### 5/5 — 간단하고 직관적입니다

*2022-06-04, version 1.1.3*

장점
1. 간편하고 직관적 입니다.
2. 영화중 명대사가 있어서 미관상 더 좋습니다.
3. 무료입니다!!
4. 단조로운 제목 보다는 영화제목으로 해서 더욱 흥미를 자아냅니다.

바라는 점
1. 공간음 중에 중간에 "틱"하는 소리가 있는데, 아마 loop음을 쓰는것 같습니다. 그 부분이 개선이 되면 더욱 좋을 것 같습니다. 블러처리라든지...
2. 옵션 중에 영어 대사를 한글로 출력하는 부분이 있다면 어떨까요?
3. 전체 보다는 "장르"를 기본화면으로 둔다면 "이 소리는 이거구나"를 알 수 있지 않을까 합니다.

하지만 바라는 점은 1번을 제외한다면 극히 개인적이고, 장점이 너무나도 압도적이어서, 이 앱을 적극 추천합니다!

### 5/5 — 좋아요

*2022-01-31, version 1.1.3*

심플하고 소리도 너무 좋음
