What about contact tracing apps? Tracing won't work unless you know who was nearby each infected person. It's difficult to find that info unless a big portion of people are using a tracker app. Is that sort of thing happening where you are?

It's been announced here (Ireland), though the official government contact-tracing app is as yet unreleased. It's believed to be a based on Singapore's BTLE one.

It's largely irrelevant though. As much as it may help a little, this just isn't manageable through contact tracing. While Singapore are being lauded for their CT approach, they've still largely been successful in their efforts due to social distancing (and a culture of widespread adherance), along with things like widespread testing, and effective govt. communication of data.

It's happening here in Israel. The government is promoting an app which claims it stores the location history on-device and fetches known-disease-vector data from the server to compare it locally. (For good or bad it doesn't use the device's existing location history if it's already stored...)

They just announced it's had 1M installs (in a country of 8.7M) in the last week.
