This app can scale and/or denoise images using various advanced on-device AI algorithms. Note that this app is not affiliated with the original waifu2x project.
Privacy is one of the top priorities of this app. Your files will never leave your device to be processed. Additionally, we don't collect any personal information because there are no ADs even if you only use free models. Therefore, if you encounter any problems, please send us a feedback email or create a GitHub issue so that we can work together to fix them.
Try additional models and custom models on your own images for free before you purchase!

Pretty great!
Works pretty great. Lots of options. I bought the additional models.
I would give 5 stars but it uses the old photo picker API that requires me to change the photo library access inconveniently.
Much needed request: please use the PHPicker API instead of the old UIImagePickerController. That way I don't need to expose my full photo library to the app, and I can conveniently select photos without having to constantly change the limited photo library selection in the settings. If you did that this would definitely be a 5 star app, but until then it is a major inconvenience to have to do that.
Amazing.
I use this app to increase the quality of my edits and they look very good, I was trying out the app and I had a very blurry picture where it was pixeled and it came out very clear which was surprising.
Makes ugly things pretty
Would recommend for photo editing & cleaning if you want to go the extra step buy the 6.99 deal & get everything permanently I genuinely recommend it - 0
Great
Best upscaler I’ve ever used
nothing changes
i chose my settings and when the video finishes saving there’s no upscale it’s just the same.
Good
Been using this for a while to improve illustration quality (specifically pjsk cards) and this works good. In fact I jump and joy and shout “yippie yay” when I open this app.
Not the best
I hope the developer release more models for photos. Even the sharpest one isn’t even sharp.. but I paid for it because I can see it improving with future updates!
Keeps crashing and overheating my iPad.
Takes long to load
This is great app I want to use it but why does the upscale take so long
Great upscaling app.
An amazing app
An amazing app, oh my *GOD* it’s /SO/ good!!!!!
I haven’t found any program on any platform that rivals it, it’s so good at what it does and in such a transparent, well-cited way, gosh I love it.
W app
Helped me with many of my edits with the quality. Fasho a good upscale app
