Short answer
Faxes and quick scans often come out soft, so small text is hard to read. A document sharpening mode raises edge contrast on text so letters separate cleanly, and upscaling can add resolution. Unblurry has a document-oriented mode plus sharpen and super-resolution, with a before/after slider so you can confirm it actually improved. Be realistic: mildly soft text sharpens well; a heavily smeared or very low-res scan has limits. It's on-device and pay-once, so the document isn't uploaded.
Try Unblurry on a real example first, and check the current App Store listing for exact features and pricing before you decide.
What to look for before choosing
- Document mode crisps up soft text edges
- Super-resolution can add readable detail
- Before/after slider to confirm the result
- Honest limit: heavily degraded scans recover less
- On-device, pay-once, nothing uploaded
A practical decision process
- Define the job you need done most often.
- Test the app with real content or a realistic scenario.
- Check privacy labels and account requirements.
- Confirm export and backup options.
- Choose the pricing model you are comfortable maintaining.
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. |
