BEST POSSIBLE IPHONE QUALITY!!!!

Honestly I am very impressed! I have been using this for about 2 years and honestly I have never used a better quality upscale. It’s like 8k but on mobile devices. I am so thankful for this app.

まとめて高画質化できるのは素晴らしい!

高画質化したい画像が大量にある時に、一遍にまとめて高画質化できるのは最高です。
他の画質向上アプリでは一遍に高画質化はできません。
広告が無いのも素晴らしい限りです。
いずれ有料プランに課金してみようと思います。

OMGMGMGMG ITS THE BEST APP EVER THANK YOU

すごく良い!

画質が悪かったりする画像を加工して即座に解像度も良くて良いものにしてくれて無料なのがとても素晴らしい!今の所良い点しか無い!

前はweb版をつかってましたが

アプリになっていたのですね。
2倍に拡大するのにあっという間でした。きれいだし
すごい。

Magic

This app is awesome !

要望

ショートカットと組み合わせて使っています。
もし可能なら「画像読み込み→変換(固定された設定)→アルバムに保存」をノンストップに実行できるようにしてほしいです。

手軽に高画質化する場合に便利

複数の画像をまとめて高画質化する場合は重宝します。バックグラウンド動作に対応していないけれどその短所を差し引いても使えます。ただしiPhone8のような古い端末では遅くなるので素直に新しい端末に変えることをお勧めします。

スクロールできなくなった

画像選択時にスクロールできない
スクロールできても選択した画像の順番がめちゃくちゃになるんですが

Greedy

Greedy dev, charging for features free in the version they ripped and called their own. Super entitled in their dev replies, maybe if they weren’t I’d consider supporting it anyway lol. Dev is charging you a convenience fee for something that’s free. If you don’t mind that, it technically works. Speed is ok but that’s by no fault of the “magic” since again this is repackaged FOSS. (not to take away from the effort they put into this gui, they did do work). $7 if you want to use any real upscaling model. Worth it perhaps, but in my opinion the M chips just aren’t fast enough to justify charging for it.

Edit: I’ve softened my stance a little. I paid the $7 more out of curiosity than anything. It’s still not worth it. The models are good and it does work, speed is…. Fine, unimpressive (m4, but on an air). I wish I had realized that unlike waifu2x proper, there is no interpolation here.

Now honestly, that’s more inconvenient than disappointing. Part of why my stance has softened is that getting waifu2x or any upscale (gan models etc) is a pain in the neck on Mac. They’re also highly unstable so, this does get points for so far having been very stable.

The lack of rife/interpolation is less of an issue because I’ve not had an issue using interpolation software on Mac like I have video upscalers. Your other options would be software that cost $100 or more typically. So for $7 as a convenience fee? Meh. It’s fine. Slow, but acceptable as I’ve said, but god it is slow (if you know, you know, these scalers are always glacial even on proper GPUs)… but fine. Ram usage is good, description doesn’t lie about it being optimized.

I do however think that charging extra to use custom models is still a bit greedy. Why charge? No reason but $$$ Whatever though, dev is allowed to earn their bread too.

Greedy

Greedy dev, charging for features free in the version they ripped and called their own. Super entitled in their dev replies, maybe if they weren’t such a git I’d consider supporting it anyway lol. Just download waifu2x from GitHub yourself. Dev is charging you a convenience fee for something that’s free. If you don’t mind that, it technically works. Speed is acceptable but that’s by no fault of the dev since again this is repackaged open source software.

I wish more people knew about this app

I've been using this little side branch of upscaling for probably over 7 years now, never used anything else. Everything else follows this nauseating standard/framework of being loaded to the brim with ads, begging the user to enter a subscription model, and yet still gives poor outputs that are usually way over processed or try to do that terrible facial reconstruction.

Yet with this app I literally make a one time, few dollar purchase and have full access to every model permanently.

It's extremely refreshing to find something that was actually streamlined properly.

最高!

多機能で最高!
使ってよかった!

神アプリなんだけど

追加して欲しい機能

高画質化しない部分を選べる機能
具体的にいうと、髪の毛などの細かい部分は拡大してしまうとふわふわ感が無くなって逆に劣化するので塗りつぶしたところは加工されない、と言った機能

生成したデフォルトの画像名が長すぎるので自分で設定できる機能

いい感じに写真や画像を綺麗にしてくれる✨

綺麗にしたいなぁって思う画像やイラストをこのアプリにかけてあげると、限界はありますがいい感じに綺麗にしてくれるのでいつも愛用してます(ノ˶>ᗜ​<˵)ノ‪☆彡‬✨
そして元々 綺麗でこのアプリにかける必要がない画像やイラストも、もっといい感じに綺麗になったりするので、綺麗な画像やイラストにあえてこのアプリをかけてあげるのもおすすめ│ ˶^ᵕ^˶)b✨

まぁ想定されてないのかもしれないけれど、外で撮った写真とかを綺麗にするのはあんまり得意じゃない感じかな

hmmmm

is there Any Major update soon!?

Fantastic

Absolutely fantastic app, gets the upscales done with very high quality, especially when used with anime, highly recommend.

本当に優秀

アニメだけじゃなく、モンハンの様なssの粗さも認知して綺麗に整えてくれる✨
重宝してます!出会えて良かった✨️

Great App

This app is still awesome! I use it almost every day. It really helps make images look like high-resolution wallpapers!

最高に素晴らしいアプリですがiOS18のアルバムのコレクションから選べると便利

素晴らしいアプリですがアルバムから選ぶ際にひとつ改善点があります。
現状だと全てのアルバムが選べないので、
iOS18になった際の「アルバムコレクション」からのUIから選択出来るようになると助かります。
またはクリップボードからの張り付けにも対応してくれると助かります💕
改善よろしくお願いします
