미세먼지란? 우리 눈에 보이지 않을 정도로 가늘고 작은 먼지 입자로 지름 10마이크론 이하의 미세한 먼지(PM, Particulate Matter) 입니다. 이 미세먼지는 사람의 폐포까지 깊숙하게 침투해 각종 호흡기 질환의 직접적인 원인이 되며 우리 몸의 면역 기능을 떨어뜨려 매우 위험합니다. 이 앱은 이러한 미세먼지의 예보 및 행동 요령 등을 미리 알려주어 예방할 수 있도록 제작된 앱입니다. 주요 기능 - CAI, PM2.5, PM10, 오존, 황사 등의 대기 정보를 알려줍니다. - 각 도시별의 미세먼지 농도를 손쉽게 확인할 수 있습니다. - 미세먼지의 실시간 예보를 확인할 수 있습니다. - 미세먼지의 자료를 페이스북, 트위터 등 SNS로 공유할 수 있습니다. - 위젯 기능으로 좀더 쉽게 현재 대기 환경 정보를 확인 할 수 있습니다. - 미세먼지 용어집을 통해 미세먼지에대하여 자세한 정보를 알 수 있습니다. - 오염도에 따라 배경이 달라집니다. ◎ 본 자료는 에어코리아(http://www.airkorea.or.kr)에서 대기질을 실시간으로 예측하여 공개하는 자료이므로 실제 측정 대기 농도와 상이 할 수 있습니다.

Verdict
The clearest difference is ads: PM10º at none against SimpleWeather's shown. PM10º also leads on update cadence (every 10 days vs monthly) and iOS requirement (7.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.
