Ratings and reviews

Good for if you want to make your pictures look worse. Your built-in phone gallery upscaling can interpolate better than this can and you don't need a separate app for it.

it does the job but the thing I'm facing that it's not able to increase the resolution or quality of the pictures that much compared to desktop application named video2x which can actually enhance the quality. thou I'm on moto Edge 60 pro device which have decent chipset, can easily handle this rendering smoothly

I'd prefer the UI to be conformant to Google's M3 Expressive standard however, the app is great in upscaling photos; I just wish it worked on DNG files. When I tried it, the thumbnail only gets upscaled not the RAW data itself, which I presume to be more high quality because of the data present. Anyway, it basically functions like the Google Pixel 10 Pro's Pro Res Zoom. Cheers to on-device upscaling.
