Byldr is a no-code platform for building mobile health applications. It targets digital health researchers, university courses, hospitals testing clinical prototypes, and startups that want a working app in front of real users. Participants use a mobile app with built-in tools such as chatbots and language models, surveys, journaling, gamification and wearable connections. Researchers design and manage projects in a web portal without writing code. The team also offers support with study design and custom development.
Byldr GmbH is a Swiss company based in Schlieren, and its site names no foreign parent. The vendor states that the platform is hosted in Switzerland, complies with the GDPR and the Swiss revDSG, and works with an external data protection officer. It publishes data protection terms, a transparency document and a sub-processor list. Switzerland is not in the EU but is an EFTA country with an EU adequacy decision. Because health data is highly sensitive, ask which sub-processors handle the language-model features and where they operate.
