Why families choose Senlo
The call every family dreads — answered in seconds
"Why didn't anyone call me sooner?"
A fall in the kitchen. A wrong turn on a familiar street. The hardest part is not knowing — the hours that pass before anyone realizes something is wrong.
Now you'll know right away
With one press of the Guardian button, your parent instantly calls and texts you and the whole family — with their GPS location. No more wondering. Just fast, calm connection when it matters most.
How it works
Ready in minutes, simple for life
No apps to learn, no contracts, no setup headaches. It arrives pre-configured and ready to protect.
1. Unbox & charge
Your Guardian arrives pre-configured with your family's numbers. Just charge it and it's ready.
2. Slip it on
Comfortable, lightweight, and water-resistant — your parent wears it like a watch, all day, even in the shower.
3. One press for help
If they ever need help, one press of the big SOS button instantly calls and texts the family with their location.
Why Senlo Guardian
Protection that's simple, honest, and always with them
Everything a family needs to stay connected — and nothing that gets in the way.
One-time payment, no monthly fees
Pay once and you're done. No subscriptions, no surprise bills — unlike traditional alert systems that charge around $40 every month, forever.
One big, simple button
No confusing touchscreen or tiny menus. Just one large, tactile SOS button that's easy to find and press — even in a stressful moment.
Two one-touch family buttons
One touch to reach the people who matter — press 1 for your daughter, press 2 for your son. No dialing, no screen.
Works anywhere
Built-in 4G and GPS mean it works at home, in the garden, at the shops, or on a walk — not just within range of home WiFi.
Alerts your family directly
One press instantly calls and texts the people who love them — with GPS location — so help comes from someone they trust, in seconds.
Set up in minutes
It ships pre-configured with your family's numbers. Charge it, slip it on, and it's ready — no apps to install, no contracts to sign.

Peace of mind, in their own words
Real stories from families who trust the Senlo Guardian to keep the people they love safe.
I'll be honest, I almost didn't order it. Mom's not great with gadgets and I figured it'd end up in a drawer like the last 'helpful' thing I bought her. But there's literally one big button — she got it in about a minute. Two weeks later she had a bad fall in the kitchen and pressed it, and my phone rang instantly with where she was. I was there in 10 minutes. I don't think I've exhaled properly since she started living alone, and now I finally do. Only small thing: I wish the battery lasted a month — it's more like 3 weeks, so I charge it every Sunday so I don't forget.
The 'no monthly fee' thing honestly made me suspicious — everything for seniors has a catch and a $40 bill attached. But there genuinely isn't one. Setup was easier than I expected, I put my number and my sister's on the 1 and 2 buttons, and Dad actually wears it because it looks like a normal watch, not a medical alarm. Knowing he can reach both of us with one press while I'm at work changed how I get through the day. Battery could be better — about 3 weeks, not a month — but that's my only complaint.
We had one of the big-name alert systems and I was paying every single month for something my mother refused to wear. This was a one-time cost and she actually keeps it on, which is the whole point. The night she got dizzy and couldn't get up, she pressed it and it called me before she'd even thought to panic. That feeling of getting to her fast is worth everything. I do wish the charge lasted longer than ~3 weeks, but it's a tiny price for the peace of mind.

Questions & answers
Everything you might be wondering
Is there a monthly fee or subscription? +
No — and this is what makes Senlo different. The Guardian is a one-time purchase with no monthly fees and no subscription, ever. You pay once and it's yours.
How does the SOS button work? +
If your parent needs help, they press the one large SOS button. The Guardian instantly calls and texts the family contacts you've chosen, and shares their GPS location so you know exactly where they are.
Does it work away from home? +
Yes. The Guardian has built-in 4G and GPS, so it works at home, in the garden, at the shops, or out on a walk — anywhere with cellular coverage. It is not tied to home WiFi.
Is this a medical device or a monitoring service? +
No. The Senlo Guardian is not a medical device and is not a professional monitoring service. It is a simple personal safety device that alerts your own family contacts directly so they can help faster.
What about falls? +
The Guardian includes automatic fall alert. If a hard fall is detected, it can notify your family contacts — so help can come even if your parent can't press the button.
Is it hard to set up? +
Not at all. Each Guardian ships pre-configured with your family's phone numbers. Just charge it, slip it on, and it's ready in minutes. No apps to install, no contracts to sign.
Is it water-resistant? +
Yes. The Guardian is water-resistant for everyday wear, including washing hands and showering, so it can stay on all day.
How long does the battery last? +
The Guardian is designed for multi-day battery life, so there's less daily charging to remember.
What's your return policy? +
Every order is covered by our 30-day money-back Peace of Mind Guarantee and a 1-year warranty. If it isn't right for your family, send it back for a full refund.
Do you ship for free? +
Yes — free express shipping on every order, with delivery typically in just a few business days.
