"QuickSearch PDF Reader is the tool you didn't realize you needed ... searches are extra fast but it's the interface design that shines ... a terrific app" -- The Unofficial Apple Weblog (tuaw.com) QuickSearch PDF Reader makes it fast and easy to find text in PDF documents. When you add a document, it is scanned in the background, so when you search, results are instant. And as well as searching within a document, you can search across all your documents at once. It’s also a great PDF viewer with a very natural style of navigation. It snaps to page boundaries, yet it’s easy to flick past them. Zooming is straightforward by pinching, or you can double-tap a region of text to zoom to fit. You can easily jump to any part of the document using the scrub bar. And everything is lightning-fast, even on large documents. You can easily get your documents into QuickSearch from other apps on your iPad or iPhone that support the "Open In..." function, such as Mail, Safari, or Dropbox. You can also use iTunes File Sharing to transfer documents to and from your Mac or PC. Full step-by-step instructions are included.

ReceptionRating · Positive reviews · Number of ratings

DG Crews holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: QuickSearch PDF Reader has 24 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of QuickSearch PDF Reader's written reviews are positive against 43% of DG Crews's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

QuickSearch PDF Reader ships an update every 5 weeks, DG Crews every 5 months. Both last shipped on October 4, 2026.
