The service behind the application

A clinic relationship that continues between visits

A patient may need to arrange a consultation, find a previous result or help a family member manage their records. Each task depends on the right appointment and patient information being available to the person using the app.

The DYM Medical application brings those tasks together. Patients can register an account, link their patient ID, book a visit and return to medical records afterwards. Connected family profiles extend that access beyond the individual account holder.

01 · Account access

An app account linked to the patient’s record

Creating an app account and linking a patient record are separate steps. The user guide shows phone verification during registration, followed by a patient ID and one-time password (OTP) process to link the medical profile.

Account registration

The registration journey collects contact and account information. The next step in the guide verifies the phone number with an OTP.

Login and the patient home screen

After login, the home screen brings appointments and the main patient functions together.

Connecting the medical profile

From the account screen, the patient selects the unlinked profile, enters their patient ID and completes phone verification. The app confirms when the link succeeds.

This establishes the connection used to access medical records through the account.

02 · Before and at the clinic

Booking, pre-visit information and QR check-in

The appointment journey covers choosing a clinic and time, submitting the booking and completing a pre-visit survey. At the clinic, the patient can display a QR code for check-in.

Health check-up appointments

A separate health check-up booking flow lets patients choose the location and date, select a time slot and confirm the appointment. They can return to choose another slot before submitting.

Appointment changes and history

The guide also covers cancelling an appointment with confirmation. Booking history gives patients a way to return to earlier appointment activity.

03 · After the visit

Medical records and results on the patient’s phone

Patients can open a medical record, read the result details and view associated result images where available. Height and weight charts provide a separate view of recorded measurements over time.

Adding a family connection

Access and sharing controls

A connected profile opens the family member’s information, with routes to medical records and height and weight charts.

Patients can disconnect a profile through a confirmation step. A separate shared-profiles list lets them review and cancel profiles they have shared.
