However… *2025-03-14, version 6.2.0* It’s not perfect... When I try and scroll the bar to rewind my songs with, it still crashes and it sends me back to the Home Screen. The good thing is is that it doesn’t crash anywhere near as much as it did before. So there’s always room for a bit of progression! 4/5 ### 2/5 — 動作不安定 *2024-12-28* 細かい耳コピに利用していますが、AB間リピート再生を利用していると、突然数フレーム？のみの「ブルブルブル……」みたい再生をするようになってしまいます。その度に再起動して、AB間の設定もし直さないといけなくてかなり煩わしいです。 このバグが最近は、2分に1回くらい発生するようになったので、ちょっと使い物にならないなーという気持ちになってきています。 **Developer response:** コメントありがとうございます。 Ver.6.2.4 にて、再生中に再生位置を移動させたときにクラッシュすることがある点について対策を施しました。 アップデートしていただき、お試しいただければと思います。 よろしくお願いいたします。 ### 5/5 — Add more things!!!! *2024-01-30* You should add all holiday pitch tones to make it more fun and cool and crazy! Keep it up! ### 5/5 — It doesn’t work *2023-03-20* The only reason I bought this app is to use it as a PLUG-IN on my DAW, but it doesn't work as such, thus losing any sense. ### 5/5 — Gusury *2023-01-26, version 6.0.0* Fudjcjxjx ### 5/5 — Great for tempo and pitch shifts *2022-07-29* It's great for learning dances and tunes. ### 2/5 — The app ideia is good but crash A LOT!!! *2022-07-28* I stop using this app because crash randomly if you press any button on it. You need to pray to use this app for more than 2 minutes without crash and close. When I started to use this app nothing happens, but I don’t know what happened. It looks likethe developers had abandoned the app. Sad. **Developer response:** Thank you for your comment. In the update (Ver.6.2.4), we fixed the issue where the app would crash when you moved the playback position during playback. Please update and try it out. ### 4/5 — 内容はいいけど動作不安定… *2022-06-02* iPhone XS で使ってます 再生位置をスライドで動かそうとしたり、5秒巻き戻ししたりすると、わりと高確率でアプリが落ちます。自分だけでしょうか… それでも落ちたら何度もトライして頑張って使ってるぐらい便利なアプリではあるんですが、、落ちる問題どうにかならないでしょうか？？ **Developer response:** コメントありがとうございます。 Ver.6.2.4 にて、再生中に再生位置を移動させたときにクラッシュすることがある点について対策を施しました。 アップデートしていただき、試していただければと思います。 ### 3/5 — Good but *2022-02-11* After buying the app, it just crashes out of nowhere when I’m playing around with a song. Hopefully the developer will fix this issue in the near future **Developer response:** [Updated] Thank you for your comment. In Ver.5.2.0, the program of the part that causes the crash has been fixed. This has improved on traditional crashes. Please update and try it. ### 5/5 — Great app(with responsive support!) *2020-12-02* Use this app nearly daily for music practice(drums and guitar). When there were issues adding new songs I contacted the dev and the issues were fixed within a week! Highly recommend! ### 2/5 — No English support *2020-09-18* Tried it cant import files **Developer response:** [Update] Updated with the latest version (5.1.1), I fixed the process of loading music files from other app. Please update and check it. ---- Thanks for your comment. This app is created with English as the standard language. However, it seems that it may be displayed in Japanese depending on the state. (It may be a bug in iOS.) Try the following steps. 1. Change iOS setting language to "English" at [Settings]-[General]-[Language & Region]. 2. Change iOS setting language to your language. Thank you. ### 4/5 — Tune Changer *2020-06-06* Great App! Best of a bunch of similar apps. Just needs import of whole albums not just individual tunes. Fab! ### 3/5 — 曲がリストから消える *2019-11-25* アプリ使用中　右下のiPod のプレイリストにない曲がある！ **Developer response:** コメントありがとうございます。説明文にも記載させていただいていますが、システムレベルの点から以下に該当するファイルは本アプリで扱うことができないため、リストにも表示しない仕様とさせていただいております。何卒ご理解いただけますと幸いです。 ・Apple Music, iCloud, iTunes Match 経由のファイル ・デジタル著作権（DRM）で保護されているファイル （iTunes で購入した曲は、DRMで保護されているファイルの場合があります） ## Most critical reviews (10 lowest-rated) ### 1/5 — Not good… *2025-05-22* Whenever I press the rewind button to listen to my songs it crashes. All this time I’ve had this and the developer does nothing to fix it. Deleting it off my phone for a better player! **Developer response:** Thank you for your comment. In the update (Ver.6.2.4), we fixed the issue where the app would crash when you moved the playback position during playback. Please update and try it out. ### 1/5 — Wasted time *2024-05-17* I just wasted my time on this as it will not access my music stored in my system. ### 1/5 — Not as expected *2023-05-20* I thought this was an auv3 plugin that could pitch shift in real time. Wanted to use in AUM. Would like a refund. **Developer response:** Thanks for the message. This is a player app that can be used by adding the auv3 plugin. (not a module) However, I'd like to explore the functionality of modules at some point. This app includes many functions, so I hope you'll try various things. ### 1/5 — Quits out *2022-07-18* Quits out automatically **Developer response:** Thank you for your comment. In the update (Ver.6.2.4), we fixed the issue where the app would crash when you moved the playback position during playback. Please update and try it out. ### 1/5 — UNBELIEVABLE *2022-01-23* I CAN’T BELIEVE THIS! I AM NOT ABLE TO IMPORT NEW FILES! IT JUST SAYS THAT IT FAILED READING THE FILE! AND THE FILE’S TITLE DOESN’T APPEAR! PLEASE FIX THIS! And no restarting the app aint a solution as i’ve done that and it did nothing. **Developer response:** [Update] Updated with the latest version (5.1.1), I fixed the process of loading music files from other app. Please update and check it. ---- If you delete the text file "_play_list.txt" from the standard "Files" app, it'll be solved the problem. Please Try the following: 1. Launch the standard "Files" app. 2. Access　[Browse tab] - [On My iPhone] - [AU Player]. 