### 5/5 — Helpful for UNO

*2021-08-27*

Makes me feel good knowing that I’m working out next to healthy people in H&K

### 1/5 — Trash

*2021-05-07*

This app is trash.

### 3/5 — Overheating

*2020-10-26*

I noticed that my phone started overheating, the battery took a long time to charge and then would quickly deplete. That all happened after i downloaded it, so i deleted it and it stopped happening. It’s a nice app but I think there might still be some bugs :)

### 2/5 — Unclear purpose, poor construct

*2020-09-09*

Maybe this is for someone’s research project? Seems like a cumbersome and ineffective screening tool. No feedback on what to do or who to call if you have symptoms. No rolling dashboard of data from which to draw.  Do you honestly think asymptomatic ppl will sign in and answer questions daily? Huge bias in the data....
Mediocre at best.
