MAG-RAY Magnetic Monitor

Are you aware of the invisible magnetic fields surrounding you every day?

MAG-RAY turns your smartphone into a precision magnetic field meter — helping you understand and monitor the electromagnetic environment in your home, workplace, and daily life.

WHY MAGNETIC FIELD AWARENESS MATTERS
The World Health Organisation (WHO) and the International Agency for Research on Cancer (IARC) have classified extremely low frequency (ELF) magnetic fields as Group 2B — "possibly carcinogenic to humans." The International Commission on Non-Ionizing Radiation Protection (ICNIRP) publishes exposure reference levels and recommends awareness of prolonged exposure, particularly for children. While science continues to study the long-term effects, many health-conscious individuals and wellness practitioners choose to monitor and minimise unnecessary exposure as a precautionary measure.

WHAT MAG-RAY DOES
• Displays the live magnetic field intensity in microtesla (µT) — updated every second
• Visual green/red ring instantly shows whether you are near or above your personal threshold
• Set a custom alert threshold — the ICNIRP reference level for the general public is 200 µT at 50 Hz
• Day, Week and Month history charts reveal patterns in your exposure over time
• Min and Max reference lines show peak and baseline levels per period
• Background recording keeps a continuous log even with the screen off
• Share readings and charts with your health practitioner or wellness community
• Available in 12 languages

Use MAG-RAY near power lines, household appliances, electric meters, Wi-Fi routers, and any other source you wish to evaluate. Knowledge is the foundation of informed choices about your environment.
