@m453h files changed too many to review at 1 go. Couldn't we have started with 1 app (say roboshield in a separate PR) then open another PR for codeforafrica against the first PR?

I am also open to other suggestions.

I totally feel your pain 😢. I kept the two apps to demonstrate how the multi-app setup would work. I actually reduced the scope by excluding some CivicSignal collectoins/blocks because it was becoming too large, you can first confirm if the functionality works as intended locally before we decide to remove them (if necessary)
