In using DrChrono, a  cloud-based app, which means data storage without direct active management for doctors and patients,  doctors can get a big discount when calling the patient as its rate per second is much lower than other similar applications.
Doctors can customize the interface, schedule appointments, take notes and photos, write prescriptions and send them to pharmacies, look at lab results and update a patient's records. Patients can use a version of the app to keep track of their own results and appointments. Its Revenue Cycle Management service helps physicians and medical practices manage billing, collections, accounts receivable, insurance processing and other paperwork.
