EasyScan Document & Book Scanner — Feature Guide

New here?

Point at a page,
get a flat scan

EasyScan finds the edges of a document live in the camera, snaps at the right moment, and hands back a flat, clean, shadow-free page — even from a curved book. Everything runs on your iPhone; nothing is ever uploaded.

01 Live detection

The frame finds the page, not the other way around

As you aim the camera, EasyScan detects the document boundary in real time and steadies it with motion smoothing, so the outline doesn't jitter in your hand. Hold still for a moment and the outline turns green — then the shutter fires by itself. You can always tap to shoot manually, too.

Detect
Real-time

On-device vision finds the four corners of the page in every frame.

Stabilize
No jitter

Frames are blended so the outline stays calm even with shaky hands.

Capture
Auto

Steady + confident = an automatic, full-resolution capture with haptic feedback.

Too dark, or moving too fast? The app warns you before you waste a shot — a low-light and blur check runs alongside detection.
02 The pipeline

From a photo of a page to a page

A photographed document is a trapezoid with shadows on a desk. Every capture flows through the same on-device pipeline that turns it back into the page itself.

03 Book Scan

Curved pages come out straight

Photographing an open book bends every line of text toward the spine. In Book mode, a neural network traces the page's curved surface live in the viewfinder, picks the page you're aiming at (fold-split, so the opposite page stays out), and flattens the curl — not just the perspective.

See it before you save it

The curved boundary you see at capture is exactly what gets flattened — what you see is what you scan. On the result screen, a Before / After button flips between the original and the uncurled page so you can judge the fix instantly.

Works offline, like everything else

The dewarp network ships inside the app and runs on the Neural Engine. No page ever leaves your phone.

04 Clean-up

Shadows lift off, ink stays black

Phone scans usually carry your own shadow. EasyScan estimates the lighting across the page and divides it out, leaving even, paper-white background. Brightness works like camera exposure — the paper gets brighter while the text stays dark and crisp — plus contrast and sharpness, all with a live preview.

Three output styles

Color keeps the document as-is. Grayscale drops the color cast. B&W thresholds to pure black-on-white — the "clean photocopy" look that prints beautifully.

Your last settings are remembered and applied to the next scan automatically — including multi-page batches — and one tap resets everything to defaults.

05 Multi-page

Ten pages, one PDF

Switch on multi-page mode and keep shooting — each capture lands in a growing batch. Review the thumbnails, drop the misfires, then export the whole set as one merged PDF or save the pages individually to your gallery.

Built for contracts and handouts

The page counter stays on screen while you shoot, every page runs through the same flatten-and-clean pipeline with your saved settings, and the PDF is named and dated for you — ready to send.

06 Save & share

Your scans, wherever they need to go

In-app gallery

Every saved scan lives in the home gallery — view it full-screen, rename it, share it again, or delete it.

JPEG · PNG · PDF

Pick the format at save time. Single scans export as an image or one-page PDF; batches merge into one document.

Share sheet

Send straight to Messages, Mail, AirDrop, Files, or any app — the standard iOS share sheet, one tap away.

07 Free & Pro

Pay once — or don't pay at all

EasyScan is free to use: you get a batch of 5 free scans, and when it runs out, watching one short ad refills the batch. Prefer zero interruptions? Pro is a single one-time purchase — no subscription, ever.

Free
with ads
5 scans / batch

Full scanning pipeline, book mode, multi-page PDF — everything works. A small banner shows on the home screen, and an optional rewarded ad refills your scan batch when it's used up.

Pro
one-time purchase
$4.99 once

Unlimited scans and every ad removed, forever. Bought it on another device? "Restore Purchases" brings it back — it's tied to your Apple ID, not the phone.

No account, no sign-up, no subscription. If an ad ever fails to load, scanning is never blocked — the app lets you through.
08 Privacy

Your documents never leave your phone

100% on-device

Detection, flattening, book dewarp, and clean-up all run locally — in airplane mode, if you like.

No uploads, no account

Scans are stored only in the app's own folder on your phone, and shared only when you tap share.

Non-personalized ads

The free tier shows ads requested in non-personalized mode — no ad tracking prompt, no cross-app profile.

09 Thirty seconds is all it takes

Getting started

Lay the page down, tap Scan

Any reasonably flat surface works. Contrasting backgrounds (dark desk, white paper) detect fastest.

Hold steady until the outline turns green

The shutter fires by itself. Scanning a book? Tap the book icon first and aim at one page.

Check the corners, then the clean-up

Drag any corner to fine-tune the crop, then adjust brightness or switch to B&W on the preview screen.

Save or share

Keep it in the gallery, or send it off as JPEG, PNG, or PDF. Multi-page batches merge into a single PDF.
