### 1/5 — ios26

*2026-03-26*

エラー発生して使えません。

### 1/5 — パスコードを要求されるので気を付けて

*2025-08-27*

動画変換後に保存をしようとすると、iPhoneの電源を入れた時のような画面が表示されパスコードの入力を求められます。一見はiOSが表示させているように見えますが、このアプリがそれを盗むための擬似表示と思われます。即削除をしましたが、用心してください。
Appleへは「問題を報告する」から「不正行為または詐欺行為」→「プライバシーに関する懸念事項を報告する」を選び通報済みです。

**Developer response:** こんにちは、レビューありがとうございます。
当アプリが独自にパスコード入力画面を表示することは一切ございません。

ご指摘のような挙動が出る原因としては、

1.アプリ内で表示される広告の一部が意図せず誤解を招く表示をしている可能性
2.iOS 18から追加された「アプリごとのパスコード／Face IDを要求する」機能が有効になっている可能性

が考えられます。後者については、ユーザーさまが意図せずオンにしてしまうこともありますので、
iOS自体の設定アプリからご確認いただくか、アプリのアイコンを長押しすることでご確認していたでければと思います。。

当アプリはパスコードやFace IDを盗み取るような仕組みは一切ございませんので、安心してご利用ください。

### 4/5 — ほぼ神

*2025-07-31*

変換するだけならこのアプリが一番いいです！1分くらいの動画が大体30秒で変換完了しました。画質も極度に落ちるというのはなさそうです。ただ、スマホの電源が切れるとエラーが出てしまうので、切れないようにスマホは見張っておく必要があるという点で星4にしました。

### 5/5 — Worked very well and free!

*2025-07-09, version 3.3*

Simple to use and high quality.

### 5/5 — Simple but very functional

*2024-06-03, version 3.0*

This app has a barebones ui, but it is fairly easy to use and does exactly what it says it will do and overall works very well. Simple yet very functional. Fast and nothing overly complicated.

### 5/5 — アイホン　MOVからの変換　Good

*2024-05-17*

有料のソフトばかりの中、変換だけでしたら、
無料で瞬時に問題なく変換できました！

### 3/5 — Is converting an MPG to MP4 possible?

*2024-01-13, version 2.6*

I tried with the possibility that it might convert a .mpg to .mp4, however I think maybe the format is too outdated to convert?

Is there a work around for this?

### 5/5 — It works, and it’s FREE!!!

*2023-10-03, version 2.6*

I do Gothic Dracula inspired rain room scene videos for relaxation on YouTube and TikTok for my channel Missy Moonlight. My video loop was a 1 hour long MOV. All other apps ask for a subscription, this one was FREE and didn’t take as long as I had expected it to. I have already uploaded it for a live video on loop scheduled for later today. Thank you ❤️

### 1/5 — 選択出来ない

*2023-07-12*

トミトルで落とした動画ファイルが一部movpkgというファイル名で保存されていて、
『カメラロールに落とせないので』拡張子を変換したいのてすが、カメラロールから選択か外部アプリから選択、となっております。

外部アプリから選択ですと、〈このiPhone内〉のアプリ名（今回は『トミトル』）の中の当該ファイルなのですが、タイトル名のフォルダとなり

『フォルダ内に更に細かなファイルがある』

と言う状態で、.movpkgファイルが存在するわけではないので選択できません。
どの様に操作すればよろしいのでしょうか。

### 5/5 — What I like

*2023-07-06*

I like that the app does what it says for free and in original quality yessahhh

I also like how it’s a very simple layout 

Only thing I would like is if they would add an option to select multiple at a time

Overall it’s bussin
