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.

Bubble Calendar is a fresh new way to visualize your schedule as bubbles. Each bubble holds your day. The inner dot represents morning events, the outer dot represents afternoon events. The bigger the bubble, the busier the day. Just type naturally and it recognizes the date and time automatically. Try "Dance class Thu 7:30pm" or "Dentist tomorrow" — it just works. A Monday-first week layout lets you see your entire schedule at a glance.

Verdict
The clearest difference is price: Bubble Days at Free against Echo's $0.99. Bubble Days also leads on update cadence (every 2 days vs every 5 months). Echo's advantage is iOS requirement (9.1 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
