Short answer
General sharpening (the Sharpness slider in Photos or a basic editor) only strengthens edges that are already there, so it does little for a genuinely out-of-focus or motion-blurred shot. Purpose-built repair apps apply targeted processing — deblur, denoise, low-light recovery — for each kind of problem. On privacy: many online unblur tools require uploading your photo. Unblurry runs entirely on your iPhone with no cloud and no account, and offers several dedicated modes (Auto Clear, Sharpen, Denoise, Low Light and more) for different blur types, as a one-time purchase. No app can perfectly rebuild a badly blurred photo, but a dedicated on-device tool gives soft, shaky and low-light shots the best realistic chance.
Try Unblurry 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. |
