## Description

Now with a local radiation map - record geotagged readings and see them over an optional community layer. Plus sharper isotope peak detection.

Raysid is the iOS companion app for the RAYSID CsI(Tl) gamma spectrometer.

Connect to your RAYSID over Bluetooth and see radiation in real time:

• Live count rate (CPS) and dose rate (µSv/h)
• Accumulated dose and yearly projection
• 33-bin coarse histogram for quick scanning
• 1800-channel high-resolution spectrum with log or linear axis
• Automatic isotope identification against a built-in library of 43 reference spectra (natural, medical, and industrial isotopes)
• Device threshold alarms with phone notifications, sound, and haptic
• Phone-side Geiger clicks through the speaker, AirPods, or car audio
• Export the high-resolution spectrum as a standards-compliant N42 file
• Local radiation map: record your readings geotagged to where you took them, view them by count rate or dose, with an optional community layer. Recorded only while the app is open; your map stays on your device.

You'll need a RAYSID device to use this app. Your measurements, location, and recorded map stay on your phone - nothing is uploaded.

This app is an independent companion and is not affiliated with the RAYSID device manufacturer.
