What applications are you building for COVID19?

Curious to know what projects other people are building for COVID19 that could be used by the general public. There have been a couple of interesting projects where software developers and other technical thinkers have released open source projects (like this one https://github.com/SolaceLabs/jhu-covid19-stream-processors and this one https://github.com/NovelCOVID/API). What have you, or your company, have built?
