KC761 Mapper vs RAYSID

KC761 Mapper is a field companion app for KC761 series radiation meters. Connect your device via Bluetooth, collect real-time measurements, and map radiation data directly onto your route. Use KC761 Mapper to monitor CPS and dose rate while moving, identify high/low zones quickly, and keep a clear history of survey sessions for later review. Key features: Bluetooth connection to KC761 devices Real-time CPS and dose rate display (uSv/h) GPS track mapping with color-coded measurement points Session history with show/hide and delete controls CSV export for analysis and reporting Local-only storage (no cloud sync) Built for practical field use: Works with KC761 capabilities (Gamma / Neutron / PIN as supported by device) Designed for fast scanning, clear visualization, and easy data export Privacy: Data is stored on-device No mandatory cloud account Disclaimer: KC761 Mapper is intended for use with KC761-compatible hardware. Measurements are for reference and should be interpreted by trained personnel where required.

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.
