  • Sure, stores say produce is organic but there are varying levels and do you want to simply rely on their word? The Organic Sensor from Lapka is a simple solution for quickly determining if raw fruits and vegetables are truly organic as it measures the concentration of nitrates that are left behind in the food that are a result of using nitrogen-based fertilizers; the smaller the quantity the purer the food. The sensor works by connecting it to your iOS device (iPhone 4 and higher, iPad, iPod Touch 3rd generation and higher) with the included cable, opening the free app and simply sticking the probe into the food you wish to test. Results will then be shown on the app interface to let you know the food temperature and concentration of nitrate ions so you will have an accurate reading of how organic the food truly is. Save your data so you can keep track of the stores with the most organic produce and share your findings with friends and family. The Organic Sensor probe should be cleaned after each use to ensure an accurate reading of each individual fruit and vegetable tested.

    Currently the Organic Sensor setting on the Lapka app has the following preset fruits and vegetables with known nitrate content levels (more to come):
    • Apple
    • Melon
    • Onion
    • Potato
    • Watermelon
    • Cucumber
    • Celery
    • Banana
    • Tomato
    • Eggplant
    • Pumpkin
    • Strawberry
    • Carrot
    • Cauliflower
    • Broccoli
    • Lettuce
    • Corn

    • Lapka App
    • Ambient Mode - At the bottom of your screen you'll notice animated particles moving around that match the symbol of the sensor you're using. These are representations of every particle counted in your environment allowing you to visualize your environment in real time.

    • Diary - Saves your results. They'll be stored in your Lapka diary as little blocks, which you can access when a device is not plugged in. Give your iPhone a shake and the blocks will shift from device used to preset used to the type of result. You can review each moment you captured in an individual day or explore by month.

    • Share - There are various options for sharing your measurements. Email an office measurement to your employer who's thinking of getting some humidifiers for the workplace. Text a radiation result to a family member, letting them know you're safe and sound. Tweet about how fresh and delicious your apple is. Or simply choose to copy the result and paste it anywhere you feel like. When you share, a link is provided that brings you to a beautiful, animated visualization of the moment you captured. If your result is saved to your diary, you can always share it later.
