Having the app installed (i.e. not deleting it!)
Keeping location tracking on
Recommending the app to others.
What incetivizes people?
Reards, badges, things they can share on social media
Skill-based games, especially where you can unlock new (harder) challenges as your skill increases.
Leaderboards - ideally finely slices by location & time so many people can be “top” in some sense.
Ability to form teams & groups - and compete with other groups on these leaderboards.
Some ideas:
Personalized download links for the app, where we can track who made the recommendation
“Streaks” could work well for symptom-reporting. Need to design mechanics based on how frequently we want people to report their symptoms.
Notifications could come from app, but might be better to link in diary apps that can drive the reminder notifications themselves.
Location sharing for uninfected people could be useful too: a way to build maps of where people are going in general.
A key challenge in the UK is to know where to go that won’t be overcrowded…
Suggested prediction game around where the busiest places well be.
App could have two modes: “Privacy mode” & “Social mode” - where social mode is willing to share a lot more data, and allow the user to participate in Social games related to the app.
