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. ### 3/5 — Greedy *2025-09-15* 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. (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. ### 5/5 — 神アプリなんだけど *2025-07-02* 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 ### 5/5 — いい感じに写真や画像を綺麗にしてくれる✨ *2025-05-27* 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 ### 5/5 — hmmmm *2025-05-20, version 7.2.7* is there Any Major update soon!? ### 5/5 — Fantastic *2025-05-11, version 7.2.7* Absolutely fantastic app, gets the upscales done with very high quality, especially when used with anime, highly recommend. ### 5/5 — 本当に優秀 *2025-04-06* 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✨️ ### 5/5 — Great App *2025-02-16, version 7.2.7* This app is still awesome! I use it almost every day. It really helps make images look like high-resolution wallpapers! ### 3/5 — 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 *2025-02-04* 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 ### 4/5 — Takes to long *2025-01-31, version 7.2.7* The thing is when I need to edit immediately and I try upscale it annoys me cuz lets me real this thing is better than topaz but it takes just as long so I’m not complaining it’s good but its not perfect ### 5/5 — Love it! *2025-01-16* I encourage you to purchase the complete version. You won’t regret it, excellent definition and quality ### 4/5 — Does a good job *2025-01-05* The app is pretty basic, but does a fair job. Do not expect any AI wonders, but the quality and sharpness are indeed improved after upscaling. ### 4/5 — Great Upscaler *2024-12-21, version 7.2.10* Tinkered around with different presets, it’s a great upscaler for Sims 4 footage, a bargain at £6.99, my only complaint is that it does cause a washed out effect with colour. Support are responsive and helpful, offering solutions. Definitely worth a try. ### 5/5 — Most Excellent. *2024-12-20, version 7.2.10* I think this may be the first review I’ve ever left in my life. As a Product Manager and Developer I have to say … this app is really awesome. Every time I use it I unearth more functionality I didn’t expect to find. - Useful pre-sets & models to choose from. e.g. doubling an image, or upscaling anime video - Quick Access to folders, files and photos. - Support for importing custom models for photos & videos. - macOS companion app If you’re reading this and looking for a “Do one thing well” sort of image/video upscaler, this one is awesome. ### 5/5 — 一直很好用，直到10月份 *2024-11-11, version 7.2.10* Real-CUGAN模型一开始就闪退，iMac Pro（Intel），macOS 15。好像你发布了几个版本都没解决这个问题。 ### 3/5 — フォトブラウザーで利用をしたい *2024-10-25* iOS18・iPadOS18・macOS15の標準フォトブラウザー(写真アプリのUI)で利用をしたいので、フォトブラウザーからの利用を措定して選択できると助かります ### 3/5 — Why doesn’t it tell u that u that u have 2 pay for almost everything *2024-09-21, version 7.2.7* 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 ### 2/5 — 有能 *2024-09-15* あんま変わらんやろと思ったら優秀だった ## Most critical reviews (10 lowest-rated) ### 1/5 — スクロールできなくなった *2025-09-27* 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 **Developer response:** ご報告いただいた問題はこちらでも確認し、現在調査中です。 応急処置となりますが、24時間以内に自動適用される回避策を準備しております。 ご迷惑をおかけしますが、もう少々お待ちいただけますと幸いです。 ### 1/5 — pretty bad *2024-10-13, version 7.2.7* most of the time when I try to save a video that is over 50 mb it says there is an unknown error ### 1/5 — nothing changes *2024-04-14, version 7.2.6* i chose my settings and when the video finishes saving there’s no upscale it’s just the same. ### 1/5 — Not the best *2024-03-27, version 7.2.6* 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. ### 1/5 — 刚刚付费完毕，就又提示要解锁额外模块，什么鬼 *2023-11-29, version 7.2.5* 刚付费完毕$6.99, 隔天再用保存照片就提示要试用模式，要重新付费刚付费完毕$6.99, 隔天再用保存照片就提示要试用模式，要重新付费 ### 1/5 — 入れない方がいい *2023-04-01* なんでこんな評価がいいのかわからない。全部サクラでしょ。絶対入れない方がいい。全然画質変わらなかったし👎 ### 1/5 — Definitely want my money back *2023-02-26, version 6.2.8* Do not use it doesn’t enhance quality of photos or videos ### 1/5 — 소프트웨어가 정상적으로 작동하지 않음 *2023-02-10* KRW 9,900 인앱 결제까지 하고 동영상 업스케일을 시도해봤으나, 처리된 영상들이 모두 100프레임을 넘어가면 멈춘 상태로 끊겨 처리되어 있음. 재시도해봤으나 동일한 증상 발생. 돈과 시간만 날림. ### 1/5 — Too many glitches *2023-01-26, version 6.2.6* I can’t even see the pictures after I try to upscale them ### 1/5 — Rubbish *2022-12-18, version 6.2.6* The completely rubbish app will not allow you to even test it without purchase absolute rubbish avoid ## Most praised reviews (10 highest-rated) ### 5/5 — BEST POSSIBLE IPHONE QUALITY!!!! *2026-06-30, version 7.2.12* 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. ### 5/5 — まとめて高画質化できるのは素晴らしい！ *2026-06-03* 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。 ### 5/5 — ❤️ *2026-05-26* OMGMGMGMG ITS THE BEST APP EVER THANK YOU ### 5/5 — すごく良い！ *2026-04-19* 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！ ### 5/5 — 前はweb版をつかってましたが *2026-01-19* 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。 ### 5/5 — Magic *2026-01-13* This app is awesome ! ### 5/5 — 要望 *2025-10-23* 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。 ### 5/5 — 手軽に高画質化する場合に便利 *2025-10-18* 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。 ### 5/5 — I wish more people knew about this app *2025-07-31, version 7.2.7* 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. ### 5/5 — 最高！ *2025-07-08* 多機能で最高！ 使ってよかった！ --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
