Cwa-wishlist: Display total infections & shared diagnostic keys on first page

Created on 20 Oct 2020 · 4Comments · Source: corona-warn-app/cwa-wishlist

Feature description

On the initial screen of the app, show publically available information:

Total infections (in Germany) in last 24 hours (source: RKI)
maybe: Total infections in state last 24 hours (current "Bundesland" based on GPS)
Total shared diagnostic keys in last 24 hours (source: https://micb25.github.io/dka/) & that it's anonymous / not known who the people are
Show percentage of shared keys vs total infections (also as text, e.g. "10.4% (10 out of 100)", as actually not everyone can interpret percentages correctly)

Active users of the app:

have no feedback about the effect of using it ("is it worth using?!")
are required to use 3rd party websites to get information about the daily statistics (usually only the news papers which only publish statistics by the RKI, the micb25 statistics are basically unknown)
cannot help in motivating others to use the app ("why should I, I don't see any and have not read about any impact, not even from the RKI?")
can help responding to "I just see the numbers are increasing even though 19 million are using it, so it's a waste!"

Especially the total shared diagnostic keys is imo important and critical:

Users see an effect (shared keys) even if they never see any notification --> answers the question "is the app actually working and does it have an impact?"
Users can show the effect of the app (shared keys) with others --> answers the question "is it worth it?" --> can increase acceptance and usage by others
Psychologically, app users seeing other positive tested people are uploading their diagnosis may increase the likelihood that they will do the same ("be part of it") --> increased amount of notifications of users --> may increase testing/being more careful --> may lower infection increase
