Mobile App for Patient Transportation

I am looking to develop a mobile app that supports the transportation of patients in times of medical emergency. This app will be used by both medical professionals and the general public, and primarily focus on the booking of ambulances for patient transportation. It will enable patients, hospitals, and medical professionals to book an ambulance in times of emergency with accurate, efficient, and reliable services at their fingertips. The app will also be capable of tracking the progress of the ambulance so that everyone can know when to expect it. It should provide a secure payment system that will add value to the whole process as well.
