How does Krovium work?

Krovium puts Earth’s natural frequency back into the room you share. It emits a fixed 7.83 Hz, commonly known as the Schumann frequency. This is the natural frequency produced by the Earth. The field works on the room itself, so there’s nothing to wear, listen to or refill. No sound, no headphones and no app. Place it in your room, switch it on, and let it run quietly in the background while you sleep, work or unwind. It covers about 190 sq. ft, roughly one room, and it’s built for the hours most of us spend indoors.

I've tried everything. How is this different?

Because almost everything you've tried works on the body: something to wear, something to sniff, something to swallow. Those things can help for a while, then fade. Krovium doesn't touch anyone. It works on the room itself, quietly, in the background. There's nothing to wear off, nothing to refill and nothing to remember.

Does it really put out 7.83 Hz?

Absolutely, every Krovium is set to a single fixed frequency: a stable 7.83 Hz with no meaningful drift, and we've confirmed it through accurate measurement tests. Not every generator can say that. Many cheap knock-offs have been measured running well off-frequency.

Is it safe around my pets and kids?

Absolutely. Krovium is silent and battery-powered, with no heat, no scent and no light show. There's nothing for your pets or kids to accidentally swallow, put on themselves or touch.

Do I need one in every room?

Each Krovium covers about 190 sq ft, roughly one room. Most people start with the room they share most, often the living room or the bedroom. Many add a second for their pet's safe spot. That's why we offer 2- and 3-packs.

Homes that finally switched off

Real homes. Real pets. Real nights. Here's what people noticed.

A little less stress on stormy nights
Sophie Bennett with her rescue dog
My rescue dog used to shake and hide under the bed every time we had a bad storm. I'd tried a ThunderShirt, calming treats and even playing relaxing music, but nothing seemed to make much difference. I came across Krovium while reading a discussion in a dog owners group and decided to give it a try. I wasn't expecting miracles, but during a recent storm he seemed to settle a little sooner and spent less time hiding. It was such a relief to feel like we were making some progress.

It's like magic, I feel amazing
Working shifts left me exhausted, but getting my brain to switch off at night was another story. I'd tried herbal tea, sleep playlists and putting my phone away earlier, with mixed results. I stumbled across Krovium while researching different wellness products and was drawn to how simple it sounded. You just set it up and leave it running, rather than adding another complicated routine. I've found it easier to settle on some evenings since making it part of my wind-down time. I swear it's like magic, I now have one less thing to fuss over haha. Donna Hayes · Verified buyer
Finally, peace and quiet
Elaine and Jack with their dog
Whenever a storm or fireworks started, my dog would pace around the house, and we'd spend the whole time trying to comfort her. We'd put on calming music, sit beside her and try different products, but we were getting anxious myself before the thunder had even started. We came across Krovium while looking for other things pet owners had tried. What appealed to us was that it didn't add another task during an already stressful moment. It's kinda a win-win situation too, the Schumann frequency from the Krovium is good for both us and the dog. We'll definitely be buying another one for the house. Elaine & Jack · Verified buyer

Your home has gone quiet

Outdoors
Indoors

Outdoors, Earth's heartbeat is all around you. Indoors, the house goes quiet. Krovium brings it back into the room.

You've probably blamed yourself. Not enough discipline. Too much screen time. A dog you couldn't train out of it.

But look at how we actually live now. We spend around 87% of our lives inside buildings. Our pets do too. Most days, neither of you spends more than a few minutes truly outside.

For almost all of history, every living thing grew up surrounded by the natural world: its light, its air, and the steady 7.83 Hz pulse of the Earth itself, often called Earth's heartbeat. Today we live behind walls, under artificial light, surrounded by screens and wiring.

We call this Indoor Drift: the slow, quiet slide of modern life away from the natural rhythm we grew up with. And it might explain why so many fixes only ever work for a little while.

Wraps, sprays, collars, supplements and sleep apps all work on the body. None of them changes the place you live in.

The 1960s bunker experiment almost nobody talks about

In 1964, Max Planck Institute scientists built an underground bunker with one room shielded from natural electric and magnetic fields. Volunteers lived there with no clocks or daylight, and in the shielded room their daily body rhythms drifted to anywhere from 12 to 56 hours. Switching on a weak field shortened them back toward a normal day, on average.

Think of the nights you can't switch off, the days you feel wired but tired, the dog who can't settle when a storm rolls in. What if the rooms we live in have something to do with it?

Introducing Krovium

Krovium is a small, silent device that fills a room (around 190 sq ft) with the Schumann frequency, a steady, fixed 7.83 Hz signal, for up to a month per charge.

The Schumann frequency is a natural pulse of about 7.83 Hz that circles the Earth, created by lightning and often called Earth's heartbeat. Every living thing grew up with it. Indoors, where we now spend most of our time, we're cut off from it.

Krovium puts the Schumann frequency back into your room, giving your nervous system and your pet's their natural anchor again. It works on the room, not the body, so everyone is included with nothing to wear, plug in or stress over. Your dog gets calmer storm and fireworks nights and settles better when you're out; you get a quieter mind at night, easier sleep, and less of that wired-but-tired feeling.

One frequency. Measured. Shown.

Most frequency devices ask you to take their word for it. We don't.

Every Krovium is set to a single, fixed 7.83 Hz, and we've confirmed that it holds so you can rest easy knowing it's working how it should: stable, with no meaningful drift.

We kept it to one frequency on purpose. No channels to scroll through, no settings to get wrong, no wondering whether you picked the right one. Just Earth's natural 7.83 Hz, steady, all day and all night.

Give it time. That's why you get 60 days.

We won't promise you a miracle by Tuesday. Every home is different, and every pet is different.

People using natural-rhythm products describe noticing things anywhere from a few days to a few weeks in. Some notice small things first: where their pet chooses to nap, or how the evenings feel.

That's exactly why your guarantee lasts 60 days, not 30. Long enough for real life to happen: a few storms, a few nights alone, a few weeks of ordinary evenings.

Your first 60 days with Krovium

  1. Day 1

    Switch it on.

    Place it in the room you share most, or your pet's safe spot. That's all.

  2. The first few weeks

    Just live.

    No routine to follow. Notice where your pet chooses to rest, and how your evenings feel.

  3. The next storm

    Compare.

    Think back to the last storm or fireworks night, or your last sleep. What's different?

  4. By day 60

    Decide.

    Keep it, maybe getf one for another room. If it doesn't fit your needs, it's on us.

More questions

How long does the battery last?

Up to a month on a single charge. When it's time, plug it in with any USB-C cable.

Isn't this just another source of EMF?

Krovium runs on a battery at very low output, 0.3mW, with no WiFi, no Bluetooth and no app. It doesn't plug into the wall, and it has one on/off switch and nothing else to manage.

Can I use it with a ThunderShirt, diffuser or grounding sheet?

Yes. Krovium doesn't touch anyone and doesn't plug into anything, so it sits quietly alongside whatever you already use.

What if I don't feel anything?

Many people don't "feel" anything at all. Krovium is silent and still. Instead of waiting for a sensation, watch what you can see: how your pet behaves during the next storm, where they choose to rest, how your evenings go.

Why not just spend more time outside?

We'd love that for you. But most of us already spend around 87% of our lives indoors, and the weather doesn't always cooperate. Krovium brings Earth's natural rhythm to where you actually are.

Do I need one in every room?

Each Krovium covers about 190 sq ft, roughly one room. If you want the same calm in more than one space, you can place one in each room you share.

What if mine arrives faulty?

It's covered by the same 60-day money back guarantee, with nothing to send back. Our support team is available 24/7.
