Fault is a high-precision seismic activity visualiser that transforms your device into a real-time motion analysis tool. Built on advanced sensor filtering and a custom high-performance waveform engine, Fault helps you observe subtle tremors, vibrations, and shifts in your environment—instantly and with remarkable clarity. Designed for enthusiasts, students, researchers, engineers, and anyone curious about the motion around them, Fault brings professional-grade motion insight to your pocket without requiring any external hardware. Real-Time Seismograph Fault captures live acceleration data from your device’s built-in sensors and displays it as a dynamic 3-axis waveform. Each axis is uniquely color-coded, providing a clear and intuitive visualization of motion patterns—whether you're measuring vehicle vibrations, structural resonance, or everyday movement. Advanced Signal Processing Raw sensor data is often noisy and difficult to interpret. Fault applies intelligent filtering techniques including: High-pass filtering to reduce gravity influence Low-pass smoothing to clarify subtle motion Dynamic gain scaling for enhanced sensitivity The result is clean, stable, and meaningful motion readings. Instant Shake & Event Detection Fault detects unusual motion in real time and highlights: Peak acceleration Event duration Motion intensity From sudden jolts to continuous vibration, every event is clearly broken down as it happens. Customisable Experience Fine-tune how motion is captured and displayed with adjustable: Sensitivity and gain Filter strength Smoothing window Axis visibility Sampling rate Frame rate Every control gives you deeper precision. Elegant, Minimal Design Clean, distraction-free interface Simple menu for quick navigation Fast launch splash screen Smooth high-frame-rate rendering Lightweight, responsive, and crafted for both casual users and professionals. Powered by a Modern Sensor Engine Fault uses a custom rendering pipeline with circular buffering to ensure exceptional performance and accuracy—even during fast movements or long monitoring sessions. Who Is Fault For? Earth science students Structural engineers Vibration analysts Hardware testers DIY researchers Curious explorers From detecting table vibrations to monitoring building stability during strong winds, the possibilities are endlessly fascinating.

Verdict
The clearest difference is in-app purchases: Fault at none against Haptic Hit's 1. Fault also leads on device support. Haptic Hit's advantage is iOS requirement (15.1 vs 26.2). On price there is nothing between them.
