The RF Tools App from HUBER+SUHNER AG is a useful tool, which shows the relation between RF specific values like impedance, wave length, return loss (VSWR) and signal delay including their conversion. On top of this, the RF Assembly Calculator provides an easy comparison of H+S RF cables and assemblies in different configurations and in different environments. It offers a straight access to technical specifications such as insertion loss and power rating. Above all, engineers and students will love this handy and helpful tool. Content Tools Reflection measurement (Return loss - VSWR) Frequency wavelength (Wavelength calculation) Signal delay (Signal delay - Dielectric constant - Velocity in % of speed of light) Impedance dimension (calculation of impedance of coaxial line) dB Calculator (dB Ratio / Watt - dBm) RF Assembly Calculator (comparison of up to three HUBER+SUHNER RF cables) Used formulas are explained in detail by meaningful pictures. Products Provides an overview of HUBER+SUHNER products such as cables, connectors, antennas, lightning protectors and passive components with the help of the product catalogues.

Turn your iPhone into a powerful EMF detector and magnetic field scanner. Detect electromagnetic fields (EMF) around you instantly using the built-in sensor already inside your device — no expensive equipment required. Whether you want to monitor electromagnetic radiation in your home, locate hidden magnetic sources, or even explore paranormal activity, this app gives you a simple and exciting way to measure the invisible world around you. Use the app to scan bedrooms, walls, electrical appliances, Wi-Fi zones, sockets, microwaves, wireless devices, and more. Discover areas with unusually high magnetic activity and receive an instant warning beep when strong EMF levels are detected. Many users also enjoy using the app during ghost hunts and paranormal investigations, as sudden magnetic fluctuations are often associated with supernatural activity. NEW: Experience EMF detection in Augmented Reality. Visualize electromagnetic fields in Augmented Reality to better understand how EMFs spread throughout your home, office, or workspace. The app allows you to see a figurative representation of magnetic activity around you, helping you identify high-radiation zones and understand how far electromagnetic fields may reach in real-world environments. Explore EMFs in a more immersive and intuitive way by combining real-time detection with AR visualization technology. Transform your iPhone into a digital EMF Meter, Teslameter, or electromagnetic field tester using the internal compass hardware. View live magnetic field readings in real time and monitor changes on all three axes (X, Y, Z). Scientists, engineers, students, teachers, paranormal investigators, and curious explorers use EMF detectors to measure magnetic activity in everyday environments. Why use this app? • Detect high electromagnetic field zones around you • Monitor EMF levels near beds, appliances, or workspaces • Receive warning alerts when strong magnetic radiation is detected • Track and store measurements with time and date stamps • Investigate unusual magnetic fluctuations during ghost hunting sessions • Find metallic objects, pipes, or hidden sources behind walls • Explore the invisible electromagnetic world around you Features: • Real-time EMF and magnetic field detection • Warning beep near strong radiation sources • Measures magnetic force on X, Y, and Z axes • Magnetic readings displayed in microteslas (µT) • Save up to 100 EMF records • Record events with exact date & time • Export and send measurements by email • Easy-to-use digital display interface Electromagnetic radiation may come from electrical wiring, appliances, wireless devices, cordless phones, Wi-Fi equipment, sockets, and other electronic sources in your environment. Tips: For best accuracy, calibrate your iPhone by moving it in a figure-8 motion before use. Important: This app requires an iPhone with compass hardware and will not work on iPod Touch devices. Disclaimer: This app is intended for entertainment and informational purposes only. It uses the iPhone magnetometer sensor to detect magnetic field variations near ferromagnetic objects and electromagnetic sources. Download now and start discovering the hidden electromagnetic activity around you.

Verdict
The clearest difference is price: RF Tools at Free against EMF Field Detector RF Scanner's $4.99. RF Tools also leads on in-app purchases (none vs 2) and ads (none vs shown). EMF Field Detector RF Scanner's advantage is rating (4.5 vs 3.0) and update cadence (every 3 weeks vs every 14 months). On device support and iOS requirement there is nothing between them.
