Congratulations — Your RaDoTech Has Arrived

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.

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 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.

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 gives you a snapshot of your body's systems, showing which are reading strongest and which are reading weakest at the time of your test. Run it again later and you can see how those readings have changed, whether that's after a change in habits, a course of treatment, or just over time.
