99%
01
Blocks radiation where it matters
It covers the side of your phone that faces your body — pocket, ear, or nightstand.
02
Zero signal loss
Sits away from the antennas. Calls, data, and Wi-Fi work exactly as before.
03
Lasts the phone's lifespan
0.4 mm thin. Apply it once — it works under your case for years. No charging, ever.
How it works
Shielded in 30 seconds.
Step 01
Clean
Wipe the back of your phone clean and let it dry for ten seconds.
Step 02
Peel & place
Peel the backing and center the patch on the lower half of your phone — the zone closest to your body in a pocket.
Step 03
Press & forget
Press firmly for five seconds. The adhesive fully cures in an hour and holds for years — even under a case.
Tested in a certified labSee the full lab data
Almost nothing gets through.
We fire the same signals your phone uses at the patch and measure what makes it through. Less than a fraction of one percent.
Think of it like sound — the difference between a concert speaker and a whisper across the room.

Trusted across North America.
“Grabbed the buy-2-get-1 bundle for my kids' phones. What sold me was the published lab data — no other brand I looked at showed actual attenuation numbers.”

“It's thin enough that my MagSafe case snaps on over it and wireless charging still works. Clean design too — honestly it makes the phone look better.”

Questions, answered.
Will it affect my signal or battery?
No. The patch sits away from the antenna windows. Across 40+ phone models we measured no change in signal, data speed, or battery.
Does it work with a case and wireless charging?
Yes. At 0.4 mm thin it fits under virtually all cases, and Qi wireless charging works normally.
How is the 99% measured?
In an accredited RF chamber we compare signal power through the patch versus without it. Peak 42 dB attenuation is over 99.99% of energy stopped. Full methodology is on our Technology page.
