Verdict
The most-reviewed app on this list by an enormous margin, and almost nobody has a bad word for it. Point, shoot, and you have a straight, readable PDF.
Best for
Anyone who needs paper turned into a clean PDF and sent onward, repeatedly.
Dealbreaker
It scans and nothing else. No annotating, no signing, no fixing a PDF somebody sent you — for that you need one of the readers below as well.
The facts.
Pulled from the App Store, not written by hand.

Where we recommend it
PDF apps you buy once ›Readers and annotators with no monthly charge.
Alternatives with the same rule.
Every app here is a single purchase. None of them can start charging you monthly for what you already bought. Also with a catch.
$5.99 once · 4.7★ (13,802) · Updated Aug 31, 2026
Verdict. Sixteen years old and still the one people reach for when a PDF is large, awkward or needs marking up rather than just reading.
Best for. Someone working through long documents who wants annotations, folders and a file manager rather than a viewer.
Dealbreaker. You buy it and then it asks again: fourteen of the last two hundred reviews are about a subscription sitting on top of the purchase, mostly to sync files with cloud storage.
$6.99 once · 4.9★ (30,277) · Updated Dec 18, 2020
Verdict. The cheaper scanner, and for most people indistinguishable from the expensive ones. Crisp output, plenty of places to send it.
Best for. Someone who scans occasionally and does not want to spend much on the privilege.
Dealbreaker. Reviewers describe it crashing, and it is scanning only — there is nothing here for reading or marking up the PDFs once you have them.
$199.99 once · 4.8★ (2,942) · Updated Apr 19, 2026
Verdict. A genuinely good scanner with redaction, OCR and a document editor attached, sold as a lifetime unlock of an app that is otherwise a subscription.
Best for. Someone who already knows they want this one and would rather pay once than keep renewing.
Dealbreaker. It is far and away the most expensive app on this site, and six of the last two hundred reviews call the current version unusable. That is a great deal of money to risk on a scanner.
