Lapka is a series of four interchangeable sensors that allows your iPhone to measure how organic a food is. Users simply plug in the device through the smartphone’s headphone jack, and then lightly poke the food with the steel probe. The detector works alongside a special app to check for nitrate concentration, a chemical commonly found in fertilizers that are used on non-organic farms and in non-organic environments.

Not only can Lapka measure how organic something is, but it can also detect real-time radiation levels, electromagnetic field (EMF_ levels, and even humidity levels. The device is also stylish, made from wood and ivory plastic that aligns with Apple’s minimalistic designs. Lapka is still a prototype but expects to be launched at the end of 2012, with a retail price of $220.
