Doesn’t work
Tried to use it to route me somewhere and it kept saying “the data couldn’t be read because it isn’t in the correct format.” It did this no matter what address I entered
When it works it’s helpful
But I think the App has stopped working. I no longer get alerts & the App support website is Not loading. People have stopped leaving reviews too 🫠
Consistently reliable
This is my go-to air quality app, even on days I’m not in London. I have several air quality measurement devices (Plume Labs’ Flow, LifeBasis DM106A, HoldPeak HP-5800D) and I often see if these correlate with various online services (CityAir app, Defra UK Air website, AQICN.org, Plume app and general weather forecasts).
Over the years I’ve found the most reliable general indicator of poor air quality is the CityAir app combined with general weather forecasts. If CityAir is red and there are slow easterly winds then best avoid cycling in London! (For more localised information I’d recommend the Plume Labs’ Flow device though it can be a bit hit and miss).
I particularly like the concise, scientific explanations which help explain unusual observations, e.g. why good air quality despite an easterly wind? CityAir explains the current air mass travelled at higher altitudes over mainland Europe so didn’t pick up as much pollution as it would lower down.
Really great service, thanks very much from a mild asthma sufferer in London. I wish mainstream weather forecasts would use your excellent daily summaries.

Great idea BUT....
It doesn't work! It does not allow me to access a user group or plan a route which makes it useless.
Not reliable for high pollution conditions
Have noticed running to and from work some days that I can tell it’s a high pollution day (can taste the fumes even away from the road, cigarette smoke collecting in patches of air even when there’s no smoker there, I’m finding it harder to breath for the same pace and have sore eyes when I get home. Checked my other pollution app Plume and it says there are high pollution levels whereas City Air says its low!
