### 2/5 — なんだこりゃ

*2026-07-28*

3回目までは良く、そのあと、シャットダウンばかり。

### 5/5 — WOW!!!!

*2025-10-25*

This app is fantastic! Use it all the time!

### 5/5 — Great local ESRGAN upscaler for iOS

*2025-09-08*

This works great locally on my iPhone. And what’s most important is that it is not held back by any in-app purchases (unlike that other upscaling app, waifu2x).

One thing I do wish for is to be able to import other models off of the OpenModelDB, or at least the converted ones from that other app. Being able to use those more refined models over the original trained models would be a plus.

### 1/5 — は？

最初はできててよかったけど、最近使うと処理したら落ちるゴミ🗑️
