I have been participating in the Covid-19 research, enabled by this app, since March. The app works well, but it appears to track my location for a long and indefinite time after leaving the app, even though I have l location sharing set to “only while using.” Somehow they seem to be evading the “while using” to continue tracking location unless I force-quit the app. While I understand that there may be some value to Covid researchers in tracking who is going out and who isn’t, this seems like a clear violation of trust. Once you leave the app, tracking should cease just as it does with every other app when “only while using” is selected.

Overall, the app works very well. Sign-in was quick and easy. The questionnaires work fine. Although, I haven’t figured out why the study hasn’t asked if I’ve been vaccinated yet (I have). When I first downloaded the app, I noticed some negative reviews about location tracking. Although I used the app for many months without an issue. Then recently the app starting following my location even after I closed the app (Apple places a blue indicator at the top of the Home Screen), even though my setting was set to allow only when using the app. After two days of that, I had to go into the settings app and turn off location services for that app, which seemed to solve the problem. It’s a strange bug, though.

Signed up. Then, they didn’t send a link for the app, so an email was sent requesting help. After a link was sent, downloaded the app - I should have read the reviews first. After reading the reviews, I deleted the app.Be The Match was the group that sent the invitation. But one of there employees had posted some very negative/unprofessional comments on one of my websites - they didn’t know that their IP address was recorded with their comment. So I had to deal with that.In addition, I had a very negative experience when BTM called/emailed me about being a potential match. So those two incidents just didn’t help.Not sure why BTM contacted me about this project but after seeing the reviews, I just don’t have a good feeling.I need a app that was made by a pro, not by a student working on their degree.There are far too many negative reviews for the app. It uses too much battery power.I would love to help and have even volunteered for the stage 3 vaccine trials. I even tried to volunteer for the BTM program.It just seems like these groups and their programs/research are poorly run. (My spouse is a scientist and I have been in several different labs that are professionally run.)I can not run the risk of having a problem app, that also doesn’t respect privacy, on my phone!I have deleted the app and am withdrawing from this poorly run program!

I just saw this app on SciShow. I downloaded it and it works. I wanted to leave a review because so many others were reporting problems, and when I saw those problems I was skeptical about it. But having now used it for several days, I legitimately don’t understand where all these negative reviews are coming from about bugs and login issues because I haven’t had any problems at all. I’m running on an iPhone X right now which has been updated regularly and everything works fine. It’s literally never crashed once. Anyway, I hope their research helps end this pandemic and I’m happy to be a part of it. It feels good to give back somehow.
