## What is CleanScan?

On-device OCR, full-text search, translation and read-aloud — all free, all offline, no account.

Scan a document and CleanScan turns it into searchable text right on your iPhone. Nothing is uploaded. Nothing is tracked. No subscription, ever.

FREE — ALL OF THIS
- On-device OCR — text is recognised on your iPhone, never sent anywhere
- Full-text search — find any word across every document you have ever scanned
- Searchable PDFs — exported files carry a real text layer, so Files, Mail and Preview can search them too
- Translate — read a scanned page in another language, offline
- Read aloud — listen to any document hands-free
- Shadow removal — flat-field correction erases the shadow your hand casts, so the whole page is evenly lit
- Auto-straighten — edges are detected and the page is de-skewed to a clean rectangle
- Crisp black & white — an adaptive threshold keeps small text sharp while making the background pure white. Colour and Grayscale modes too
- Uniform A4 PDFs — mixed page sizes come out as tidy, consistent pages
- Multi-page — scan, reorder by drag, rename, split, add or remove pages
- QR and barcode scanning
- Live Text and data detection — tap a phone number or address straight from a scan
- Export and share via Mail, Messages, Files, WhatsApp or AirDrop
- Offline history of everything you have scanned, stored only on your device

## Version history (last 5 releases)

### 1.1.3 — 2026-08-05

Faster, lighter, and a lot more honest about what CleanScan can already do.

- Fixed a memory issue that could cause the app to quit while browsing many scanned documents.
- Rebuilt PDF export — large documents are now processed page by page and use far less memory.
- Export now shows page-by-page progress.
- Ads retry automatically after a poor connection instead of staying blank.
- Corrected the privacy wording on the About screen: CleanScan shows non-personalised ads only, never asks to track you, and does not use an advertising identifier.
- Fixed a layout issue on narrow screens.
- Tidied up the tools menu.

### 1.1.2 — 2026-07-19

- Fixed: Sharing now uses the full iOS share sheet — share your scanned PDFs to WhatsApp, WeChat, Mail, Messages, AirDrop, Files, and more.
- Fixed: PDFs are now properly attached when sharing via email.
- Improved error messages when a PDF cannot be created.

### 1.1.1 — 2026-07-16

- Search across all your scans by their text content, including Traditional Chinese, Simplified Chinese, and English.
- Faster saving — documents now save instantly and stay responsive while text recognition runs in the background.
