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.

Harmonic Wave Equation Calculator is a physics/math calculator used to find the displacement of a given point along the wave, the position of that point, the time point, wave velocity, wavelength, amplitude, or initial phase of the wave quickly and easily. Features: - Instant calculation. - Results are copyable to other apps. - Formulas are included as references. - Supports up to 16 decimal places. - Supports various units for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. A harmonic of such a wave is a wave with a frequency that is a positive integer multiple of the frequency of the original wave, known as the fundamental frequency. The original wave is also called the 1st harmonic; the following harmonics are known as higher harmonics. Formula: y = A * sin[(2π / λ) * (x - vt) + Φ] where: y - displacement of a given point along the wave x - position of that point (its distance from the source) t - time point v - wave velocity λ - wavelength A - amplitude Φ - initial phase of the wave Thank you for your support, and feel free to visit nitrio.com for more apps for your iOS devices.

Verdict
The clearest difference is rating: Harmonic Wave Equation Calc at 5.0 against EMF Field Detector RF Scanner's 4.5. Harmonic Wave Equation Calc also leads on in-app purchases (none vs 2) and ads (none vs shown). EMF Field Detector RF Scanner's advantage is update cadence (every 3 weeks vs every 31 months) and ratings volume (5.5K vs 1). On device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
EMF Field Detector RF Scanner costs $4.99 and Harmonic Wave Equation Calc $2.99 up front. EMF Field Detector RF Scanner sells 2 one-off in-app purchases. Harmonic Wave Equation Calc asks for nothing beyond the download.
Harmonic Wave Equation Calc holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: EMF Field Detector RF Scanner has 5.5K ratings behind it against 1, so its average is the more settled of the two.
EMF Field Detector RF Scanner ships an update every 3 weeks, Harmonic Wave Equation Calc every 31 months. The most recent releases landed on November 12, 2026 and November 2, 2026 respectively.
