Spy Detector vs GroundLoop

SPY Detector – Extra Privacy & Safety Tools This app provides utility tools to help you check your surroundings and stay more aware of potential privacy risks. It is designed as a supportive tool only and should not be considered a guaranteed or professional security solution. Whether you are checking into a hotel, settling into an Airbnb, working from a co-working space or simply curious about the unseen signals around you, Spy Detector turns your iPhone's built-in sensors into a quick environmental scanner you can run in seconds — no extra hardware, no setup, no learning curve. Key Features: Light & Lens Check – Use your phone's camera and flash to look for unusual reflections, glints or lights that stand out in your environment. Signal & IR Modes – Visualize infrared light sources with the front camera and scan for irregular signals in the area around you. WiFi / Network Scanner – Review every device sharing your current WiFi network, including IP address, MAC vendor and hostname, so you can spot any connection you don't recognize. Bluetooth & BLE Scanner – Sweep nearby Bluetooth Low Energy broadcasts and see signal strength, identifiers and approximate distance of each transmitter. Remote Access Check – See which unknown devices may be reachable on the network you are connected to. Suspicious Device Alerts – Identify and highlight devices you may want to investigate further with a clean, sortable list. Magnetic Sensor Mode – Read live magnetometer values as you move your phone over walls, vents, smoke alarms, chargers and electronics. Spikes can indicate concentrated metal or active electronics inside an object. Simple & Quick – One-tap scanning with no complex setup, no jargon and no external tools required. Perfect For: Hotels & rentals (Airbnb, vacation homes, short-term stays) Public WiFi spots (cafes, airports, co-working spaces) Offices & shared spaces Renters inspecting a new apartment Personal awareness and peace of mind Why Spy Detector: - Runs entirely on your device, nothing is uploaded - No external hardware needed, just your iPhone - Clean, jargon-free interface designed for non-technical users - Optimized for iPhone and light on battery - Works fully offline once installed - Built around the sensors and radios your phone already has Important: Spy Detector is an awareness and inspection utility. It reports what your phone's sensors can measure — WiFi devices, Bluetooth broadcasts, magnetic field strength and visible infrared light. Results depend on your environment and your device's hardware, and the app does not guarantee detection of any specific object or device. It is not a substitute for professional security services. #This app may require additional purchases to access certain content or features.

GroundLoop is the grounding field companion for electrical engineers, contractors, and tower techs — fully offline, no account, no subscription. SOIL RESISTIVITY Enter Wenner four-pin or Schlumberger readings and get apparent resistivity per spacing instantly, with probe-depth correction, anomaly flags for layered soil, and a resistivity-vs-spacing curve you can read at the truck. ELECTRODE ESTIMATES Size a single rod, a multi-rod array, or a grid (Sverak screening formula) and compare against your target — 25 ohms (NEC 250.53), 5 ohms, or a custom spec. Every result shows the formula reference it came from. FALL-OF-POTENTIAL TESTS Enter your current-probe distance and GroundLoop lays out the 52/62/72% voltage-probe positions, then checks your three readings for a valid plateau — so a bad test gets caught in the field, not back at the office. FIELD REPORTS Export a clean PDF per site: resistivity tables, electrode estimates with formula references, fall-of-potential records, and date — ready for your project file. FREE TO TRY One site with every tool unlocked, reports watermarked. One-time purchase removes the watermark and the site limit. No subscription, ever. GroundLoop is a field calculation and recording aid. It encodes textbook formulas with cited references (values pending professional-engineer review are labeled in-app); it is not a substitute for a licensed PE's design, the governing standard, or required field verification.
