► Here’s what satisfied users around the world are saying about LargeViewer:

"Keep up the good work. You have an excellent program. All of our field staff have iPads and the number one complaint is slow rendering when reading blueprints. I will let everyone know to try this app and re-evaluate their position on digital blueprints.” 

"Finally! This is the viewer that handles any size image I throw at it. Even ones with many dozens of megapixels! I have been looking for something like this. Others I have tried are extremely slow at scrolling or zooming, or can't handle the large images I want to view. But LargeViewer is screaming fast and can handle ever size image I have tried."

"LargeViewer is 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!”

"I am a professional civil engineer. I now have all my drawings loaded to my iPad when I go for inspections. It works well for large files and it is FAST."

"Incredible. Test passed with a TIFF file from 11.000 x 5700, weight 190 MB. Fantastic. It has a button to zoom to 100%, and it’s easy to go beyond the resolution of the file. Thanks and congratulations for the work. App absolutely recommended.”

Get field app

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.

Great app

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.

Opened a 5pg TIF file from my photo album !

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 !
