Lumen · Personal anti-tracking
Lumen is a pocket-sized scanner that detects AirTags, Tiles, and other Bluetooth trackers nearby — even ones in silent mode. No phone required.
A quieter kind of safety
Apple's built-in alerts only fire after hours — sometimes days. Lumen scans continuously, catches what your phone misses, and tells you immediately, in plain language.
A single button starts a 360° scan of Bluetooth LE trackers within ~30 feet. Lumen filters out your own devices automatically.
A warm ring pulses when something unfamiliar is following you. It gets brighter as you get closer — like a dowsing rod, but for trackers.
Walk, tap twice to log the event with timestamp, or connect to your phone for serial details. Lumen never uploads anything.

AirTag · 18 ft · first seen 22 minutes ago near Kent Ave.
From early owners
"My ex put an AirTag in my toddler's backpack. Lumen caught it in the car pickup line. It's not a fun story, but I'm glad I had it."
"Honestly expected a gimmick. It caught a tracker in a used coat I'd thrifted within 24 hours of arriving."
"I travel for work and keep it clipped to my laptop bag. Quiet peace of mind — I forget it's there until I remember I own it."
