Free tool · Patient heatmap
Where do your patients actually come from?
Drop in a patient list and see where your patients live, ZIP by ZIP. Add household income and your practice, and find the areas that produce patients — not just the ones nearby.
How it works
A minute,
and nothing to sign up for
- 01
Drop your list
Any export with a ZIP code column, CSV or Excel. It is opened in your browser and only the ZIP codes are kept.
- 02
See where they live
Every ZIP area shaded by how many of your patients live there — or by how many per thousand residents.
- 03
Target what works
Add household income and your practice, see how far patients really travel, and save the map to share.
What leaves your computer
- Your file
- Never. It is read here, in your browser. Only the ZIP column is kept, and everything else is dropped the moment it is read.
- The ZIP codes
- The list of codes — not who lives in them, not how many — goes to the U.S. Census Bureau for their shapes, population and, if you ask for it, household income. The top few go to zippopotam.us for their town names.
- Your practice
- Only if you add it. A Google Maps link is read right here; a typed address is looked up on OpenStreetMap.
- The map
- Stays with you. We never receive it — save it as an image to keep it.

We do not work with everyone, and you should not either. The first call is where we both find out.
