The technology

It listens. It never
speaks.

The critical difference between the Ova Meter and every other EMF monitor on the market is what it doesn't do. It emits nothing. No Bluetooth, no RF, no wireless signal of any kind. It is a receiver only.

Plug into any wall socket
The Meter draws power from the socket — no batteries, no charging. It powers on immediately and begins measuring the electromagnetic environment in the room.
Connects via your home Wi-Fi
A one-time setup in the Ova app connects the Meter to your router. After that it communicates through your existing network — the Meter itself emits no wireless signal to do this. Your router does the work.
Measures RF and ELF continuously
Every 15 minutes, the Meter takes a reading of both RF (radio-frequency radiation from phones, Wi-Fi and 5G) and ELF (extremely low-frequency fields from wiring, smart meters and appliances). Two types — because most devices only cover one.
App builds your family's picture
Readings flow to the Ova app where they're processed on-device into per-member exposure reports, trend analysis and personalised insights. Nothing leaves your phone.

Detection range

Two types.
Most cover one.

The vast majority of EMF monitors only detect RF radiation — the kind from phones and Wi-Fi. The Ova Meter detects both RF and ELF. That matters because the wiring in your walls, your smart meter, and your appliances all emit ELF — and it's completely invisible to RF-only devices.

ELF Fields
Extremely low-frequency · 50 – 60 Hz
The magnetic fields emitted by electrical wiring, appliances and power infrastructure. Invisible to RF-only meters and largely ignored by competing products — but present in every home.

The privacy promise

The meter listens to
the room. Not you.

We know what you're protecting your family from. We would never become part of the problem. Here is exactly what the Ova Meter does and does not do with data.

Readings processed on your phone
The Meter sends readings to the Ova app on your device. All processing happens locally — Ova never sees your readings.
Wi-Fi password stored only on device
Your network password is saved on your phone to pair the Meter. It is never sent to Ova or any third party.
No Bluetooth emitted — ever
The Meter communicates only via your existing Wi-Fi router. It emits no Bluetooth signal of any kind.
No data stored on Ova servers
Readings are never uploaded or stored externally. If you delete the app, all data is gone permanently.
"The meter listens to the room. Not you.
Not your family. Not your home."

What families discovered.

The Meter changes how families understand their home. These are the moments that made the difference.

"The router was spiking to HIGH every evening. Moving it two metres made the reading drop to LOW overnight. We never would have known without the Meter."

"I had no idea ELF fields were even a thing. The Meter flagged elevated ELF every morning in the nursery — turned out it was the extension cable running under the cot."

"The design is genuinely beautiful. Matte ceramic in Forest just sits on the shelf. No one notices it isn't a diffuser or a speaker. It is completely discreet."
