How sensitive are you? Want to find out?

For the first time ever you can discover exactly how sensitive you are.

Take the Sensitometer™ test. It’s easy, accurate and science-based.

Nearly 40% of adults and children are overly sensitive. They experience headaches easily when exposed to sunlight, fluorescent lights, perfume, irritating odors, cold air, cigarette smoke, exhaust fumes, and small changes in hormone levels.

If your body over reacts to changes in humidity, cold air, pollution or changes in your hormones, you may be hypersensitive.

How does the Sensitometer™ test work? It’s a two-step process.

First, we use clinical information you provide by answering ten easy questions about how you feel, which reveals your own unique Degree of Sensitivity.

Next, we use the upgraded video camera in your iPhone or iPad Pro* to measure exactly how fast your eyes react to the light in your camera. We record the speed of your pupils’ reactions and mathematically analyze your unique response times.

You will see your Degree of Sensitivity on your iPhone screen soon after taking the test.

Hypersensitive people are not crazy. They are Hypersensitive to anything that changes inside or outside of their bodies.

Are you hypersensitive? Take the Sensitometer™ test and share your unique Degree of Sensitivity with your family, friends and personal physician.
