The discussion about air pollution in Stuttgart is omnipresent. Located in a kind of pott and high traffic, Stuttgart is one of the cities with the most polluted air in Germany. The city started to roll-out the „Feinstaubalarm“ which is active on days with a specific weather condition which avoids the fresh air supply. During the „Feinstaubalarm“ you get a discount on public transport and car sharing services.
But hey, whats the problem?
The supply of information to the citiziens is lagging. Most of the people dont know why and when the Feinstaubalarm appears. And especially: The strength of the pollution.
What about a service which shows the current strength of pollution in a simple way. The user should understand the current situation at a glance. And of course, get all information around this topic
My first approach.
I started with a very simple website which shows the current value of the main pollutant Nitric Oxide (N02). Beside this small number, the entire viewport will be colored to give an additional expression of the value. To make it more human, i added a smiley which expresses the current value in a mood.
My second approach: lets build an ios app.
After a year of optimizing the website and diving more into this topic I decided to create an iOS App. Since I have have solid Web Development knowledge I would go with the framework React Native.
The final iOS App.
The final App is now available on the iOS App Store.
