Apparently it creates artifacts when you use the 4x button. Is this something that is being addressed?

i’m going to go ahead and give Smart 5 stars tho in reality it’s probably more like a 4.3. not having access to a computer and in desperate need of enlarging all these wonderful but teeny tiny images i have, i scoured the IOS earth in hopes of finding something. something. everything i tried was garbage and didnt do what was being claimed. then i came across this gave it a try w little expectation and guess what it worked! now i can print my images at a reasonable size and i dont have to worry so much about the resolution output of whatever app i might be using (many of which have a resolution quality that is pretty pathetic, unfortunately). It has its issues, it takes awhile, it crashes out a lot, a couple times i thought it broke my phone when it got stuck in a major fashion .. but eventually it rebooted r whatever and all was well. There is some talk about it creating artifacts, which if u don’t know is seriously difficult issue for digital photography algorithms where they produce flawed spots in the enlargement, blooming, blurred edges here and there. this might be the case here a bit but im satisfied with my enlargements and really just ecstatic i’m finally able to do it. nothings perfect. hope this review helps those on the search.. in my experience it’s legit and worth a try

I originally got this (years ago) for enlarging images. Turns out it’s good for resizing AND for touching up old photos too. It’s great in that it doesn’t reduce the quality of images it processes.

This little gem in the App Store is pretty amazing. Kept digging for something like this to help clear up some of my photos and I have to say it does a really good job. Thanks.
