What users say
Pros
- Auto-crop and alignment are accurate: edges come out straight, lines stay parallel and cleaned scans beat plain phone photos.
- Twenty-page delivery notes and receipts scan into a single PDF file, ready to send on the spot.
- Oversized art paper and sketchbooks scan cleanly into legible digital files.
- Handwriting in notebooks converts reliably into editable text.
Cons
- Ads interrupt scanning every few taps and keep appearing after the premium subscription is paid.
- A short free trial turns into a full annual charge, with the renewal warning buried inside the app.
- Scans stored only inside the app, with no account or export, are lost after a reinstall or update.
- Watermarks appear on PDFs from an older paid version, and paid features move behind a subscription.
- Scans upload to the cloud automatically, and the copies cannot be removed afterwards.
