I think i can recommend one health app that one of it't feature is you can able to purchase medicine and other health product even across country, so for me i recommend AfriHealth and yes this health app is developed by africa country which surprisingly a well done health app despite of we know that they are not that equipped but with an innovation using the influence of bitcoin and because of that the transaction is a lot more easier over the phone, the afrihealth provide services such as online purchase of medicine, access to your health record, online setting an appointment to a doctor and also you can choose insurance plan incase, and when theres an emergency? You can also use afrihealth app to use for ambulance response near your neigbothood.
