Smog Lite

A modern, automatic air quality check application

Smog Lite performs an automatic air quality analysis so you don't have to.

No knowledge of the specifics of the Polish air quality monitoring is required. Smog Lite will automatically apply the knowledge in the analysis and give you clear results while dealing with all the caveats under the hood.

The results are presented in a simple, readable way requiring no smog-expertise to understand. For example: "good", "bad" or "moderate".

Smog Lite uses data from measurement stations of the Chief Inspectorate Of Environmental Protection located within 10 km radius around you and covering up to 7 distinct types of air pollution, depending on the area.

Simplicity:

There is one setting - the threshold level of air quality triggering warning notifications.

Battery efficiency:

Smog Lite exercises great care in using your phone's battery. Passive location method is used whenever possible. Air quality updates scheduling is properly delegated to the operating system, allowing to group similar requests together, thus saving power on radio wake-ups as well as the general device wake-ups.

Color-wise the app is optimized for AMOLED displays in order to further facilitate great battery life.

When smog notifications are turned off, the app never runs in the background, thus consuming no energy at all.

Security:

Smog Lite is connecting directly to the official servers of the Chief Inspectorate Of Environmental Protection. Servers are authenticated and all of the communication is encrypted.

Technical details:

The app doesn't show you the raw data downloaded from the server, instead it performs the entire analysis itself based on it and only displays the end result. In order to analyse the data Smog Lite combines the air quality measurement stations around you into a single virtual station by collecting individual pollutants' data from these stations as needed. The final verdict is the highest sub-index for an individual pollutant on the virtual station.

When any of the expected types of air pollution isn't covered, the app considers it a data shortage. If at least the seasonal key pollutants are covered, it displays likely air quality with a comment on the missing data and its significance.
