@Jonathan_Fernandes, As @Max has shared, we have surveillance CHT applications (notably the reference application linked above, but also those tailored to the Kenya context). As you suggest, these ready-made CHT Applications may be suitable to your context with minor tweaks.
cc: @philip from our Kenya team. We may need a few days to discuss privacy concerns with stakeholders in Kenya before sharing other application specifics.
Choosing to re-use one of these existing CHT Applications will lessen the burden of setting up your system in Zimbabwe, but you’re still going to have to go through numerous technical steps to get this ready to use. You can’t simply create users for Zimbabwe on our Kenya system, you’ll need to set up a new Zimbabwe instance of this CHT Application. For example, someone needs to do the basics that are required for hosting any web service - getting a server to run it on, getting a domain, SSL certificates, etc. Shreya probably mentioned capacity building services which we offer to help your technical teammates with these steps.
So even with the right CHT Application as your starting point, this is going to require some people with some technical skills and time. If tweaking the application for the Zimbabwe context is required, additional technical skills and time are necessary.
