### 1/5 — 金返して

*2026-08-12*

とにかく金返して

### 1/5 — 、絶対にダウンロードしてはいけません

*2026-07-25*

気がつかないほうも悪かったのですが、知らない間にインストールされており、1週間に1500円ずつ課金されています。非常に残念なことに半年間気がつきませんでした。1ヵ月約6000円の損害です。サブスクは常にチェックしないとダメですね。勉強になりました。

### 1/5 — Useless app

*2026-07-18*

Don’t download. there’s better apps that do the same and don’t act like a brick wall

### 1/5 — 気をつけて下さい

*2026-06-24*

勝手に登録されて毎週¥1,500自動引落されてて、気付かずに半年間で¥60,000以上引落されていました！返金請求したが勿論無視です、最悪なサブスクです！

**Developer response:** この度はご不快な思いをおかけし、大変申し訳ございません。半年間気づかないまま課金が続いていたとのこと、重く受け止めております。なお、App Storeの返金につきましては、開発者側では手続きができず、すべてApple側で対応しております。お手数ですが、Appleの「問題を報告する（Report a Problem）」のページよりご申請ください。過去の請求分もまとめて申請でき、こちらが最も確実な方法です。料金や解約方法の表示が分かりづらかったとのご指摘は真摯に受け止め、改善に努めてまいります。

### 1/5 — 詐欺アプリです！！！！

*2026-06-23*

QRコードリーダーアプリから悪質な見た目の広告からダウンロードするハメになりました。
勝手にサブスクリプションを登録することになるので注意です！！！！！

**Developer response:** ご報告ありがとうございます。広告から誤解を招く形でダウンロードに至ってしまったとのこと、大変申し訳ございません。当社はそのような広告掲載を意図しておらず、問題のある掲載は特定し次第停止したいと考えております。差し支えなければ、アプリ内のサポートより、どのアプリ・サイトでその広告をご覧になったかをお知らせいただけますと、調査のうえ不適切な広告の削除に努めます。なお本アプリは無料トライアル付きのサブスクリプションで、期間終了前に解約いただければ料金は発生しません。解約は［設定］＞［Apple ID］＞［サブスクリプション］から可能です。ご不便をおかけし申し訳ございません。

### 1/5 — 詐欺に注意！

*2026-06-21*

カラオケのドリンク注文時にQRを読んだら勝手にサブスク登録され、3日後に3,000円の請求がきてビックリ！すぐにサブスクをキャンセルし、Appleに返金申請して認めてもらえました。
ってか、週3,000円とかふざけてる！店とグル？何なんだコレは…。気づいたらすぐに対処してください。注意！！

**Developer response:** ご報告いただきありがとうございます。混乱を招いてしまい大変申し訳ございませんでした。返金が無事に認められたとのこと、まずは安心いたしました。店舗のQRから本アプリに誘導されたとのことですが、当社は店舗と提携しておらず、そのような誘導は意図しておりません。どのような経緯でQRから本アプリに至ったか、差し支えなければアプリ内サポートよりお知らせいただけますと、問題のある広告・誘導を特定し停止に努めます。なお本アプリは無料トライアル付きで、期間終了前に解約いただければ料金は発生しない仕組みです。料金や登録の流れが分かりづらかったとのご指摘は重く受け止め、改善してまいります。

### 1/5 — 詐欺注意！

*2026-06-20*

いつも使っているQRコードアプリを使用したところ、読み取ったサイトに行かずにこちらに先導されました。いつものアプリが使えなくなって、アップデートしなくては行けないのかと思いダウンロードしましたが、3日無料、週額1,500円の表記がありすぐに削除。こんな詐欺が増えてくるのかなと怖さを感じます。皆さん気をつけてください。Appleの方でも対応してほしいです。

**Developer response:** ご報告ありがとうございます。お使いのQRアプリから、読み取り先のサイトではなく本アプリへ誘導されたとのこと、大変申し訳ございません。なお、当社では「アップデートが必要」といった内容の広告は一切出しておりません。そのため、第三者が当社と無関係にそのような表示を行っている可能性があり、当社としても問題のある誘導を特定し停止したいと考えております。差し支えなければ、どのQRアプリをご利用中にこの表示が出たか、アプリ内サポートよりお知らせいただけますと調査の手がかりになります。料金（3日間無料・週額1,500円）の表示にお気づきいただけたとのことですが、誘導の経緯が分かりづらく不安を与えてしまった点を重く受け止め、改善に努めてまいります。

### 1/5 — Wrongly charged

*2026-06-16*

This developer charged to my account $9.99 for resubscribed before the free trial ended and I had already cancelled my subscription before the due date to be charged. I DID NOT RESUBSCRIBE. They denied my request for a refund and denied the review, reporting it ineligible for refund and decision final. The receipt is showing that I been cancelled my subscription and was still charged. Don’t bother. This app takes money from people and refuses refunds

### 1/5 — 最悪なアプリ

*2026-06-07*

1週間ごとのサブスクとなっており課金されるのでくれぐれも留意下さい。

**Developer response:** ご留意いただきありがとうございます。ご認識のとおり、本アプリは週単位のサブスクリプションです。無料トライアル付きで、期間終了前に解約いただければ料金は発生しません。また、より割安な年額プランもご用意しております。解約・プラン変更は［設定］＞［Apple ID］＞［サブスクリプション］からいつでも可能です。料金体系が分かりやすく伝わるよう、表示の改善にも努めてまいります。

### 1/5 — 結構怖いアプリです

*2026-06-02*

気づいたら毎週1500円の引き落としがされます
サブスクリプションで引き落としを止めれます

**Developer response:** ご報告ありがとうございます。気づかないうちに課金されてしまったとのこと、ご不安をおかけし申し訳ございません。ご案内いただいているとおり、課金は［設定］＞［Apple ID］＞［サブスクリプション］からいつでも停止できます。本アプリは無料トライアル付きで、期間終了前に解約いただければ料金は発生しません。トライアルや更新のタイミングが分かりづらいとのご指摘は重く受け止め、表示の改善に努めてまいります。
