### 5/5 — 裏ワザ笑

*2026-04-04, version 1.2.3*

旧を長年使用してます。プラスに全てをカメラロール経由で保存すれば機種変更する時に超楽チンです！
プラスはiPhone端末に直捨保存してくれるし、もちろんiCloudにも対応している。だから KING BOXにデータ移行するよりプラスに移行してる。もちろん新規はKING BOXだけどね笑

### 1/5 — 何だこれ？

*2026-01-15, version 1.2.3*

なにこのクソアプリ、
何一つまともに機能しないんだけど。

### 5/5 — 音楽ダウンロードできない皆さんへ

*2025-07-03, version 1.2.3*

本来このアプリはサービス終了を既にしています。公式が発表しています。何故か消えてはいませんが
これの代用アプリとしてトルミルというものがあるので同じアプリが欲しい方はそちらをダウンロードしてください

### 1/5 — 保存できない

*2025-06-15, version 1.2.3*

YouTube無理です🥺

### 1/5 — いよいよ御役御免か

*2025-04-16*

iPhoneにはyoutubeの広告を消せるアプリが少なく、低画質ながら広告なしで見れるアプリとして重宝したがPC経由でもyoutubeshortsを消せなくなった。低画質+ライブチャット不可等の多大なデメリットに加えて前からずっと修正されない横画面でスワイプするとハングアップするバグも治らず擁護も苦しい状況。
トルミル()はお察しなのでshortsバグが治らなければ別れの言葉を書き込む事になりそう

### 1/5 — 保存ができない

### 2/5 — YouTubeからの保存ができない

*2024-08-30, version 1.2.3*

前使ってた時は「are you ok?」を押せば保存できてましたが今は押してもなんの反応も起きません

どういうことですか。

### 5/5 — バーコード

これずっと愛用してます！
まじで文句なしの5評価
