## What is Health Library?

Health Library is an offline educational guide for people who want to compare supplements, lab tests, nutrition and wellness practices with clear context, limits and risks.

It is built for calm, practical reading: each card explains what the topic is, when it may be worth considering, where evidence is limited, and what to treat carefully. The app does not turn health into a habit tracker or a promise of quick results.

CARD DATABASE
• Browse supplements, biomarkers, devices, nutrition patterns, sleep practices and skin or hair topics
• Read a short conclusion, practical status, limitations, risks and useful context
• Search by name or card content
• Save important cards to Favorites

GOALS AND SCENARIOS
• Sleep and recovery
• Energy and fatigue
• Stress
• Weight and metabolism
• Immunity
• Memory and productivity
• Sport
• Skin and hair
• Heart health, hormones, microbiome and related areas

CLEAR PRACTICAL STATUS
Health Library separates topics by practical value: options that may make sense in the right context, methods that need caution, and approaches with no proven positive effect or important limitations.

DESIGNED TO STAY QUIET
• Works offline on your device
• No account
• No overloaded habit system
• No pressure, streaks or unrealistic claims
• Fast filters, search and Favorites

IMPORTANT
Health Library provides educational information based on research. It is not medical advice, a diagnosis, or a substitute for a clinician. Consult a qualified specialist before medical decisions, supplement use, lab testing, or treatment changes.