3. Delete the text file [01_play_list] - [_play_list.txt]. ### 1/5 — This app is not auv3… *2021-09-07* It can load audio plugin effects. That’s all. Plus, you can only load music from iTunes. This is totally useless for me. I could use it if I could load my own samples. Too bad. **Developer response:** [Update] Updated with the latest version (5.1.1), I fixed the process of loading music files from other app. Please update and check it. ---- Please Try the following: 0. Please update this app to the latest version (5.0.0). 1. Launch the standard "Files" app. 2. Access　[Browse tab] - [On My iPhone] - [Your app]. 3. Copy my own samples (audio files). 4. Select a sample. It'll be added the sample (audio file) in the play list. ### 1/5 — Does not support longer files *2015-07-22* Very disappointing n waste of money as the app is not supporting to play full length of the file. Not playing more than 8 minutes. Please don't buy. ### 1/5 — Doesn't function *2015-04-08* Can't even click on options. ### 1/5 — は *2015-03-03* 音割れしてる。 無料以下。 ### 2/5 — Something’s changed… *2026-09-02* I use this app for a while now, but ever since it made an abrupt update it won’t let me play anymore mp3 songs! Had to delete at the end. It’s a shame because I use this app for interacting with the music I play and suddenly goes ahead to do that… **Developer response:** Thank you for your comment. We have confirmed MP3 playback with our test files in version 7.0.3, so we'd like to investigate this compatibility issue further. Please access the support page from the in-app settings screen to contact us. If possible, please provide one affected MP3 file, or a download link to a file you are permitted to share. Please also let us know your device model, OS version, and whether the file was added from the Music library or the Files app. ## Most praised reviews (10 highest-rated) ### 5/5 — Thank you 🙏 *2026-08-28* 👍 ### 5/5 — Custom presets for 31 bands equaliser and custom presets for the reverb effects. *2026-08-03* Thank you for your kind reply 🙏❤️ I can’t wait for your next update for this 😊 **Developer response:** Thank you for your comment. We plan to add a custom preset feature for the 31-band equalizer in the next update. ### 5/5 — Save my own equaliser and reverb settings. *2026-07-07, version 6.2.8* Can you please add the option to save my own equaliser and reverb settings in the presets. Also please add the crossfade playback option. Don’t mind if it is a premium feature but please add it. Thank you so much 🙏😊 ### 5/5 — Save my own equaliser and reverb settings. *2026-06-22* Can you please add the option to save my own equaliser and reverb settings in the presets. Thank you so much 🙏😊 ### 5/5 — Playlist mode? *2026-06-09* Absolutely love the app, I’ve used it for years, would you consider making an option so you could have playlists? It would be nice to be able to organize all the edited songs without having to do workarounds to make new mp3s. ### 5/5 — Super einfach! *2025-12-17* Macht was es soll, sehr übersichtlich und bedienerfreundlich ohne unnötigen Schnickschnack.👍👍👍 Danke ### 5/5 — NICE! *2025-08-12* USA! ### 5/5 — Gusury *2025-04-10* Fudjcjxjx ### 5/5 — Incredible Under-rated Powerful Music App! *2025-01-19* I have been using this app for years and years and I am delighted that it still gets continual updates to increase functionality and improvements! I love listening to my music library at different pitches, and being able to quickly change speeds for gym sessions is also easy with this app. And the music quality remains close to the same instead of a marked downgrade (which is what I found with other apps on the market last I checked). The latest update adds a HUGE feature that makes a big difference for me. The phone now treats the player the same as the Apple music app or Spotify; meaning I can now play and pause a track from the Lock Screen, or even use headphone controls to play, pause, go forwards or go backwards on a track. This is BIG because it means finally the music can be operated on even without being inside the app. If a developer is reading this, the next things that would a make a huge difference to me are a search function, so it’s easier to find tracks within a large library of songs, and a playlist function, so I can create a playlist of songs separate to the main list. Fingers crossed these updates will come one day soon! This app has literally made a massive difference to my quality of life while on the go with my phone. Please accept my heartfelt thanks :) ### 5/5 — Mr Butcher *2024-06-18* I like it best Equalizer in the App Store I have thy them all thanks for making such a good app . --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
