Which areas need support and which ones are working under extra load.
what you can do to help your body work properly.
The system is built to be useful for both specialists and everyday users. You get detailed analysis data, along with simple and clear recommendations.
The organ that most often shows the greatest imbalance needs the most attention.
In 1950, Japanese physician Yoshio Nakatani, while examining patients with kidney disease, noticed that certain areas of skin on the wrists and ankles conducted electricity significantly better than adjacent areas.
This pattern was repeated in each patient, and he mapped it. The method was named Ryodoraku (良導絡) - "highly conductive pathways." Since then, it has been studied and used in Japan and Korea.
RaDoTech measures 12 points on each side of the body and give you a whole-body condition in one picture. You get numbers, graphs and a color map.
Plus simple recommendations on nutrition and supplements that will allow you to stop wondering "what's wrong with me" and instead act with complete confidence and understanding.
Currently, RaDoTech is the only device that lets you scan 12 body systems on your own, without a Ryodoraku specialist, in just two minutes, with results available immediately.
The measurement current is 200 microamps, a thousand times lower than the threshold of human perception. The scan is COMPLETELY SAFE for children and people with pacemakers.
RaDoTech is a bioelectric acupressure scanner. In just 2 minutes, it shows a simple chart: which organs show up as overloaded, which as underactive, and which as balanced.
Instead of guessing where to start when you feel tired, weak or unwell, you see which organ shows up as underactive, highlighted in blue. That's where your care should go first.
Seeing blue on your chart isn’t a reason to panic. It’s a reason to act.
The real problem is not knowing: most people never find out, so they never change a thing. Years of short sleep, sitting all day and eating on the run don't just leave you tired. They're behind many of the chronic diseases people end up treating later in life. The good news is that simple daily changes are among the best-proven ways to lower your risk, and supplements can help fill the gaps in your diet. And it's a lot easier to start when you can see where.
To be upfront: RaDoTech is not a doctor. It doesn't diagnose or treat disease.
A story many of our customers will recognize.
Meet Mark. He's 44, and his nights look like this: leg cramps at 2 a.m., tossing and turning, waking up more tired than when he went to bed. He's exhausted every day - and can't figure out why.
After a RaDoTech scan and a consultation, the picture got clearer: his magnesium levels might be the missing piece.
So he started Magnesium + B6. Within a few weeks, the cramps eased off, he was sleeping through the night, and his days finally had energy in them again. He even felt calmer.
“I finally sleep through the night and feel like myself again.”

Marina’s first scan. Kidney meridian, both sides: 15% and 10%.*
*RaDoTech doesn’t diagnose disease or measure kidney function. Worried about your kidneys, or have high blood pressure, diabetes or a family history of kidney disease? Ask your doctor for blood and urine tests.
Marina, 33, lives on a loop: gym at six, ten hours at work, dinner at red lights. Her lifts haven’t moved in a year, her rings won’t come off before her period, and cramps steal two or three days a month.
Her first scan, in the gym parking lot, showed one line below the norm on both sides: the kidney meridian.
In Eastern medicine, the kidney meridian is less about the organ than about the body’s reserves: stamina, recovery, water balance, a woman’s cycle. A low line means the body has been spending more than it gets back. The app’s recommendations were simple: real meals with probiotic foods, RenActive to support the kidney system, and Wild Yam for the cramp days.
So Marina rewrote the loop: Sunday meal prep, yogurt and kimchi, more water, RenActive and Wild Yam. By week eight, the kidney line was in the green. Her rings slide off again, cramps cost her one day, not three, and she hit her first deadlift PR in over a year.
The hardest part of taking care of people isn't treating them. It's figuring out what's happening in the first place.
Your six-year-old says his tummy hurts and points vaguely at his middle. That could be anything from "ate too much" to "doesn't want to go to school."
Your fourteen-year-old answers every question with "I'm fine." He's also not sleeping, snapping at everyone, and his skin got worse. Hormones? Phone at 3 a.m.? Something real?
RaDoTech is based on Ryodoraku technology, which links both skin health and mood to the spleen-pancreas system.
Weakness in this system is associated with “dampness,” meaning oily skin and acne, as well as anxiety and endless rumination.
RaDoTech measures, not affects. The current is 200 microamps: a thousand times lower than the sensory threshold and does not affect pacemakers or other electronic implants. It feels like touching a phone screen.
No needles, blood, radiation, or preparation. Therefore, the same device can be safely used by both a six-year-old child and parents over seventy.
The scan takes two minutes and requires nothing more than water on your palms and soles.
The blue-red zone is a good time to talk and, if necessary, see a pediatrician with a specific question, not just a simple "something's wrong."
The green zone is a time to breathe a sigh of relief.
"It has alerted me to look more closely at systems I may have overlooked."
Camilo Sanchez, L.Ac., MAOM - 35 years in acupuncture and integrative health, 3Nergy Wellness
"Much faster and easier to use than any other Ryodoraku device I have used."
Dr. Daniel G. Callahan, DAOM - Clinical Supervisor and Instructor, Midwest College of Acupuncture
"As a doctor, I was very skeptical at first. It is simple, reliable and it works."
Dr. Vladimir Yagodkin - Pediatrician
RaDoTech is FDA registered.
