I have looked a bit at the documentation (not the code yet) and I have to say that I am pleasantly surprised. They seem to be doing this right, including an attention to the reproducibility of the builds, which IMO is of utter importance in such a sensitive app: https://github.com/immuni-app/immuni-documentation/blob/master/Technology%20Description.md#reproducible-builds https://github.com/immuni-app/immuni-documentation/blob/mast... (long story short: Android builds are substantially reproducible, iOS are not because there doesn't seem to be a way to achieve that. They are doing the best they can.)
