great app

very convenient app for knowing the exposures you have been around but i wish they would not have gotten rid of the exposure details. They should re-add the window where you can see the exposure lengthens as well as the risk level .

Needs Improvement

I love the concept of this app, but I don’t think it was ready for release. To begin with, it is very unclear what the risk level ranking is out of (10?), as well as what that actually means. Each time I have been exposed it’s been ranked as a “6” with no further information. That seems like a high risk level, and yet no suggestions for next steps were made available as promised. Is 6 actually quite low? Friends who have had the same exposure times have much lower risk levels. Why is mine so high?
Additionally, the notifications are very confusing. I got a notification on Sunday (8/31) that I had had no exposures during the week. Then on Monday night (9/1) I got an alert that I had been exposed... on 8/27 and 8/28. Today I got another notification for an exposure on 8/28. I am wary of these alerts because they all look exactly the same (risk level and time exposed). Are they accurate? Is it a bug? The time exposed seems inaccurate as well. For all three of my “exposures” the times are listed as: “0min, 0min, 3min, 0min” in that exact order. My friends have the same for different supposed exposures on different dates. This app needs more information and more clarity.

Please bring back the exposure details - Update: I’m not sure it really works.

Update: My roommate has tested positive for COVID-19 since my original review. We both have the app downloaded, and being able to look at the possible exposure details was what prompted her to get tested. She reported to the app that she tested positive 3 days ago, but I have yet to receive a possible, much less significant exposure notification. 3 days before her positive result, her and I were sitting probably 4 feet apart watching a movie and both had our phones with us. Just with that much, I should have received a significant exposure notification. I really am questioning if this app works. I’ll leave it on my phone as it doesn’t take up much space, but I won’t be relying it on it’s accuracy.

Original Review: With this most recent update, they have removed the exposure details for possible exposures, and it’s very frustrating. Please bring this back.
