Paris Air Quality is an app I developed in two weeks.
It simply shows you the current status of air quality in percentage (It is the French standard so don’t ask me what would mean a 100% polluted air!) for Paris and Île-de-France region.

But the cool thing about this app is that first of all it works! (in contrary to the AirParif app with 10m$ budget!! -will write more about that later!-) and secondly the fact that it is based on good UX design, It has a Widget that you can put in your Android home-screen and it will update itself every once in a while without using too much of your cellphone battery! and aesthetically it is very pleasant!

Other features:

• Native Android app (not web-view based like AirParif).
• Has a beautiful and battery-efficient widget.
• beautiful widget designed for your home-screen.
• resizable widget with different layouts for different widget sizes.
• It is completely free.
• It is completely ad-free (No advertising at all).
• Independent development.
• No permissions required except of internet connection! (very secure)
• Available on Google Play, Amazon and other Android Markets.
• Easy to use (Just drop the widget on home-screen and that’s it!).
• Open-Source.

So if you live in mentioned area (Paris and Île-de-France) go check this useful (and honestly must to have!) application on Google-market right away!

If you live in US, Canada or Mexico you can use this app (Air Quality USA) instead (an update for this is scheduled).
