What does SmartScan app do?

Scans docs to PDF with edge detect, OCR text extraction, QR create/scan, edit/sign, all free no ads on Android.

Is SmartScan really 100% free with no watermarks?

Yes – zero ads, no watermarks, no paywalls, open source on GitHub. No account needed.

For most users, yes – fast, accurate enough OCR, multi-page. Lacks polish in UI, Android-only.

Scanning docs without the usual ad hell? One dev built SmartScan – free, open source, no strings. But in a world of freemium traps, can it last?
