Every room on one chart
A line per detector, so you can see which part of the house needs attention.
Know your air.
Radon is invisible, has no smell and is the second leading cause of lung cancer. Radon Tracker turns your detector's readings into a clear answer: are we fine, or do we need to act?
Live readings
Are we fine, or do we act?
Each detector shows its latest reading big, colored and named by EPA level. Tap one for its history, drag across the chart to read any moment, and watch new readings land on their own.

What's inside
Everything your detector wished it could say.

The pattern behind the number
Your long-term average, plus when in the day and week radon tends to peak.
What the levels mean
EPA, WHO and Health Canada levels explained in plain words, right in the app.
A nudge when it matters
When radon reaches your level, when a detector goes quiet, and when it's back to normal.
One glance, home screen
The latest reading and its level without opening the app.
What to do about high radon
Clear next steps when readings stay high, from retesting to mitigation.
Notes
Did the fan work? Proof, pinned.
