Know they're safe — the moment you wonder.
Send a ping to a trusted contact and get their exact location back — address, distance, even battery level — with one-tap Google Maps. It answers even on silent, even with no internet, even if they can't pick up. Buy it once, and it's there for life.
Peace of mind for the people you love
You don't need a reason to worry — you just do. Here's how one ping, or one alert, turns that worry back into calm.
Mum isn't answering
You've called twice. Was the phone on silent? Did something happen? Instead of imagining the worst, you send one ping.
She's at the market. Safe.First day across town
Your kid started a new job — or has a match the other side of the city. One quiet ping tells you they got there, without calling five times.
Arrived. No fuss.Coming home late
You'd rather not stay up refreshing your phone. Set a Departure Alert on their phone, from yours — a full-screen, loud alert fires the moment they leave.
You'll know they're on the way.Late and not picking up
Your partner should've been home by now. Before the worry spirals, one ping shows them moving — driving, en route, almost back.
En route. Worry gone.The 4am train stop
Travelling overnight and terrified of sleeping past your station? Set an Arrival Alert 40km out and actually sleep — it wakes you, loud, when your stop is near.
It wakes you in time.Drop-off at sports class
Badminton, coaching, practice. Arrival and departure alerts mean you always know they got there — and that they've safely left for home.
Arrived, and left. Both.The call you hope never comes
If your parents live alone, you already know the quiet fear. One fall in the kitchen, one bad moment — and no one knows for hours.
There are real, heartbreaking reports of seniors found a day later, simply because no one realised in time. It's the kind of thing you push out of your mind because it's too painful to sit with.
You can't be there every minute. But something can quietly keep watch — and shout for you the second something seems wrong.
A quiet watch over the people who raised you
Turn on Auto-Ping to keep getting their location at the interval you choose, and set an Activity Alert: if there's no movement on their phone for the hours you set, it fires an unmissable alert — so you can call, or go, in time.
One ping. Their exact location.
No dashboards, no constant tracking, no setup marathon. When you wonder, you ask — and you get a real answer.
Ask a trusted contact
Tap a person you've added. It works even if their phone's on silent, and even if they can't pick up — it answers automatically for contacts they've authorized.
Address, distance, battery
Back comes coordinates, the address, how far away they are, battery level and last activity — using GPS, cell and Wi-Fi for accuracy. Even with no internet, over SMS.
SOS
Open in Google Maps
One tap opens turn-by-turn directions in Google Maps. And if it's an emergency, one-tap SOS sounds loudly and bypasses silent mode.
A safety net shouldn't have a monthly bill
The whole point of a safety net is that it's always there. So why do most family-locator apps make you pay for it again every single month?
forever.
- The bill never stops, year after year.
- Miss a payment and it switches off.
- Maybe the very month you needed it most.
never again.
- Pay one time — it's yours for life.
- Nothing to renew, nothing to lapse.
- Still there, ready, two years from now.
We never know when we'll need it. With Kaizen Locator, the answer is always yes — even two years from now.

Works without them acting
It answers automatically for contacts they've authorized — even on silent, even if they don't pick up or do anything.
Works without internet

Auto-Ping
Set an interval and keep getting their location automatically — no need to ask each time.
Activity Alert
If there's no activity for the hours you set, it fires an alert — built for keeping an eye on elderly parents.
One-tap SOS + Auto-SOS
A loud SOS that bypasses silent mode, on demand or automatically — for the moments that can't wait.

Peace of mind, for life — for one payment.
