스피킹 연습할때 본인의 발음을 들어보는 것이 중요하다고 하는데, 사실 녹음기 앱들은 많아도 사용하기에 불편한 것들이 많습니다. 다른 녹음기 앱들은 본인의 발음을 연습삼아 녹음하고 들어보기 위해 화면을 잘 보고 녹음, 스톱, 재생, 스톱 버튼을 눌러야 되는데 반해 소개해 드리는 Echo 앱은, 화면의 가운데 동그라미 영역을 누르고 있는 동안 녹음되고 손을 떼는 동시에 곧바로 재생되어 간편하게 연습할 수 있습니다.

The clearest difference is price: arka at Free against Echo's $0.99. arka also leads on update cadence (every 5 days vs every 5 months). Echo's advantage is device support (3 vs 1) and iOS requirement (9.1 vs 17.0). On review sentiment, ads and in-app purchases there is nothing between them.
