What users are saying

1. Is this physical contact or does my 1.5m distanced conversation with a cashier count?I would like to zoom in on the map.CORONA-VIRUS SYNDROME The Ultimate Genocidal Bioweapon System HOW YOU CAN BEST AVOID the VIRUS What “YOU” MUST know in order to survive as long as possible! The disease process caused by COVID-19 is best described by the following new disease name: COVID-5G- Chemtrail Syndrome #STOP THE CRIME .

2. A very very short intrusion of that 1,5m, does that count too? Or just if someone stands there for longer? Also suggestion: add a reminder function maybe, so the app will notify you to go and answer the questions daily.A fine app, but I can't let anyone know the (pretty important) information that I work in a supermarket, which makes it seem like I hug 20 random strangers everyday.

3. only problem is that I am not able to zoom in on the map of the NetherlandsCould you make the map in such a way that it can be zoomed in, else it is impossible to see in randstad what is going on.Map is useless without zoom functionalityPlease add a better description on "how many people have you had contact with?".

4. But great that we try to capture more data..Quick and concise but maybe too concise when it comes to the questions, for example the how many people came within 1,5m of you question.

5. It would be good to add an explaination, for instance to the question referring to how many people you've been in contact with.

6. I agree with the other comments on the description of the contact not being very clear.

7. Great initiative!!!! I would say link it to gps and capture more data.

8. (Oh btw, I also can't select more than 20 people)Good initiative, but questions are a bit unclear.

9. If you go for groceries is it everyone you crossed on the aisles?Good clear app, high detail map.

10. In addition I have a mixed household with kids staying a half week here.

11. I want to have that permanent at one of the parents houses during the pandemic but for now that is not the case.
