eSign: The Difference Between Viewing A PDF And Actually Signing One

Most document apps installed on a phone handle viewing, zooming, and maybe annotating a PDF. Actually placing a legally usable signature on it -- and exporting a file a client can open without complaints -- is a narrower category, and it splits apps that look similar on a store listing into two very different tools.

eSign processes PDF, DOCX, image, and scanned documents entirely on the device, with no cloud upload step between opening the file and signing it. That matters most somewhere with no signal at all -- the app works fully offline, so a job site or a moving vehicle never blocks a signature. Pages can be cropped, rotated, and reordered before the signature goes on, and export resolution goes up to 300 DPI.

The footprint is just over sixty megabytes, it runs on iPhone, iPad, iPod touch, Apple Silicon Mac, and Apple Vision, and signatures stay local rather than routing through a third-party server. The full toolset stays available on the free tier, with a three-day trial covering the premium export options.

None of that explains what happened on the app she tried with six minutes left on the clock -- read the full breakdown here.
