Was this some sort of student project which has now been abandoned? ### 1/5 — Hopeless. *2023-07-31, version 5.0.1* Asks me to log on - how, exactly? Useless ### 1/5 — Does not do anything *2023-07-29, version 5.0.1* On opening the app it presents me with a login to access resources. Obviously I can’t do this as I don’t have a login. I skip past that and try to add a location and nothing happens. Useless ### 1/5 — Broken app *2023-07-08, version 5.0.1* Doesn’t work, No map, no data ### 3/5 — Stale data - was tap to retry? *2020-08-29, version 5.0.1* Tap what or where? The data I have says it is "stale" and that I should "tap to retry" but there is no indication as to where or what to tap. Force closing the app does not update the data. It seems that it could be useful if it delivered up-to-date data but alas it dies nothing of the kind. Stuck with 4 day old particulate data it's not much use. Nice try. ### 5/5 — Great app. Can we get a Garmin version? *2020-01-18, version 5.0.1* Would be great to have real-time map guidance on the Garmin devices. But just a widget or data field for those devices that don’t have mapping would be great as well. Thank you Ed ### 2/5 — Notifications?? *2019-04-06, version 5.0.1* I’ve set up notifications for my favourites....but never get any on air quality changes? ### 5/5 — Great information *2019-03-12, version 5.0.1* I just wished there were more logging points. But very useful 😀 ### 1/5 — Disappointing *2018-06-19, version 5.0.1* Not much info and no key to understand what the readings mean. Now deleted. ### 1/5 — Pathetic *2017-03-13, version 4.0.3* Rubbish don't bother ## Frequently asked questions about London Air ### What does the London Air app do?
