The app does make changes . Smoothness works all the time. I find AY face restoration smooth pics better , but the face is a bit artificial, unreal. The examples given with the app are all work great, but on my own photos it is miss and fail to get the same result. As i said my photos get better but mostly not as good as the app’s examples or in the app’s website. I failed to get the similar results advertised in the website. Either it is with the white grains – too sharp or just a bit smoother. To change 1 pic takes a minute or 2. the tick in START UP NEXT TIME – doesnt do anything . it takes the same amount of time (long) if you change the pic, or the settings. maybe it means if i changed 1 time then getting back to the same settings of the photo i just used will not redo the process from the scratch – then yes it does work . also dont upgrade it. i tried for the offered 3.3 version and the app was unregistered. so i reinstalled back to SOS version.
