Crispdoc: Document Scanner

A Square Technologies

About this app

Crispdoc turns your phone into a fast, precise document scanner and PDF reader. Point, capture, and get a sharp, searchable PDF in seconds — with a quality score on every page so you know it's right before you save.

ONE SHOT. PERFECT SCAN.
Edges detect automatically, the image is cropped and cleaned, and Crispdoc scores each page for sharpness and lighting. A green score means it's good. A low score means retake — no more discovering a blurry scan after the fact.

BUILT TO BE FAST
Smart camera locks onto the document, multi-page capture keeps a running rail as you shoot, and the moment you tap Save you have a clean PDF. No menus to dig through.
