The walk to your car after a late shift. A quiet street on the way home. That unfamiliar city where you don't yet know which way is safe. The Monowander Personal Safety Alarm puts a 135dB siren and SOS strobe light on your keyring — loud enough to stop someone in their tracks and turn every head on the street.
One pull of the pin and it sounds instantly. No app to open, no battery anxiety, no fumbling when seconds matter. Small enough to clip to your keys, bag or belt loop — and rechargeable, so it's never dead when you need it most. It's the quiet confidence that lets you go anywhere and feel completely in control.

135dB emergency siren — heard from over 600 feet away, loud enough to draw attention from the next street

An ear-splitting siren and flashing SOS strobe fire instantly, drawing every eye on the street straight to you.

When you'll reach for it
This isn't just a travel gadget. It's the small thing in your hand on all the ordinary days too.
The late walk home. Down a quiet street, keys in hand, that instinct to have something ready — just in case.
The empty car park. After a late shift or a night out, crossing an empty lot to your car.
The solo run. Early mornings, dark evenings, headphones in — one hand always covered.
The new city. Somewhere unfamiliar, where you don't yet know which streets are safe.
The rideshare. Alone in the back of a stranger's car, phone at 12% — no app needed, it just works.
Every day, quietly. Clipped to your bag, doing nothing — until the one moment you're glad it's there.
Made for the moments that matter
The dark walk. The daughter you worry about. The confidence to go anyway.
For the walk you shouldn't have to worry about
The dark car park after a late shift. The quiet street home. Clip it to your keys and take back the walk that used to make your stomach tighten — 135dB and one firm pull away from turning every head on the street.
The safety you wish you could pack in her bag
Sending a daughter to college? A sister travelling alone? This is the small thing that lets you breathe easier. No app to set up, no subscription — just real protection she'll actually carry, every day.
Walk like the street is yours
It's not just about safety — it's about confidence. Knowing you're one pull away from help changes how you move through the world. Head up, shoulders back, going wherever you please, whenever you please.

Questions, answered
How loud is 135 decibels, really?
About as loud as a jet engine at close range. It can be heard from over 600 feet away — far enough to draw attention from the next street, and loud enough that most people instinctively look.
Do I need an app or a subscription?
No. The alarm works entirely on its own. Pull the pin and it sounds. There's nothing to set up, nothing to pair, and no monthly fee.
What if I set it off by accident?
Push the pin back in and it stops immediately. It takes a deliberate pull to trigger — it won't go off rattling around in your bag.
How long does the charge last?
Weeks of standby on a single USB charge. Charge it once a month and forget about it — no batteries to die at the worst moment.
What if it's not right for me?
Return it within 30 days for a full refund, provided it's unused and in its original packaging. No arguments.
Your safety. Your freedom. Everywhere.
