Design intent
Role-specific clarity
The application provides distinct experiences for patients and doctors, ensuring each user only interacts with workflows relevant to their role.
Real-time reliability
Scheduling accuracy was prioritized by ensuring availability updates propagate instantly across the system without manual refreshes.
Trust by default
Mandatory doctor profile completion establishes credibility and ensures patients interact with complete, reliable provider data.
Low-friction interaction
The booking flow was intentionally kept short and predictable, allowing patients to confirm appointments in under a minute.
