Continued use of GPS running in the background can dramatically decrease battery life.
Smoggy updates your active location's air quality as infrequently as possible to be as kind to your power as possible. Smoggy can also track manually searched locations if your GPS is switched off!

Way off on readings

Today app says Fresno at 15. Same app lists worst air in the country and fresno is on the list at 115. Can't trust this app. I may have paid for this app years ago but today I will delete. Real time air quality reports I now get through a website and those are accurate.

Crashes immediately

Downloaded it. Tried to find my city while being elsewhere. Text is dark grey on black so almost unreadable. Upon selecting the city the app crashed. Useless junk. Want my 99c back.

Use it constantly

I fantasize of moving somewhere away from LA's smog to a city with clean air, but it's not easy to find which one...

Smoggy helps me track my wish list.

(I moved to Portland!)
Love the latest update!
