressed. I had receive a 5 page TIF file from my bank by email and wanted to put my signature on it with my iphone/ipad and just email it back instead of waiting for it to arrive in the mail. I ran out of luck when I realized that the regular Apple ipad email app would only render page 1 out of the 5 page file. The regular ipad email app actually wouldnt even let me open the TIF file in ANY other program (the "open in") function was not even popping up. Fortunately this app "LargeViewer" was able to open and export the full 5 page TIF file from the 1 page photo in my photo album. It even let me save it to a pdf from which I was able to sign it using the SignNow app! Hats off to these guys for making ios so much more functional !

Wow... A great App... Have 2 full sets of construction plans in folders and sub folders... Carry iPad now on site visits, rather than rolls of plans... Also have all RFI's, CCD's, ASI's, all in one folder. Who needs paper anymore. Can print from views to air printer.

"Large Viewer" is still the best large image viewer I have seen, by far. And now with the new iPad with retina display it's even more useful! Simply stunning! If you want to view pretty much any resolution image and really show off what the retina display can do, you've got to get this app! Butter smooth scrolling, and just refuses to crash even when throwing 80-megapixel Phase One IQ180 images at it!
