Kashf Lens

Kashf Lens turns your iPhone into a multi-sensor exploration tool. Visualize real-time data from three built-in sensors - magnetometer, microphone, and camera - presented through a sleek, immersive interface. IMPORTANT: Kashf Lens reads raw sensor data from your iPhone's hardware. It is NOT a professional inspection device and does NOT reliably locate objects inside walls. Sensor readings are influenced by many environmental factors and should be treated as exploratory data, not definitive results. WHAT THE SENSORS MEASURE: MAGNETOMETER Reads magnetic field intensity in microteslas using your iPhone's built-in magnetometer. Displays real-time fluctuations as you move your device near surfaces. Magnetic field changes may be caused by nearby electronics, metal structures, Earth's field variations, or other environmental sources. Uses Kalman filtering for smoother readings. SOUND FREQUENCY ANALYZER Records audio from your iPhone's microphone when you tap a surface. Analyzes the frequency spectrum using FFT (Fast Fourier Transform) to compare sound characteristics. Different surface materials produce different acoustic responses. CAMERA SURFACE INSPECTOR Uses your iPhone's camera with image processing to highlight visual textures, edges, and surface patterns in real time. Applies saliency detection algorithms to identify areas of visual interest on surfaces. FEATURES: - Real-time sensor data visualization - Room-by-room session logging - Advanced haptic feedback (Core Haptics) - Dark, immersive interface optimized for OLED - 100% offline - no data leaves your device - Educational sensor exploration WHO USES KASHF LENS: - Curious minds exploring how phone sensors work - Students learning about magnetism and acoustics - DIY hobbyists experimenting with sensor readings - Paranormal enthusiasts and Ruqyah practitioners - Anyone interested in environmental sensor data Results vary based on device model, environmental conditions, and surface materials. Kashf Lens is an educational sensor exploration app. It does not replace professional tools or inspection equipment. Your data never leaves your device. Full privacy, always offline.

Verdict
The clearest difference is update cadence: Kashf Lens at weekly against GPS's every 4 months. GPS's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
