add contact tracing for STDs
Something similar to the new york contact tracing app. If two users who have chatted and are in the same location for more than 15 minutes (or some time frame), grindr saves the data. Users can then report STIs anonymously in the app and have them sent to all possible hookups. there can maybe be a risk of exposure metric: if there were 30 grindr users in one place its most likely a bar and not a hookup. If users were in the same building but haven't chatted then they probably didn't meet up, etc.
So if users are on a date but don’t have sex, then a person gets a notification that they may have been exposed to an STD?
