I don't know how to use the manual mode. Neither does anyone else, probability including the author; but in auto-mode, this app does a magnificent job of sharpening. I don't know what algorithm it uses but it out performs all the high-end Android photo apps, and believe me, I've bought all the paid ones and installed the free ones.
This app helped me read text of a blured photo I took. Not perfectly, but just enough to make out most of what it read. The resulting image was still a bad image but it was a little better than before,
Lots of option but just simply an image sharpener. No real magic debluring algorithm going on here. !SCAM ALERT!
Great app, works well. It became even faster and easy to use after update
If I could give -200 stars I would... I This does not work!!!!
Just waste my money.... Its just adjust the contrast
* Improved speed and stability
