Interesting although it seem as though Singapore's "TraceTogether" app was able to work successfully without any of these APIs no?
Tangentially related - Singapore plans to open source their app. There's a few details about how it works here:

Also interesting to read some of the reviews of the app here:

- rct42 7y agoThey've released their open-source version of the app, OpenTrace https://github.com/opentrace-community/ https://github.com/opentrace-community/ Interesting in the Android version they request ACCESS_FINE_LOCATION (i.e., access to GPS) instead of ACCESS_COURSE_LOCATION (i.e., access to BLE). They have also include Firebase analytics (which captures city-level location data) into the app as well.
- bogomipz 7y agoWouldn't bluetooth be preferable to GPS since GPS requires a direct line of sight? And Singapore being an urban area with underground mass transit and lots of shopping malls I would have though that bluetooth would provide better accuracy of contact/proximity.
