The question

Start with what your own data can show.

Research has now found plastic particles in human samples such as blood and tissue, which makes this topic feel personal.

daygauge cannot measure or estimate your exposure, or any harm, from your phone or wearable data. It can help you keep track of a habit you want to change.

Quick answer

daygauge does not measure microplastics. You can log a related habit in Quick Log and see it next to your sleep, movement and heart readings.

  • Are microplastics found in the human body?

In daygauge

How the app handles this.

Signal
There is no microplastics score. daygauge does not import test results.
Confidence
Missing readings lower confidence instead of creating false certainty.When a reading is not available, daygauge says so rather than filling the gap.
Weekly Review
Weekly Review shows what changed, what held and what to try next.Your first Weekly Review is free. Later reviews are part of Pro.
Illustrative example

What this can look like in the app.

Custom habit: filtered water logged on 5 days.

Example
Confidence

A pattern is only called proven after it repeats on your own paired days. Missing readings lower confidence.

Next move

Try one small change, log it in Quick Log, then compare your next readings.

Example 1

Limit: daygauge cannot infer microplastic levels in blood or tissue from your habits.

Example 2

No test results: daygauge does not import or interpret microplastics test results.

Research

Further reading.

These studies describe groups of people. They help explain the topic, but they cannot tell you what will happen to you.

Research context only. daygauge does not diagnose, treat, prevent or predict disease risk. Personal medical concerns belong with a qualified clinician.

Limits

What daygauge does not do.

  • It does not diagnose, treat or prevent disease, or predict your risk of it.
  • It does not claim one habit caused a result. It shows the pattern, how confident it is and what else changed.
