— Overview
Umm is a HIPAA-compliant chronic disease management app. Patients monitor vitals (BP, glucose, SpO2, temperature) via Bluetooth medical devices, complete daily CarePoints tasks, attend virtual appointments, and receive prescriptions from doctors. Doctors remotely track patient health and adjust treatment plans in real time.
