Good UX, crowd-sourced data. One problem is that current (momentary) measurements are shown as percentages of EU/Polish, but that doesn't make sense, because a norm signifies not a momentary exposure, but an averaged daily one. It'd be better to give objective values in micrograms and only additionally current daily average with a prognosed percentage.

Thx, for your remark. I would agree apart from that all other apps (even official one), websites or "smog alerts" pages, are using norms in same fashion which became a standard. Yes, it could be better but being only app that does it isn't good as well.

The best app I know in terms of quality of information. It uses multiple sources and thousands stations. Display info in Polish, EU and WHO metrics. And of course it gives you polution notification.

This app is a nice change from all the clunky and bulk apps that became notorious in the store and that forgot about delivering true value. Canary is simple, fast and useful - example of what apps should be. Great job Michał!
