The latest version of Contrac now analyses the keys downloaded from the server against thoe collected using Bluetooth and provides an up-to-date risk assessment for the user. This is a pretty big step, because it means the app now has all the pieces needed to perform the full exposure notification cycle (diagnosis upload, key download, exposure analysis). There are still plenty of potential improvements of course, the main one being that it needs to be plugged in to the official severs rather than my test server, but hopefully that'll come soon. In the meantime, get it from OpenRepos and github.
