In a health product, an empty state is safer than invented certainty

Empty screens are often treated as a design failure, leading teams to fill them with sample values, generic scores or AI explanations. In health, this can create a measurement and certainty that do not exist. Mizan Phase 1 therefore follows a simple rule: no reliable data, no generated result.

A useful empty state explains what is missing, how to add it safely, which permission is required and what cannot work without it. It discloses a disconnected HealthKit or Health Connect source and marks manual entries. Rule-based guidance runs only when required fields exist and does not use diagnosis or treatment language without context.

This may look less impressive at first, but it is the foundation of trust. A good health interface is not one that always has an answer; it is one that clearly shows what it knows, what it does not know and why it asks for data.
