### 1/5 — I CANT BREATHE ANYMORE!!!

*2026-08-13*

This app really helps me to keep my windows shut and the AC on. We hate fresh air now and don’t go out unless this app lets us. We even have N-91 masks, but don’t dare go outside without goggles and masks on!?

### 3/5 — Air

*2026-02-02*

Good information

### 1/5 — Brutal ads take over entire operation of phone

*2025-09-04*

Could be such a good app but gaming ads take over operation of phone once installed

### 5/5 — Air Quality App

*2025-08-03*

Rocks

### 1/5 — Just Ads

*2025-02-13*

Terrible app, half of the screen is covered by ads and you can’t even see the relevant information you actually need ! Too much is too much at times

### 5/5 — Your app is malfunctioning

*2025-01-15*

Your app is malfunctioning

### 1/5 — Irritating design

*2024-11-18*

Information seems fine if limited - but if you haven’t paid for an ad free version then an ugly ad takes up most of your phone. I installed and then uninstalled

### 2/5 — Ads

*2024-07-21*

I can appreciate that an app must generate some revenue to fund itself and those that built it, but the half-page Google ads covering much of the info that we use the app for is ridiculous.

### 1/5 — 3-30-24

*2024-03-30*

No stations in my area Southwest Florida
Fort Myers, Naples

### 1/5 — Outside Thick With Smoke

*2023-11-07*

This morning the air outside is thick with smoke yet the App is saying air quality is good! So therefore the App is useless in warning me of amy problem with pollution.
