At Custom Medical, we combine Usability Engineering, UX Design, Software Development, and Compliance Documentation to create safe, intuitive, and inspiring medical and health products. As an ISO 13485 and ISO 27001 certified company, we guide you through the entire development lifecycle - from early usability testing, through final approval, to active post-market surveillance (PMS).

• We test with users internationally. Our cutting-edge test labs allow realistic simulations of low and high-risk medical/health environments - from home use over ORs to intensive care settings. Whether on-site or streamed, we ensure real-world feedback by conducting usability and UX tests with patients, healthcare professionals, and everyday users. Our goal: to refine your product before launch, ensuring it is intuitive, safe, and optimized for real-life use.
