If I upload several sound files, this all would order them on ways that looked totally random to me. And it seems that I have on way to reorder them. I have upload them literally one by one in order for them to stay in the order that I need them to. For they, I hate this app!!!! ### 3/5 — More precise audio speed options? *2023-12-10* This app is pretty good, however it would be better if the speed options did not change by a twentieth. (1.05, 1.1, 1.15, etc.) Can it be more precise be hundreths? (1.01, 1.02, 1.03, etc.) Or better yet, thousandths! (1.001, 1.002, 1.003, etc.) Thanks! ### 2/5 — Buggy *2022-05-02* This app will only work while I have it open. If I’m listening to an audiobook in my car I have to check the time on the audio, because by the time I get from my garage to my room the app will glitch. I have to delete the whole audio file, upload it from my files again, then use the slider to get to the correct time. This happens at least two times a day. Prepare yourself to be annoyed. Edit: the Wi-Fi file transfer hasn’t worked in weeks. 👎 ### 2/5 — Bad sound *2021-12-29, version 3.3.6* Like the features, but not worth the decline in sound quality. It makes for difficult listening with audiobooks. ### 5/5 — 최고입니다. 그런데 *2021-09-03* 아주 만족하게 7년 계속 사용하고 있습니다 최근 12프로 구입했는데 아래는 제목이 씹히고 위는 거의 붙어서 불편하네요 ### 5/5 — V3.3.4 *2021-08-17* Great app. Whatever they updated just within this week has messed up the app where it doesn’t sit right on the screen. The very top of the app appears at the bottom of your the phone screen. It reminds me of a film slide when you had the film moved up to much and see the top of the film at the bottom of the picture. Makes it hard to select those options that are in the corner of the top of the screen. Please fix it soon. Beside this, I would have a five star rating by me. I’m also giving it a low rating because when you go to the developers website, there is no place to leave any contact information or to tell them any problems being experienced. ### 2/5 — Can’t locate audio files *2021-06-09* I really wanted to like this app, but I can’t import or listen to the audio files that are in my files folder. It finds the music on my phone, but not the recordings of the course that I need to listen to. Even more disappointing is that the help section is completely blank, with no guidance at all. ### 3/5 — Needs a fix *2020-12-17* Used to be a great app so I had to re buy. But the app resets to the beginning of tracks when it’s stopped. Quite annoying. And changing the settings doesn’t save the changes so it always resets. ### 5/5 — The AB repeat does not function properly. *2020-12-17* Thanks for creating this app. But AB repeat do not work well. It repeats several times and then plays from the first of the file or next part itself, even though I didn't touch anything. Please fix this problem. ### 3/5 — Playback speed control good *2020-12-03, version 3.3.3* I just use it to control podcast play speed. Does fine with that. But not intuitive. Hard to figure out the other controls. ### 5/5 — Безупречный ! *2020-07-14* Добавть подробное описание всех пунктов settings пожалуйста . ### 3/5 — Good but Little annoying *2020-06-04* Once speed set for playlist it should play whole playlist at that speed, instead it play first track at set speed and on next track fall back to normal speed. ### 5/5 — Can you release iPad version *2020-06-03, version 3.3.2* Can you release iPad version ## Most critical reviews (10 lowest-rated) ### 1/5 — Not useful *2023-09-25* Won’t give you the ability to vary speed on an entire playlist, as in”play this list of fiddle tunes at 110% speed.” That’s the only reason I tried this. There are much better apps out there to speed up and slow down music on single tracks, which is all this does with sliders that are not very granular. ### 1/5 — Does not work on iPhone Pro 12 *2022-01-12, version 3.3.6* Never wrote a bad review before but this app does not integrate with existing playlists, does not accept valid URLs and has no meaningful support on its site. Very very poor experience. ### 1/5 — 구간 반복 기능이 없네 *2021-03-09* 유료결재햇는데 옛날거보다 훨씬 못하네. 초심을 잃은 것 같아 안타깝네. ### 1/5 — 아이패드에서는 가로가 안되네요 *2021-01-05* 아이패드에서도 똑같이 쓸수있게 업데이트 해주세요 가로로 볼수있게요 ~~ ### 1/5 — 노래가 왜 지맘대로 막 넘어가나요... *2020-11-18* 후기보고 구매했는데 노래는 안나오고 막 넘어가네요 재생버튼도 랙걸리고 ### 1/5 — 언제쯤 고쳐주시나요 *2020-06-29* 구간반복 1-2초 정도 반복 해놓으면 두번 돌아가다 다시 맨 처음으로 돌아가는데 불편해서 못쓰겠어요 ### 1/5 — 너무 후회해요 *2020-05-30* 반복재생도 갑자기 멈추고 느리게 재생도 갑자기 멈추고 이럴거면 이 제품을 왜 다운받는지 모르겠습니다 ### 1/5 — No good ... *2019-12-11, version 3.3.2* This is not working for videos playing on Facebook or YouTube or Vimeo or embedded in websites ... only works for videos stored/ downloaded locally on the mobile ### 1/5 — Fraudulent owner *2019-10-04, version 3.3.2* Delists the app frequently and relists on a different name every few months forcing you to buy again. bought this app again only to leave this review. Don’t buy. ### 1/5 — App ok, but commercial rip off *2018-11-04* The app developer changed, and I was forced to repurchase the app a second time as the original stopped working. ## Most praised reviews (10 highest-rated) ### 5/5 — 使えるアプリ *2026-06-25* abリピートの微調整ができるようにして欲しい ### 5/5 — Life-saver *2026-06-24, version 3.6.0* I’ve listened to thousands of hours of religious content thanks to this app. ### 5/5 — Best app to learn a language *2026-04-14, version 3.6.0* Set the swipes to back and forward ### 5/5 — 리모트 컨트롤기능 좋습니다 *2025-11-18* 어학공부시 리모트 컨트롤 기능 있어서 앞뒤 스킵 가능해서 훌륭합니다 그리고 팝캐스트도 들을수 있고 좋습니다 안드로이드 버젼도 나왔으면 좋겠습니다. ### 5/5 — Excellent ap! *2024-11-30* Love this ap! I use it to improve my knowledge by speeding up the speed that I listen and learn! Impressive technology. Thank you for this excellent ap. ### 5/5 — Thoughtfully designed *2024-06-04* Wow! I wasn’t expecting to be so pleased. The features are very nice, love the extra options in the settings menu. ### 5/5 — Thank god this exists *2023-02-04* It’s super annoying to not be able to customize the speed and rewind settings for most audio player apps that are designed for listening to short audio files. When listening to longer audio files like podcast downloads and courses, this is app is a life saver. ### 5/5 — Best audiobook & podcast player *2022-11-18, version 3.4.1* Wish there was an app for Apple Watch Put a lock on repeat/no repeat ### 5/5 — Great but doesn’t work with Siri *2022-06-23* Great but doesn’t work with Siri ### 5/5 — Only app that meets my specific need *2021-10-29* I use the touch controls on this app to help memorize material. It’s the only app I’m aware of which lets me touch the screen to pause/resume, swipe to skip/rewind, and even touch to speed up/slow down. I can do all of this without looking at the phone. The only downside is that the latest update seemed to break the ability to play files on Dropbox. I have a workaround where I can find the app in Dropbox and then export to SpeedUp so it’s not a showstopper for me. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
