When you're staying in hotels, rental apartments, or guest rooms, you don't always know what might be connected around you. This app gives you peace of mind with fast, effective tools to help you understand your wireless environment β€” and stay in control. Temporary spaces shouldn't mean temporary security. Start by scanning for nearby Wi-Fi and Bluetooth activity. One tap reveals which devices are connected to the space around you, helping you spot anything that seems out of place. Whether it's unfamiliar connections or signals from nearby rooms, awareness is key. Infrared mode turns into a simple visual scanner. Bright white spots on the screen may indicate electronic components, even if they’re concealed. This feature is especially helpful when inspecting unfamiliar rooms for hidden electronics or unexpected sources of transmission. All scans are saved in an organized history so you can revisit and compare sessions easily. Whether you’re returning to the same place or noticing changes from one day to the next, your scan data helps build awareness over time. In-app guidance offers practical advice on where and how to scan more effectively β€” including high-risk zones like power outlets, shelves, vents, and TVs. You don’t need to be an expert to protect your digital space. Enjoy extra benefits: β€” Unlimited scans via Bluetooth and Wi-Fi; β€” Full infrared access for visual detection; β€” IP tracking with detailed connection info; β€” No ads, just clean, smooth performance.

EMF Detector

Features
Read full description

EMF Detector turns your iPhone's magnetometer into a live magnetic-field instrument, presented as a classic CRT vectorscope. The sensor is sampled at 100 Hz and monitored on two channels at once: steady field shifts from magnets, ferrous objects and motors, and AC ripple from live wiring. Field deviation is drawn as a phosphor beam with a persistence trail, and detected anomalies are marked on the scope and logged automatically with time and strength. VECTORSCOPE β€” the beam shows the direction and strength of the current disturbance; repeated activity builds a slowly fading heat picture of where it concentrates. ELITE 3D SCANNER β€” an alternative display in the style of the 1984 classic, showing the field's vertical component on a tilted scanner plane. BENCH-METER READOUTS β€” fourteen-segment displays for field strength, baseline, deviation and AC ripple, with a FIXED/AUTO baseline lock and one-tap re-baseline. APPLE WATCH β€” a companion app with its own sensor, alerts and a mini scope. PRO (one-time purchase): β€’ REM-POD MODE β€” park the phone at a location and monitor it from your wrist: the watch mirrors the scope, meter and anomalies live, with an optional alarm on the parked phone. β€’ WATCH REFERENCE MODE β€” use the watch as an ambient reference to distinguish local disturbances from room-wide changes. β€’ Map of geotagged anomalies, CSV/GPX export, unlimited history and custom sensitivity. The instrument measures real magnetic fields: readings reflect physical sources such as wiring, appliances and magnetised objects. How you use it is up to you.
