Looks promising, but not helpful if you live in other towns and cities as it covers London only.

Route mapping and guidance works smoothly. Useful tool.

Appears to be abandoned with no working function except a few links.

Looks good, as an Edinburgh resident I'd like to see it showing data across the UK, not just London

Nice idea, but doesn't work. All attempts to open it produce the message "Unfortunately, City Air has stopped." Unfortunate indeed!

Does not open after latest update

Blank user group choice screen, blank home screen, no pollution data on the map whatsoever. As bad as London Air. Seriously, does KCL even test their apps?

App keeps stopping

As if the work of an individual, forecasts are slower to appear during the weekend, and the app now crashes immediately after opening. But when it works, it educates on the factors which increase pollution - winds from Europe, length of daylight, etc. It is of little comfort, though, to read that pollution is low when a brown smog can clearly be seen over the City from Parliament Hill.

Disappointed with this product as it only show London. However not everyone resides in london. Drains the battery.

Shows why London is the asthma capital of Europe. It doesn't give me notifications like it does in the video.

'Unfortunately City Air Has Stopped' URGGGGGGGH. Good when it's working.

Crashes regularly and randomly. Cannot see tube lines nor set markers like in Gmaps.
