The worry you carry quietly
You know everything about them. A stranger knows nothing.
You know their blood group, allergies, and medications. But if something happens on the road or at the gym, the stranger next to them doesn't know any of it.
And their phone, the one thing that could connect them to you, is locked, dead, or out of reach.
How it works
It clips to the keys they already carry.
The lessworry tag clips onto their keychain. It weighs nothing, needs no charging, and stays with them everywhere.
If they need help and can't reach you, anyone nearby simply taps or scans the QR code to see your number, their medical info, and blood group. No app needed on either side.
What the tag shares
What you know, anyone nearby can see too
One tap or scan shows a helper what they need and how to reach you.
Your Phone Number
One-tap call button. They can reach you in seconds.
Medical Information
Blood group, allergies, medications. The details that matter when they can't speak for themselves.
WhatsApp Location
When scanned, the helper's location is sent to you on WhatsApp instantly.
Home Address
If they can't communicate, the helper knows where home is.
"You say 'drive safe' every morning.
Imagine if those two words could actually reach them,
through anyone, anywhere, with one tap."
— The thought behind every 'drive safe'
