One of my sisters and her husband live in Zambia, where they do public health work. Specifically, he works on malaria[1], and one of the greatest challenges he faces is field data collection. Enabling everyone with a compatible phone to send in data would, I'm sure, be incredibly valuable.

I'm bummed that there aren't any public health tools included in this app. Hopefully they'll consider adding something like that in the future.
