Is there a work around for this? ### 3/5 — POINTLESS CONVERSION *2022-02-20, version 2.4* It converts but same size as the codec is also changed from h.264 to avc1 ### 1/5 — waste of my time *2022-01-10, version 2.4* This app is a total waste of time and only brings anger and sadness to me because I can’t find any good mp3/mp4 converters and I thought this one would be good, but noooo! Whenever I try to convert a video into an mp4, it says something went wrong! So I decided to shorten the video, and it still didn’t work, so I chose many other different videos and it continued to say “something went wrong”. ### 1/5 — Doesn’t work *2021-11-07, version 2.4* When it saves the export to your camera roll it saves it as a QuickTime video not an MP4. This app is a waste of time. Don’t bother downloading it. ### 3/5 — Works fine *2021-06-30, version 2.4* It’s pretty good, sometimes doesn’t work but that’s fine, but is what I don’t like about it, is that if I have a video cropped or trimmed, in will undo all of that. I could literally be trying to create an edit or something, and spent 30 minutes trying to find the perfect place to trim it so it looks good, and I want it to be an mp4. It will remove all of that and I have to do it again. Developer, if your seeing this, please fix this ### 1/5 — だめだね *2021-04-29* movのままですね おしまい ### 1/5 — Doesnt work *2021-04-24, version 2.4* Cant see videos on camera roll ### 4/5 — I see you *2021-04-07, version 2.4* Aight so it works for me and I don’t have 9401 viruses, plus 720p ain’t bad. Good job on not scamming me for free 🙃 ### 1/5 — doesn’t work *2020-11-22, version 2.4* DONT DOWNLOAD IT DOESNT EVEN WORK AT AL’ ## Most critical reviews (10 lowest-rated) ### 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。 ### 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。 ### 1/5 — Rip off *2023-02-23, version 2.6* Purchased the app to to convert multiple files at the same time. Worked once. Wouldn’t allow me to select multiple files next time I tried. No place to find help to fix the issue ### 1/5 — didn’t work 👍 *2023-01-01, version 2.6* it did not work ### 1/5 — 変換されない保存されない *2022-12-11* エラー　保存に失敗しました 40分ほどかかって変換終わったと思えばエラーで、その原因不明のまま。 ★一つです。 ### 1/5 — Waste of Time *2022-05-19, version 2.6* Well it seemed to work but in the end FAILED… ### 1/5 — 5 Stars to 1 Star - No Longer Functional *2022-05-14, version 2.6* NEW REVIEW The most recent update rendered this app useless. It no longer converts .mov files to .mp4. Instead it runs and seems like it has converted files, but sadly .mov files simply remain in the .mov format. I’m running the most recent version of iOS and using my iPhone 12 Pro Max. I want you to be 5 a Star rated app again, so please look into this matter and/or reply to this review. Thank you! OLD REVIEW Excellent! Quick, Reliable & Easy To Use I gave this a 5 Star rating simply because it performs flawlessly for me. It’s so fast, I bet you’ll wonder if it actually converted your video - I know I did. I had one issue where it was ‘hoarding’ cached data from the .mov files I had converted - but the Developer fixed it very quickly. Highest Recommendation! ### 1/5 — エラーを起こす *2022-04-26* 変換途中でエラーを起こして変換出来ない。ひどい時は数%でエラーを起こす。 ### 1/5 — Not working anymore *2022-03-14, version 2.5* It used to convert to MP4 with no issue. Now it just converts to MOV. What’s the point? ## Most praised reviews (10 highest-rated) ### 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！ ### 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 ❤️ ### 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 ### 5/5 — LIFESAVER *2022-12-20, version 2.6* i never review anything, but this… i had an 8gb mov file that i needed converted to mp4. the file was too large for any program/website to do for free. this app, though, was fast and free. just what i needed :) ### 5/5 — Best and Helpful App *2022-03-24, version 2.6* I had done my shoot but when i transfer videos to pc it shows missing codec bcoz videos are shoot in hevc code than i found this app and convert them into h264 really helpful and working legit.. Highly recommended...!🖤👍🏻 ### 5/5 — これこれ！ *2021-04-06* 超簡単！他のアプリは時間が掛かったりエラーが出たりでまともに変換出来なかったが嘘みたいに早く簡単にmp4に変換出来る。 ### 5/5 — MOV to MP4 *2021-04-04, version 2.4* It did a 4gb file with no problem ### 5/5 — Ok👍🏻 *2020-11-24* Ok👍🏻 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
