Great idea. This need will serve not only Ghana but many developing countries in Africa.
i will be glad to see how this unfolds. my only question is how this will be monetized.

Great idea.
How will the pill dropers be paid? cash?
who will own the cars? and will remote areas have the necessary technical capabilities to make tracking easy?
Have we thought of patient confidentiality issues?

First and foremost, congrats on your big idea.
My first question has to do with how you standardize the errors. Many jurisdictions have different prescription guidelines and protocols coupled with differences in dosages. How do you seek to address this?
Secondly, if a patient sends a picture of a fictitious prescription, how do you track and prevent drugs getting into the wrong hands.
thirdly how do you seek to monetize this idea? sell the app?
