Reviews of waifu2x

pretty bad

most of the time when I try to save a video that is over 50 mb it says there is an unknown error

Why doesn’t it tell u that u that u have 2 pay for almost everything

Frm what I have seen the results are really good but everything is paid and it doesn’t tell u that but it’s a good app

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.
