Ring True vs Spy Camera Network Scanner

Strike a coin, hear the truth. Ring True estimates the silver content of ANY coin from the sound it makes — no per-coin database required. Real physics, not guesswork: a coin rings at frequencies set by its size and its metal's stiffness. Silver rings lower and dramatically longer than copper-nickel. Enter the coin's diameter and weight (or pick a preset - Morgans, pre-1965 US coinage, Silver Eagles, Maples, world crowns), balance it on a fingertip, tap its edge, and the app captures and analyzes the ring automatically. • Silver percentage estimate from the ring tone • Gold mode for gold–copper coins like Gold Eagles and Krugerrands • Independent density cross-check flags clad, plated, and filled fakes • Ring sustain (Q) analysis - genuine silver rings for seconds • Automatic rejection of knocks, taps, and background noise • Size-class mode for coins you don't have exact specs for • Bonus magnetometer mode: instantly catch ferrous (iron/steel) fakes Everything runs on your phone. No account, no ads. Nothing is sent anywhere unless you choose to send feedback on a result. Results are estimates for hobby use, not a professional assay.

Feel more confident in hotels, Airbnbs, vacation rentals, and unfamiliar spaces. Spy Camera Network Scanner helps you inspect your surroundings using the connectivity and sensors already built into your iPhone. Discover nearby devices, identify signals that may be associated with cameras, and investigate anything that looks worth checking. WI-FI & BLUETOOTH SCANNER Scan devices on your Wi-Fi network or nearby over Bluetooth. Instead of showing you technical data you have to interpret yourself, the app analyzes available device information to help identify recognized devices, unknown devices, and devices showing camera-related characteristics. If something is worth checking, you'll see why it was highlighted so you can investigate further. VISUAL CAMERA FILTERS Use live color filters to inspect objects, reflections, and bright points around you. Switch between different views for a closer look at areas that catch your attention. MAGNETIC FIELD SENSOR Use your iPhone's built-in magnetometer to observe changes in magnetic field strength around nearby objects and electronics. DESIGNED FOR PEACE OF MIND Whether you're checking into a hotel, staying in an Airbnb, or simply want to better understand the devices around you, Spy Camera Network Scanner gives you simple tools to inspect your surroundings in one place. IMPORTANT Spy Camera Network Scanner helps identify signals and device characteristics that may be associated with cameras or monitoring equipment. It does not confirm that a hidden camera is present or that a detected device is recording. A highlighted device means it may be worth checking further, not that a hidden camera has been detected. Likewise, no camera-related signals being identified does not guarantee that no hidden camera is present. Camera filters are visual inspection tools and do not provide thermal imaging. https://www.apple.com/legal/internet-services/itunes/dev/stdeula
