Radspotter · Now taking pre-orders
Radspotter is a pocket-sized Geiger counter that pairs with your phone to map radiation in 3D — so you can see where levels rise and track them straight to the source.
Nothing to set up · Pairs with your phone · Recharges over USB-C
Find the source
Hold Radspotter alongside your phone and walk the space. The app overlays live readings on your camera and builds a 3D map of the radiation around you — so you can watch levels climb and track them straight to the source.
Instant Alerts
When radiation climbs above background, Radspotter alerts you right away — the device flashes, and your phone sounds, vibrates, and pushes a notification, even if the app is closed.
