Drinks:Ration is under active development, with the trial due to commence in May 2020.
I am happy to report that the first paper from InDEx project, funded by the Medical Research Council, has been accepted and published in Journal of Open Research Software. You can read more about the InDEx project via its tag. The paper explains the development and deployment of InDEx, and unlike many other research projects, we have also released the source code.
The software is available from GitHub.
The paper is available here.
