### 5/5 — 유선 이어폰 연결 시 재생 안됨

*2026-05-24*

애플 정품 이어팟 usb-c type 연결 시 재생이 안돼요. 너무 잘 쓰고 있는 앱이라서 다른 앱 쓰고 싶진 않아요. 이 문제를 해결해 주세요. 제발

### 1/5 — No timer

*2026-02-08*

One star for the bugs, no color label list, and no sleep timer like the android version. I give you 5 stars if you fix this error..

### 5/5 — Add Downloading

*2025-11-25*

This is an amazing app, with it being able to change pitches if the song and the tempo. However, I think there should be a place to download the songs after changing the pitch and tempo.

### 5/5 — 유료결제로 광고 제거가 가능하면 좋겠어요🫠

*2025-11-16*

너무 잘 쓰고 있는데 광고 때문에 다른 어플로 갈아탔었거든요... 근데도 다시 돌아왔는데 🥺 유료결제 하고 광고 제거 되면 좋겠습니다 !!!! 돈 낼게요!!!!!!!

### 5/5 — 🌟

*2025-10-06, version 1.4.5*

Работает! Спасибо! 🙏🏻

### 1/5 — No timer

*2025-08-24*

One star for no sleep timer like the android version. I give you 5 stars if you fix this error.

### 5/5 — 몇 개만 업데이트 부탁드려요!!!

*2025-07-12, version 1.4.5*

토익 공부하는데 너무 너무 잘 활용하고 있습니다!! 몇 개 업데이트만 해주심 너무 편리할거 같아요…. 

1. 파일이름 겹쳐도 구분되게 하기

파일이름이 같으면 새로 다운로드 받은게 그 전꺼랑 같은 파일이 되어버려서 곤란해요,,,

2. 스플릿뷰 지원

어학 공부 시 대체로 pdf파일을 아이패드에서 동시에 봐야하는 경우가 많은데 스플릿뷰나 플로팅 기능이 전혀 없어서 너무 아쉽습니다. 멀티 윈도우로 하고는 있지만 다른 창을 다시 사용할때는 두 번 클릭해야하는 불편함이 있어요.

3. 여러 파일 한 번에 업로드

여러 파일을 업로드할때 동시에 올리지 못하니 여러번 반복해서 하게 되는데 너무 불편하네요 ㅜㅜ

무료인건 알지만 요 점들 보완하면 완벽한 앱이 될거 같습니다!

4. 아이튠즈 칸은 따로 빼주시는게 좋을거 같아요. 파일 앱 들어갈때 실수로 누르면 또 로딩시간이 길더라고요 ㅜㅜ

### 5/5 — GOOD

*2025-03-16, version 1.4.5*

GOOD

### 5/5 — 음질을 더 좋게 해주네요

*2024-09-10, version 1.4.4*

귀에 쾌감이 옵니다.

### 4/5 — Норм

*2024-07-23, version 1.4.4*

Еслиб сохранялись настройки определенной песни было бы славно
