Radiation is invisible.
Radspotter makes it visible.
We build connected instruments that turn invisible hazards into something you can see, measure, and act on. Radspotter, our smart Geiger counter, is the first.
Why we exist
Radiation detection
shouldn't feel like lab work.
Most radiation detectors are standalone boxes with a tiny screen and a number that only makes sense to an expert. You can read a value, but you can't easily see where the radiation is coming from — or make sense of it later.
We took a different approach. Keep the device thin, rugged, and affordable, and let the phone in your pocket do the heavy lifting — the display, the 3D map, the history, and the alerts. The result is Radspotter: point it, walk around, and watch radiation take shape on your screen.
Simple where it should be simple, honest where it counts. That's the standard we hold ourselves to on every product we build.
Real-time monitoring. Always on.

What drives us
Built on principles, not trends.
Honest Readings
A Geiger–Müller tube counts every particle it sees, and we stream the raw counts to your phone — no smoothed-over black-box number. We test every unit before it ships.
Design That Disappears
Safety tech shouldn't look like lab equipment. Our devices are designed to blend into your home, not stick out.
Instant Clarity
No waiting days for lab results. Real-time readings delivered to your phone with clear, actionable guidance.

How we got here.
The Idea
Jovian Scientific starts with a simple goal — make invisible radiation something anyone can see, measure, and locate, using the phone already in their pocket.
Radspotter
Our smart Geiger counter reaches its final hardware design: a thin, screen-free device that pairs with your phone over Bluetooth and maps radiation in 3D.
Radspotter Launch
Radspotter is available to reserve. Be among the first to hold radiation up to the light.
Radonix
Radonix, our WiFi-connected smart radon detector for the home, is in development — continuous monitoring, alerts, and a cloud dashboard.
