Once installed, you can use the app to open PDF files from any other application, including email, that supports the “Open In … ” action. You can also zoom in on text or images and navigate large documents via thumbnails.
As with other PDF applications, you can wirelessly print PDFs from within Adobe Reader using AirPrint. You can also share PDF files with other applications using “Open In…” as well as via an e-mail attachment.
Opening PDF documents with Adobe reader is as simple as tapping your finger. You can swipe up and down OR swipe left and right to change pages.
Compared to similar iOS PDF readers, Adobe Reader is lacking in many features, such as annotation and markup tools as at the time of publishing this post but it is still an industry standard.
