The BARMER-App is a free iPhone application designed for users to manage their health insurance and related services digitally. This lifestyle app streamlines various health-related tasks, allowing users to submit applications, access important documents, and communicate securely with their health insurance provider. Key features include a quick access hub for essential services, a bonus points system for rewards, and the ability to track medical expenses and benefits like maternity pay and rehabilitation services.

Additionally, the app offers a reminder service for health check-ups and vaccinations, a digital dental bonus booklet, and an overview of personal costs. Users can also download a replacement certificate if their health insurance card is lost. To ensure data security, the app requires a BARMER user account for login, with extra protection through a registered device. The app is available for iOS 18 or higher and is designed for BARMER members only.
