User reviews

Why do people hate this app so much?

I downloaded the app as a quick fix for a few photos because multiple other apps weren’t working. I submitted a very bad quality photo, and it came out very clean! Yes, it was obvious it was done by Ai, but it was amazing for a bad quality photo. I don’t get why others are complaining. The app is simple, easy to use, and lets you save the image with no water mark. The only thing I wish was improved was the time it took to load. Otherwise, I am grateful for this app, and disappointed it has such a low rating.

Waste of time

I’m always doing photos and graphic’s I ran across this app while searching for something else and decided to give it a try which didn’t turn out very well once you load your image you don’t have any control over what the app does and that would be fine if the app worked like it should but instead of it giving a better quality image it mage it much worse than it was before starting this as far as I know I don’t believe anyone wants to go backwards in the quality department and this app does just that and only that hopefully the developer see this review and others on here with issues and takes care of it I’m constantly looking for new and improved ways to upscale, remove background’s and have yet to find anything that works as it should maybe one day hopefully sooner rather than later I’ll find what I’m looking for

Too bad

I was really excited that someone ported over Real_ESRGAN. Unfortunately, it does not work like the real thing.Every image I tried to upscale turned out blurrier than the original. Hopefully this is just a glitch and the developer will fix!

Amazing!

Huge difference in the quality of the pictures, Keep this app Alive
