A long time ago I read an article about this gadget that is supposed to detect pesticides and I thought it sure would be cool to have one.   However, we don’t have an iPhone.

From https://mylapka.com/pem:

The most beautiful science ever.

Lapka PEM is a tiny, beautifully designed personal environment monitor that connects to your phone to measure, collect and analyze the hidden qualities of your surroundings.
Lapka’s precise sensors respond to the invisible world of particles, ions, molecules and waves. But Lapka doesn’t just quantify what it measures. You get results that are specific to where you are. On the street, at the office, inside a child’s bedroom, or on an airplane: the Lapka app compares its readings to average guidelines for each individual environment.
You can collect snapshots of your comfort throughout the day to create a diary or share with the world around you. Keep the conversation going.


  1. Professionally precise. Lapka Radiation reveals highly accurate information about the radioactive particles around you and how they might be affecting you.
  2. Detects electromagnetic fields (EMF), which can be caused by electronic devices, wireless transmitters, or nearby power lines.
  3. Designed to detect significant quantities of nitrates in raw produce left behind by the use of synthetic fertilizers.
  4. The temperature and relative humidity of your environment are measured, combined, and compared with our knowledge base of comfort standards to help you better understand your personal climate at any moment.

Please let me know if you used this gadget!
The Lapka organic is $79 and if I had an iPhone, I’d try it myself.
