intro video






Designed to detect significant quantities of nitrates in raw produce left behind by the use of synthetic fertilizers.
Lapka Organic basically detects whether or not raw fruits and vegetables were grown organically. The little probe simply measures ionic conductivity, which correlates to the quantity of nitrates left behind from nitrogen-based fertilizers.
Each fruit and vegetable has a defined limit for nitrate concentration, and conductivity that significantly exceeds these limits suggests the use of non-organic farming practices. Head’s up, Whole Foods!


Lapka Personal Environment Monitor (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.


The ability to see precise measurements and beautiful visualizations of what lies beyond our perception is inspiring and addictive – whether you’re simply curious about the unseen details of your environment, or actively searching for ways to improve your quality of life. Lapka lets you discover and play with the smallest details that shape your world.



  • Detects whether or not raw fruits and vegetables were grown organically.
