Bio-Well is a camera that sends a short high voltage pulse through your fingertip and photographs the glow. Software turns the images into energy, chakra and organ charts. It costs 2,299 dollars and does not work without a subscription of 25 dollars a month. Bio-Well says it is not a diagnostic tool, and an independent test in 2024 found the readings stayed much the same whoever was measured. ResoField is free software that measures nothing.
Bio-Well is a camera for your fingertips. You put a finger on a glass plate, the device sends a short high voltage pulse through it, and a camera underneath photographs the faint glow that forms around the tip. The software turns those images into colourful charts: an "energy field" around your body, chakras and organs. The method is called gas discharge visualization (GDV) and comes from the Russian physicist Konstantin Korotkov.
The device costs 2,299 dollars and does not work without a software subscription of 25 dollars a month. The glow is real and can be photographed. The question is what it tells you, and here the independent evidence is thin and mostly negative. Bio-Well itself says its device "should not to be used as a diagnostic tool". I have never used a Bio-Well; this review is based on Bio-Well's own pages, its device passport, the studies in PubMed and an independent test from 2024, all checked on 23 October 2026.
What Bio-Well is
Bio-Well, LLC is based in Louisville, Colorado. Konstantin Korotkov, who holds a PhD in physics from Saint Petersburg State University, is named as director of the Bio-Well companies and president of the International Union of Medical and Applied Bioelectrography. According to Bio-Well, his team developed GDV in 1995, and the current model, Bio-Well 3.0, came out in 2023. The trademark Bio-Well was first used in commerce in 2013.
The device passport names Orient Hero International Limited in Hong Kong as manufacturer and Energy Instruments and Software SL in Huesca, Spain, as producer.
How the GDV camera works
Under the glass plate sits an electrode. When you place your finger, the device applies a burst of 10 to 20 kV pulses, each lasting 10 microseconds, for half a second. That creates a tiny gas discharge, a corona, around the fingertip, and a camera under the glass records it. A metal cylinder is used to calibrate the device.
This is a refined version of Kirlian photography, which became famous in the 20th century for its "aura" pictures. Bio-Well describes its own technique as "rooted in Kirlian photography". The physics of the glow itself is ordinary. The leap Bio-Well makes is from the shape and brightness of that glow to statements about organs, chakras and energy.
What affects the image
A corona discharge reacts to many things that have nothing to do with health:
- Moisture. A study in Science in 1976 found that "most of the variations in the images of the corona of a living subject" could be explained by moisture on or in the skin.
- Pressure and position. How hard you press and where your finger lands on the glass change the picture, as independent researchers noted again in 2024.
- Room conditions. The passport gives an operating range of 18 to 35 °C at 30 to 70 percent humidity, Bio-Well calibrates to account for temperature and humidity, and the passport warns that a mobile phone nearby "may result in incorrect operation of the device."

Does Bio-Well work? The evidence
Bio-Well's product page mentions "400+ published studies". PubMed finds 27 papers with "gas discharge visualization" in the title or abstract, Korotkov co-authored 9 of them, and 5 mention Bio-Well. Many of the 400 are conference papers and articles in journals outside PubMed.
What the studies show depends on who did them:
- Korotkov and colleagues reviewed GDV research in 2010 and concluded that the method can be used to assess treatment effects. Korotkov was the first author, reviewing his own method. A 2015 study with him as co-author found differences in GDV readings between 56 people with tumours found at colonoscopy and 22 controls, and called for "a more in-depth study".
- An independent systematic review from India in 2023 looked at 42 studies and concluded: "More studies with a robust methodology are needed to make definitive conclusions."
- Many newer studies use Bio-Well as a measuring tool without testing whether it measures anything real. In one, the readings of 17 people changed after exposure to a "sacred stone".
The most direct independent test was published in 2024. A researcher at the California Institute for Human Science, without Korotkov, measured 40 people and water samples with both the older GDV device and Bio-Well. Readings for the same person varied by about 2 to 4 percent, but readings between different people varied by only 2 to 9 percent, while organ and chakra values swung by 214 and 358 percent. The conclusion: the parameters "showed large measurement variability and/or poor informative value", and "they tend to assume always the same set of values, regardless of the testees" (Miraglia, 2024).
Bio-Well answers that the device itself varies by no more than 2 percent on its metal calibration cylinder, and attributes the variation in people to their nervous system. That shows the camera is stable. It does not show that the charts say anything true about your organs.
Is Bio-Well a medical device?
No, and Bio-Well says so: "Is Bio-Well a diagnostic tool? No." The "Bio-Well CE Cert" on its website is a test of electromagnetic compatibility, the standard every electronic lab instrument needs, not a certification as a medical device. The FDA databases contain no Bio-Well or GDV device. Bio-Well also claims certification by Russia's Ministry of Health, which I could not confirm in the Russian device register.
Is it safe?
The pulse is short and the current is tiny, so the physical risk is small. As with every scan of this kind, the risk lies in the interpretation: a chart that shows a "weak" organ or a "blocked" chakra can worry you for no reason, or reassure you when you should see a doctor.
Bio-Well and other scans
Bio-Well is often mentioned in the same breath as electrodermal scans such as ZYTO and Asyra, although it measures something different. Our article on what bioenergetic testing measures covers that group, and our article on the quantum resonance magnetic analyzer covers the cheapest end of the market.
Where ResoField fits
ResoField takes no pictures and measures nothing. It is free browser software for practitioners: libraries for homeopathy, bioresonance and Rife frequencies, client profiles, your own lists and protocols. You choose every remedy yourself, for example with a muscle test or a biotensor. If you want an image of a client's "field", Bio-Well is the device people buy. If you want to organise and broadcast remedies without hardware, that is what ResoField does, for free.

FAQ
What is Bio-Well?
Bio-Well is a camera that photographs the glow around your fingertips after a short high voltage pulse, a method called gas discharge visualization. Software turns the images into charts of an energy field, chakras and organs. It is made for Bio-Well, LLC in Colorado and based on the work of the Russian physicist Konstantin Korotkov.
How much does a Bio-Well cost?
On 23 October 2026 the Bio-Well 3.0 camera cost 2,299 dollars, and the required software subscription 25 dollars a month or 275 dollars a year. The Starter Pack with 12 months of software and a course cost 2,999 dollars.
Does Bio-Well work?
The camera reliably photographs a glow, but there is no independent evidence that the charts say anything true about health. An independent test in 2024 found that Bio-Well readings stayed much the same regardless of who was measured. A 2023 systematic review called for more robust studies.
Is Bio-Well scientifically proven?
No. Most supportive studies involve Korotkov or use Bio-Well as a tool without validating it. Moisture, finger pressure and room conditions are known to change the image. Bio-Well itself says it is not a diagnostic tool.
Is Bio-Well the same as Kirlian photography?
It is a refined, digital version of it. Bio-Well describes its technique as rooted in Kirlian photography: both photograph the corona discharge around an object in a high voltage field.
Is Bio-Well FDA approved?
No. The FDA databases contain no Bio-Well or GDV device, and the CE certificate on Bio-Well's site covers electromagnetic compatibility only, not medical use.
Do I need a subscription for Bio-Well?
Yes. Bio-Well states that the device cannot function without an active software subscription, which costs 25 dollars a month or 275 dollars a year.
Is there a free alternative to Bio-Well?
ResoField is free browser software, but it does not take pictures or measure anything. It helps practitioners organise remedies, frequency lists, clients and protocols, and you make every choice yourself.
