Marvin Blome

Founder and Software Engineer · Hamburg, Germany

Marvin Blome is a software engineer based in Hamburg and the founder of InnerPulse. He writes data-driven articles about mental health on the InnerPulse blog, based on systematic analyses of public online communities, peer-reviewed studies, and authoritative sources such as the WHO, APA, NIH, DGPPN, and PubMed.

Why InnerPulse?

InnerPulse grew out of a simple idea: make mood tracking private again. No cloud, no account, no ads. The app runs fully offline on iPhone, is GDPR compliant, and was built in Hamburg. One-time purchase, no subscriptions.

How the blog is written

Every article combines three sources: verified scientific studies, quantitative analyses of thousands of posts from mental-health communities, and clear, actionable conclusions. No self-help clichés, no unverified claims of cure.

Important note

Marvin is not a therapist, psychologist, or doctor. The articles on this blog are journalism, not medical advice. For psychological concerns, please consult a professional or contact a local crisis line. In Germany: Telefonseelsorge, 0800 111 0 111 or 0800 111 0 222 (free, 24/7).
