What surprised me most is that the UI does not seem to be mobile responsive, and does not work well on smartphones. I would have guessed that in developing countries mobile use would be hugely important?
The UI is still a massive WIP, but I am working on making it fully responsive down to tablet size. Our goal is to accommodate viewports down to tablet because in hospitals where the software will be run (and is already running in a few CURE hospitals) medical and administrative staff will be using it from laptops and tablets.
Viewports lower than 600px are not currently a consideration, however, as we don't currently have a legitimate use case for the software on phones.
A laptop would also give you more time, but not as much as a smartphone.
