Short answer
Photos of pages aren't searchable and look skewed; a proper scan straightens each page, removes shadows near the spine, and runs OCR so the text becomes selectable and searchable. ScanTo Pro does this on-device, batches many pages into a single PDF, and keeps everything on your phone unless you export it. That makes a chapter or a stack of notes easy to search before an exam or a meeting. It's pay-once with no account and no watermark.
Try ScanTo Pro on a real example first, and check the current App Store listing for exact features and pricing before you decide.

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
