This is a fast PDF viewer designed to view large travel map files for Minneapolis. Most PDF software on iPhone cannot handle large files well, they are slow in loading the files and zooming in. Our app is designed from ground up to be a fast reader for large image PDFs. It downloads the PDF from the internet and convert them into smaller image tiles so you can browse it quickly whenver you want. It will process it in the backgroud with the new multi-tasking features in the new iOS.
