User reviews

Excellent App

This is a well-designed, intuitive app.

Useful

Mostly intuitive and easy to use.. a few little idiosyncrasies but nothing to worry about. Much better since the ability to edit your profile, cos that can change in a medical sense.

Keeping track

I love that I have been able to keep track of all my testing and vaccines in one place.

A good App!

We have been using this app since it was first released, and find it to be easy to use. We hope that the data is valuable to researchers and policy makers.

Crashes

I can't get past the screen where I add my email. I've deleted the app, restarted my phone, and downloaded it again. Crashes at the same point. When I open it again, it fills the screen with, 'Take 1 minute each day ...' every time. With no option to join, next or any other way to get rid of this screen other than closing the app. I'd like to participate.
