What is the NHS App and what can it do?

The NHS App is the primary digital interface between citizens and NHS services in England, with over 35 million registered accounts by 2025. Core functionality includes GP appointment booking, repeat prescription ordering, viewing the GP health record (test results, medications, documents), vaccination status, organ donation preferences, NHS 111 online symptom assessment, and hospital appointment management. It connects to GP systems via GP Connect FHIR APIs with NHS Login for identity verification.
