About

UDH

Features
Read full description

Our app is purely a booking platform that allows patients to schedule appointments with doctors within the clinic for consultations or follow-ups. The app does not collect any health-related data, perform any medical measurements, or use the device's sensors for tasks such as taking X-rays, measuring blood pressure, body temperature, blood glucose levels, or blood oxygen levels. The only health-related feature in the app is an attachment section, where the clinic administrator—via the admin panel—can upload PDF documents such as test results or reports. These are shared with the user simply for their personal records. The app itself does not process, analyze, or interpret any of this content."
