How It Works

Simple. Silent. Powerful.

01
Install & Forget
Download the app, grant Bluetooth and location permissions once. That's it. You never need to open it again.
02
Silent Scanning
BLEACORN quietly scans for BLE signals from Bluetooth-enabled medical devices, primarily pacemakers and neurostimulators, belonging to missing persons.
03
Signal Detected
If your phone passes within range of a target signal, BLEACORN captures the GPS coordinates and reports silently to authorities.
04
Someone Comes Home
Law enforcement sees the detection on a live map. Every person with the app is a node in a humanity network, covering ground no helicopter can.

Rewards

What Happens When You Help.

You won't even know it happened. If your phone detects a signal, it silently reports the location to authorities. You go about your day. If your detection leads to bringing someone home, the posted reward may be shared with you. Just register your device in the app with your name and phone so we can reach you.



BLEACORN does not determine or guarantee rewards. Eligibility is decided by the reward poster and applicable law.

Our Mission

"While helicopters search one spot,
millions of phones can search everywhere."

BLEACORN was inspired by watching search efforts for missing persons rely on expensive, limited resources -- while millions of Bluetooth-enabled smartphones sat idle in people's pockets.

Modern pacemakers and neurostimulators emit Bluetooth Low Energy signals every few minutes, around the clock, for the lifetime of the device (typically 10 to 15 years). BLEACORN turns every phone into a passive detector for those signals, building a crowd-sourced search network that grows with every install.

This is a public safety initiative. There are no ads, no subscriptions, no data sold. BLEACORN exists for one reason: to help families find their loved ones.
