When shopping at your local grocery store, do you look for the words “all natural,” “organic” and “raw”? Turns out that completely chemical free products isn’t so easy. But that's all about to change.



Introducing Lapka, a cool way to transform your iPhone into a “personal environment monitor”. Using a combination of apps and sensor attachments, it detects info from food wrappers and tests for “organicity.” Below is a demonstration courtesy of Mashable:



As explained in the video, the sensors are used to detect nitrate concentration, a chemical found in non-organic fertilizers. If it senses this, that means the food you're about to buy is a fraud. As for the app, it will collect snapshots from your phone of particle or food read outs to keep in a diary or share with others.

Currently Lapka is still in its prototype phase, but with more manufacturers and food retailers claiming to be "green", this might make stores start thinking twice before they make such claims.
