“Text me when you're home” is not a safety plan.

So we built one. One pull of the Siren unleashes an alarm louder than a police siren, a strobe you can see down the block, and an instant SOS to your people with your live location.

Pull the pin. Everything happens at once.

Sound, light, and the people who love you, all in the first second.

130dB siren

Louder than a car alarm and heard a block away. Threats count on your silence. One pull takes it away.

Flashing strobe

A flashing beacon makes you impossible to miss, even in the dark. One press gives you a steady flashlight for the walk itself.

We are not being dramatic. The numbers back us up.

The habits we call normal, the check in texts, the shared locations, the keys held just in case, exist for a reason. This is what the research says about being a woman out alone.

A man started following me too closely one evening and I pulled the pin. He immediately backed off and left.

I'm so grateful I had it on me. This isn't just a gadget, it works.

Every girl on my campus has one now

I don't leave my dorm without it. Half my flat has bought one since they saw mine.

Essential for my late shifts

I'm a nurse and walk to my car alone after night shifts. Keys in one hand, alarm ready in the other. It's the most reassuring thing I've bought in years.

Peace of mind on my morning runs

I run alone before sunrise and this fits right in my hand. It's the first thing I grab heading out the door.

Bought one for me and my daughter

Setup with the app took two minutes and now I get her live location if she ever triggers it. Worth every penny for the peace of mind alone.

Feel safe showing houses alone

I'm a realtor and often meet strangers at empty properties. It's discreet, but the siren is anything but.

GuardHer founder

We didn't design this in a boardroom. We designed it for the walk we all know.

GuardHer is women building for women. We live the same rituals you do, the shared locations, the check in texts, the keys held just in case. Every detail, from the one pull activation to the family alert, exists because we wished it already did. One product, made carefully, backed for life.

The questions we asked too

Can I take it on a plane or to campus?+

Yes. Unlike pepper spray, the Siren is legal everywhere: TSA friendly, dorm approved, stadium safe, worldwide.

How does the family alert work?+

Pair the Siren with the free app once. Press the SOS button and your chosen contacts get an instant notification with your live location, and can navigate straight to you. No subscription required.

How long does a charge last?+

Months on standby from a single USB charge. The charge indicator shows you it's ready at a glance, so there's never a 'did I charge it' moment on your way out the door.

How loud is it, really?+

Louder than a rock concert, a chainsaw, or a scream. It carries roughly a city block, far enough to draw attention when it matters most.

Will it actually scare someone off?+

The Siren is an attention tool, not a weapon. Threats rely on silence and isolation, and the alarm removes both, drawing every eye and ear toward you while the app alerts your family. It makes you the loudest, most visible person on the block.

Does it work without the app?+

Yes. The siren and flashlight work completely on their own, no phone and no pairing. The app is optional and adds the family SOS alert with live location.

How do I turn the alarm off?+

Push the pin back in and the siren stops instantly. If it ever goes off by accident, you're one second from silence.

How big is it?+

Smaller than a lipstick and light enough to forget. It lives on your keys, bag strap, or backpack with the included carabiner clip.

Is it suitable for kids, teens, or older family members?+

Yes, that's the point of one-pull activation. No strength, no training, and no fine motor skills under stress. If they can pull a zipper, they can use a Siren.

What if I change my mind?+

30-day money-back guarantee, no questions asked. The only risk is not having it.
