PM10º - Air Pollution Forecast is a free iPhone application developed by Young Sung Lee. It falls under the lifestyle category, specifically in the subcategory of weather. This app provides users with information and forecasts about fine dust particles, also known as PM10, which are invisible to the naked eye and have a diameter of 10 micrometers or less.

Fine dust particles can deeply penetrate our respiratory system, causing various respiratory diseases and compromising our immune system. PM10º aims to help users prevent such health risks by providing them with forecasts and guidelines on how to take appropriate actions.

The main features of PM10º include providing information on CAI (Comprehensive Air Quality Index), PM2.5 and PM10 levels, ozone levels, and yellow dust. Users can easily check the fine dust concentration in different cities and access real-time forecasts. The app also allows users to share air pollution data on social media platforms like Facebook and Twitter. Additionally, there is a widget feature for convenient access to current air quality information and a glossary of terms related to fine dust particles.
