User Reviews

• “I’ve been using this upscaling tool for about 7 years and never switched to anything else. Most alternatives try to push subscriptions and still deliver results that feel over-processed—or they attempt facial reconstruction that just doesn’t look right. With this app, I bought it once for a few dollars and got permanent access to every model. It’s genuinely refreshing to see something that’s streamlined instead of locked behind constant upsells.”

• “I remember back on iOS 6 it was painful just to browse waifus, but now we can upscale on our phones—sometimes all the way up to 32K. That’s awesome. For serious users, the app is strong even without overwhelming controls: it stays easy to use while still offering enough flexibility, plus it includes helpful ‘casual icons’ for closet weebs. There’s even a folder option for dojin readers—honestly that alone feels worth it.”

• “For a phone app, the speed and capability are impressive. In some cases it even matches or beats what I can do on my high-spec gaming setup with an expensive GPU and costly software. I also like how easy it is to switch between models, and how simple it is to adjust everything. Naming the models based on what they’re best at is a huge help too, especially for users who don’t know the model names.”

• “A few years ago, enlarging an image without losing quality was basically impossible. Now you can do it right on an iPhone. Love it.”
