Está dando erro e não reconhece os áudios! ### 1/5 — Глючить ваше програма *2021-12-24, version 1.03* Глючить музыка ### 1/5 — Nicht das Geld wert *2021-10-17, version 1.03* Die beschriebenen Funktionen sind gegeben, aber der Klang ist eine pure Katastrophe. Vielleicht liegt’s an meinem iPhone 13 pro. Aber es klingt wie ein defekter Lautsprecher. Habe mich wirklich erschrocken. Es ist definitiv nicht empfehlenswert. mm_aus_n ### 1/5 — Very Frustrated *2019-04-17, version 1.03* This App keeps stopping mid song for no reason. Sometimes it works, other times it stops every few seconds. NOT worth $9.99 ### 1/5 — Save ur $ *2018-09-20* Cuts off in middle of song. Bought to use for dance performances. Boo. Waste of money. ### 1/5 — Terrible! *2017-06-06, version 1.01* Too heavy, too out of sync when using videos no matter on what buffer setting ### 2/5 — A good app but… *2023-07-04* I really like this app, which lets me change the speed and key of a piece of music. However, I find it very incomplete, which is a shame since I paid for it. Here are the improvements I'd like to see: - Being able to listen to music in the background without it bugging all the time - Real management of music detected by the iphone - A new design - Better music management (add music more easily to the app, add album art) - resemble a real music management app, but with independent settings for each track - The ability to create playlists ### 2/5 — Can’t believe this. *2021-10-19* I paid $7 for this app and it’s messing up saying my microphone isn’t set up correctly after only recording like 10-20 something recordings vs the non-pro which didn’t do that but that version has messed up too. Please update this lousy app. PLEASE!!! Why is it saying my microphone isn’t set up correctly when I can record on other apps!!?? ### 2/5 — Fix It! *2020-04-23* Great app if you don’t mind it constantly stopping in the middle of a song. ### 2/5 — Complicated *2019-12-17* 7 dollars gets you any song you want with zero adds. HOWEVER, sound quality does not change in the slightest regardless of which version, inconsistency when switching apps so music may suddenly shut off. Marking system very touchy, and just isn’t worth the price point especially with someone like me who constantly uses it for either practice or casual fun. ## Most praised reviews (6 highest-rated) ### 5/5 — Can you support videos mp4s? *2025-02-08, version 1.03* Tried videos but doesnt suggest the app to open them when sharing ### 5/5 — Fantastic app *2020-04-14, version 1.03* Used primarily for audio, this app is great. Does exactly what it says. Adding songs is a bit cumbersome but I suspect this is an Apple limitation rather than theapp. ### 5/5 — Sehr gut - und es geht noch besser *2019-05-14, version 1.03* Top App für alle, die Musik üben. Für Profis und für Amateure - jeder finden hier intuitiv bedienbare App für Musiker Alltag. Durch Geschwindigkeit Änderung lässt App leicht synchron spielen. Auch schwierige Abschnitte kann man in Loops binden und endlos üben. Tonlage lässt sich leicht transponieren. Es wäre aber besser, wenn die Songs über Playlists sich bewegen lassen - bitte zu nächste Version realisieren. Vielen Dank! PS: App ist jeder Cent Wert! ### 4/5 — Very capable *2019-10-23* I am just trying and have bought this week. I use this to get mp3 files into the right key so I can practice playing and singing music alongside them. I expect I may use the slow down to practice and build up my speed on the guitar as it is totally incremental. The speed up is good to save time when I'm checking the format of songs when I'm writing chordsheets. I really hope that there is work done on making it more user friendly for folks like me and the interface easier to navigate. Haven't got my head around Batch Processing but hope it would do things like being able to save a bunch of files all together in one place rather than individually like I did yesterday just to get it done. Great piece of kit all in one place ### 4/5 — Great App *2018-12-18* Works well for transposing popular songs into my voice range. Easily to use. Compatible with the songs on my iTunes library. ### 3/5 — Нет проигрывания в фоновом режиме. *2021-06-09, version 1.03* Хорошее приложение, но за такую цену очень плохо, что приложение не работает при блокировке экрана. Очень мешает при работе с музыкой. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
