Short answer
The honest answer depends on the type and severity of blur, and the limits are grounded in physics: blur is an averaging process that destroys image information, and software cannot reconstruct data that was never recorded by the sensor in the first place. AI tools can make blurry images look perceptibly sharper by generating plausible-looking replacements based on patterns from millions of training images — but those added details are the AI's best guess, not a true recovery; on a severely blurred subject they may be simply wrong. Mild motion blur (camera shake during a clear shot) responds best; heavy defocus, extreme motion blur, or low-resolution source images have hard limits no current tool overcomes.
Unblurry helps with this on your iPhone and works on device for privacy — a pay-once app with no subscription. Test it on a real example and check the current App Store listing for details.
What to look for before choosing
- Motion blur (camera shake): more mathematically reversible in theory if the blur direction is known; AI tools help with mild-to-moderate cases
- Out-of-focus/defocus blur: high-frequency detail was never captured by the sensor — AI fills in plausible edges and textures that may not match reality
- Low-res/pixelation: AI generates convincing-looking texture but is inventing detail, not recovering it — the hallucinated pixels may be inaccurate
- Severe blur of any type: no current software reliably recovers it — this is an information-theory limit, not a tech gap that will be closed soon
- Faces and text tend to benefit most from AI enhancement (most training data); unusual objects, fine detail, and text-heavy backgrounds are most prone to AI errors

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. |
