DEN™ — Differential Exposure Navigator

DEN™ — Differential Exposure Navigator is a personal exposure and symptom assessment app designed to help users recognise patterns that may be linked to environmental conditions.

The app guides users through a structured 12-screen process in under 15 minutes, helping them assess symptoms, exposure factors, vulnerability indicators, and possible environmental influences.

Rather than guessing whether a building, room, exposure, or situation may be contributing to symptoms, DEN™ helps users organise the information clearly and consistently.

It is designed to support better decision-making around:

• Symptom and exposure tracking
• Possible environmental triggers
• Vulnerability factors such as pregnancy, asthma, compromised immunity, children under 5, elderly occupants, and clinical concern
• Whether further investigation may be beneficial
• Whether healthcare or professional advice should be considered

DEN™ does not diagnose illness or replace medical advice. It provides a structured way to assess patterns and identify whether additional investigation may be appropriate.
