Jeremy Clarke (ID: 00000099a778a343) Voted 3 ★ - Updated 03/22/2017 I added this to chrome after installing the app on my android mobile. Both suffer from covering some London boroughs well, some less well and some not at all. More uniform coverage would improve this no end. Mind you, basic functionality works much, much better in this extension than in the android app which is in need of some serious testing on different phones and overhauling.

Dan Jeffrey (ID: 0000001716af2f7e) Voted 4 ★ - Updated 12/30/2015 Good but missing Hounslow / Brentford & Isleworth boroughs. Considering there's a substantial monitoring station smack bang in the middle of Chiswick I would have expected them to be included.
