My Specialist Appinion (MSA) is a UK-based digital healthcare service that connects patients with GMC-registered Consultant Specialists through a secure mobile app. Its aim is to make expert medical guidance more accessible, convenient, and affordable, helping patients seek advice without waiting for an NHS specialist appointment or incurring the high cost of private care.

Patients can register, choose a medical specialty, submit a question, and receive personalised guidance through the app’s messaging platform. The service offers access to specialists across fields including cardiology, ear, nose and throat (ENT), and dermatology, with opinions starting at £75. Patients can also request a second opinion about unresolved concerns following a clinic visit. To support consultations, the app lets users securely share documents, imaging reports, laboratory results, and photos.

MSA describes its service as available around the clock and emphasises timely responses, confidentiality, and data protection. Its platform uses encrypted security software and is stated to be GDPR-compliant.
