We’d like to introduce you to NOTA – a surprisingly effective app-powered mole tracker. NOTA works by measuring the electrical impedance of moles on your skin.

It is actually a little known fact that moles and tumors have a very different electrical impedance – this is what allows NOTA to work, and track changes in your body over time.  

Besides the electrical impedance, moles and melanoma have several notable differences.

Moles (or the medical term: Nevi) are pigmented skin formations that vary in color and can be brown, black, red, or purple (though rarely more than one color).

Those moles that show up after sunbathing, start itching, or have grown and/or changed color should be taken seriously and checked.

Melanoma causes a large majority of skin cancer deaths, and can develop out of ordinary moles in response to UV light, injuries, or even rubbing.

The American Cancer Society’s estimates about 100,350 new melanomas will be diagnosed in the United States during 2020. Of those, 6,850 are expected to be fatal. The rates of melanoma have been rising rapidly over the past few decades.

A true melanoma can only be confirmed by healthcare specialists, and it’s important to do as early as possible, as late-stage diagnosis may lead to severe consequences.

That’s why monitoring your moles is vital. Before, you were only able to do it by paying close attention to any changes in your moles. NOTA is the most accurate and convenient way to track your moles.

Normal tissue and tumors have different amounts of water in them, which leads to differences in bioimpedance: a measure of how well the body impedes the flow of an electric current.

As long as the cell contents are normal, NOTA will show a green light. When the light turns yellow or red, this indicates abnormalities and changes in your mole.

The mobile app allows you to track your moles and any changes over time. It also offers regularly updated health information on skin, moles, and how to properly care for them. 

NOTA is designed to fit into your everyday routine. Just like an at-home thermometer, you can use NOTA to check any changes in your moles whenever you are concerned, or at regular intervals.

NOTA is a collaboration between engineers, entrepreneurs, scientists and designers who are dedicated to creating portable devices that improve people’s lives from the palm of their hand. We bring together a vast collective of professional experience from many industries, giving us the creativity to create truly inspiring, world-changing smart gadgets.

We believe every marker of health should have its own “thermometer” equivalent, an at-home detection device that is simple and easy to use. By bringing these devices into existence, we are helping to create a healthier world.

NOTA was developed over a rigorous 2-year period, with several prototypes and scientific validity testing. We initially determined the types of sensitive electrodes we would need to measure impedance in the skin, then focused on simplifying them into a single device.

From there, we streamlined the design into something anyone can use at home. Now, the NOTA is a remarkably accurate hand-held medical device capable of providing possible early warnings for those with a risk of melanoma.

Throughout the year we’ve been conducting studies in cooperation with doctors and their patients. We’ve collected data on thousands of moles’ resistance to teach the neural network to recognize anomalies.