RaDoTech PRO - $1,087. 20 client profiles included, no consumables, scanning takes two minutes between clients.
If you include scanning in your $30 appointment, the device will pay for itself in 37 scans. If you use the scan results to sell a supplement course or program, it's faster.
What does this provide besides money? The client sees a colored map and understands why you recommend it. A month later, they see that the area has turned green. These clients don't argue with the recommendations and return.
The app has a separate section for practitioners (TCM, Ryodoraku) - it shows all the measured values, not just the colored map.
RaDoTech PRO is designed for testing other people. A long cord makes it easier to work with clients, and reinforced components make the device more durable under constant use.
Tests faster. The professional version tests faster than a personal device - with a high volume of clients, this saves time during each appointment.
Hard case included. A practical zippered case for transporting and storing the device.
20 profiles available immediately and can be expanded without limitation. The kit includes 20 client profiles; additional profiles can be purchased as needed. Profiles are paid for once and do not require renewal.
FDA RaDoTech
Yes, RaDoTech is FDA-registered. It is not a diagnostic device and does not diagnose, treat, or cure any condition — it's designed to give you a general wellness check-in.
RaDoTech is a pocket-sized wellness tracker that measures skin conductance at 24 points on your wrists and feet and turns the readings into an easy-to-read body-systems map in a free app. A full scan takes about 2 minutes, so you can check in at home as often as you like and see how your readings respond to sleep, food, stress and training.
Each scan is a snapshot of how your 12 body systems are reading at that moment, compared with a normal range. You'll see which systems read strongest and weakest, how balanced your left and right sides are, and five summary indicators the app calls energy level, immunity, metabolism, psycho-emotional state and musculoskeletal system.
The real value is the trend. Scan again after a change in habits, a course of treatment, a stressful week or a holiday, and see how the picture shifts.
Results arrive in the app in real time. You get a color-coded body map (green within the normal range, red above it, blue below it), a percentage score for each system on the left and right side, and detailed charts. You can tag each scan, browse your full history and email yourself a short or full PDF report.
It depends on your goal. For a general check-in, once or twice a week is plenty. When you're testing a change, such as a new diet, training block or sleep routine, scan daily or before and after, so you can see the effect.
There's no limit on the number of scans and no cost per scan, so the whole family can check in as often as they like.
Consistency matters more than the exact time of day. A few habits make your trend much clearer:
Because your body does. Readings respond to sleep, stress, meals, hydration, exercise and time of day; conductance at these points naturally rises from morning to afternoon. That's exactly what makes RaDoTech useful: it shows how your body reacts to your daily life. Look at the trend across several scans taken in similar conditions, not at any single number.
Your smartwatch tracks what your body is doing: steps, heart rate, sleep. RaDoTech adds a different kind of signal that wearables don't capture: a 24-point conductance reading, interpreted through the Ryodoraku method.
Many owners use both: the watch for daily activity, RaDoTech for a quick check-in on how their body systems are responding. RaDoTech doesn't measure heart rate, blood pressure or temperature, so it complements those devices rather than replacing them.
Yes. Create a profile for each person, then use assistive mode: they hold the device's metal body while you place the probe on their points. Just don't touch their skin while a point is being measured. Each person's history stays in their own profile, and RaDoTech Pro has a longer cable designed for scanning others.
First, rescan. An unusual single reading is often caused by a missed point, dry skin or too little pressure. If a reading stays far outside the normal range over several days, treat it as a prompt to check in with a healthcare professional, not as a diagnosis. You can also email your results to our team or book a consultation to talk them through.
Yes. You can email a short or full PDF report straight from the app, or log in to your web account and export results there. Many people bring their trend to appointments as a starting point for a conversation about habits and progress.
You don't have to choose. A check-up with your doctor gives you a detailed medical picture once or twice a year. RaDoTech fills the months in between with a 2-minute check-in you can repeat weekly or even daily, so you notice how your habits affect you while they're still easy to adjust. Bring your trend to your next appointment if you'd like to discuss it.
No. RaDoTech is built for everyday use. Just follow the instructions on your screen — most people feel confident after 2 to 3 practice tests.
RaDoTech connects through the free RaDoTech app over Bluetooth. Make sure Bluetooth is turned on, and on some Android devices, Location also needs to be enabled for the connection to work. RaDoTech won't pair through your phone's regular Bluetooth settings — the app handles the connection automatically when you start a test.
RaDoTech is based on Ryodoraku, a method of measuring electrical conductivity at specific points on the skin, developed by Dr. Yoshio Nakatani. RaDoTech measures this conductivity and charts it in an easy-to-read format, so you can see how your body's systems compare to a healthy baseline and track changes over time.
Yes. RaDoTech uses a very small 200 microamp electrical pulse, around 1,000 times lower than a level you could feel. It has no effect on pacemakers or other electrical implants, doesn't emit radiation, and is safe for the whole family.
RaDoTech Normal includes 5 profiles. RaDoTech Pro includes 20 profiles from the start, with expansion packs available for practices testing more people.
Yes, RaDoTech comes with a 12 month warranty.
You'll need an internet connection for new scans to be analyzed and synced to your account. Results you've already synced can be viewed offline.
