### 1/5 — US Embassy in South Africa doesn’t have the app yet

*2021-01-22*

Is there a way to request that the local embassy install this app, or it is just a matter of time?

### 2/5 — But why?

*2020-12-24*

Each time I open the app, it’s as if I am opening it for the first time. It doesn’t ever remember that I already created an account. It prompts me to sign in, create an account, set preferences, etc. I appreciate the helpful information, but I have to click through 4 different screens asking to either “skip” or “don’t show again” before I get to the information I’m hoping for.

### 3/5 — Needs improvements

*2020-11-14*

Definitely needs more work.  In my city AQI is 147, unhealthy for sensitive groups, and the App says: good time to go outside? Also, what’s with “reload” button, that appears after starting the App?

### 5/5 — Great app!

*2020-10-22*

This app is very useful in determining the air quality of your location, a location you are traveling to, or just any location you are interested in. The app is very easy to use and breaks down the air quality in a way that is very easy to understand!
