The Ova system
Three things. One promise.
Everything Ova makes works together — beautifully, quietly, without contradiction. The blanket attenuates. The meter measures. The app gives you clarity.

How Ova works
Passive. Intelligent. Honest.
No wireless in the blanket. No data on our servers. No contradictions — ever. Here is exactly how Ova works.
01
The blanket attenuates
EcoShield™ silver-fibre creates a measurable Faraday layer. No chip, no battery, no emission. Pure physics — conductive thread reducing RF field intensity through the fabric.
02
The meter measures
Plugged into the wall, the Ova Meter reads RF and ELF field levels continuously. Connects to your app via your existing router. Emits nothing itself.
03
The app contextualises
Live Meter readings, outdoor 5G tower data, and ICNIRP reference levels combine into clear weekly reports. One for each family member. Everything on your phone.
04
You stay in control
Your family data lives only on your device. Location is never stored. No advertising. No third-party sharing. Ova's promise is published openly — not buried in small print.
Evidence & performance
Not a claim. A measurement.
Every performance figure on this site is derived from physical measurement. Here is what we test, how we test it, and what the numbers mean.
RF attenuation testing
Each production batch is independently tested for attenuation performance across 30 MHz–3 GHz using a calibrated signal generator and spectrum analyser. Results are logged per batch. Performance must hold above 20 dB after 50 wash cycles.
Up to 30 dB
RF attenuation · 30 MHz – 3 GHz
Live meter demonstration
We test with a calibrated RF meter in a real home environment — not a shielded lab. You can see exactly the same test using any consumer RF meter. The physics is transparent and reproducible by anyone.

Material certification
EcoShield™ silver-fibre carries OEKO-TEX Standard 100 certification — independently audited for chemical safety in direct skin contact applications. CE marking confirms compliance with EU textile safety requirements.

What we measure and state
RF attenuation in dB — a measurable engineering property of the fabric
RF and ELF field levels in your home, measured against ICNIRP reference levels
Material composition and certification — independently audited, not self-declared
What we do not claim
That everyday RF exposure at current levels causes health harm — mainstream evidence does not establish this
That Ova prevents, treats or reduces risk of any medical condition
That you need Ova — this is a choice about your environment, not a medical necessity
The privacy promise
The only environmental monitoring app that doesn't track you.
We build tools that help families understand their environment. We would never undermine that trust ourselves.
All data on your device
Every reading, report and family profile lives locally. Raw data never leaves your phone.
Location processed locally
GPS used on-device only to look up cell towers. Never stored, never sent to Ova.
No advertising — ever
Ova has no ad partners. Your data will never be used to target you with ads by anyone.
No children's data collected
Family profiles including children's names and ages never leave the device, ever.
"You choose to understand your family's environment. We make sure that choice stays entirely yours."

From Ova families
What parents say.
★★★★★
"I didn't expect the app to change how I think about our home. Seeing Aaryan's exposure drop week by week genuinely made me feel like a better parent."
Sarah M.Mother of two · London
★★★★★
"The unboxing alone convinced me this was different. The blanket is genuinely beautiful — it's on the bed during the day. It doesn't hide."
James K.Father · Edinburgh
★★★★★
"The privacy promise was what sold me. Other apps want your data. Ova is the first one that actually means it when they say they don't."
