## X-ref Description
X-ref is a fast, offline reference and calculator for X-ray physics, diffraction, and spectroscopy. It's built for beamline scientists and lab work. Quickly look up conversions and values so it shouldn't slow down an experiment.

Buy it once and carry it to any synchrotron. No subscription, no accounts, no ads.

WHAT IT DOES
- Element X-ray data,  periodic table for X-ray work, with emission and absorption lines
- Energy and wavelength conversion
- Attenuation estimation, X-ray attenuation through materials to plan filters, windows, and samples

WORKS WHERE YOU WORK
X-ref runs entirely on your device. No login, no network, no cloud. It works on an airplane, in the field, and inside a lead-lined experimental hutch with no connectivity.

WHO IT'S FOR
Beamline scientists and facility staff, visiting researchers, crystallographers, structural biologists, materials scientists, XRD/XRF practitioners, and students learning X-ray methods.

PRIVACY BY DESIGN
X-ref collects no data, no analytics, no tracking, no crash reporting, no third-party code. Nothing is gathered.

X-ref is a scientific reference tool. It does not capture medical images, diagnose conditions, provide treatment guidance, or measure radiation using device hardware.
