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. Hardware You will need a beacon from Estimote, Gimbal, Radius Networks RadBeacon, Kontakt or from any other iBeacon manufacturer, in order to use this app.

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.
