BeaconTrap scans for iBeacons in the background and triggers preset actions when the configured preconditions are met. Actions Trigger HTTP Requests and Notifications Enter/Exit Triggers Trigger actions wehen a beacon becomes close or when leaving a beacon's region. Trigger Preconditions Additionally to immediately triggering an action when an iBeacon signal is received, BeaconTrap allows the configuration of the following preconditions: - RSSI threshold You can set a minimum RSSI (signal strength) threshold value for triggering actions - Knock twice The beacon wakes up the app in the background which listens to knock gestures. Knock twice on your device to trigger the action. - Arrival/Departure only Prevents triggering an action when you are leaving a place where you have stayed some time (~10min). This works great for door buzzers, where you only want to open a door uppon arriving at a place. Export Configuration Export your trap configuration to other devices with a shareable link. Have a look at the website for an example configuration. Quick-Actions Swipe to arm/disarm a trap or manually trigger enter/exit actions.

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.
