Begin with the Person
When health changes are unexplained, important details can become scattered across appointments, memories, notes and test results. Parallax 1 helps you bring those details together in a clear, structured record. The app records reported symptoms, when they began, how they have changed, relevant vulnerability factors, time spent in different environments and any patterns noticed when away from or returning to a building. It helps identify questions that may deserve further discussion and produces an organised summary that can be shared with an appropriately qualified healthcare professional.
Principal Benefits

- Records vulnerability and changes over time

- Prepares more useful information for healthcare discussions
- Identifies where property information may also be needed
The problem it helps organise
When health changes are unexplained, important details can become scattered across appointments, memories, notes and test results. Without a structured record, a healthcare professional is left with fragments rather than a clear chronology.
What it helps you do
Parallax 1 helps you bring reported symptoms, vulnerability, chronology and possible environmental exposure indicators together in a clear, structured record that can be shared with an appropriately qualified healthcare professional.
How it works
You record reported symptoms, when they began, how they have changed, vulnerability factors, time spent in different environments and any patterns noticed when away from or returning to a building. The app organises them into a structured chronology and summary, and identifies questions that may deserve further discussion.
What you receive
An organised symptom and exposure chronology with a structured summary suitable for sharing with an appropriately qualified healthcare professional.
Who it is for
Individuals and families who suspect indoor environmental factors may relate to their health concerns and want to prepare a clear, factual record for their healthcare professional.
