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.

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!

Very clean and readable UI. It lets me create a list of pollution stations that I care about and it displays all the measurements on the main screen. I can also track historical data for a given station for past a week. Nice :)
