Fault is a high-precision seismic activity visualiser that transforms your Android 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 colour-coded, giving you a clear and intuitive visualisation of motion patterns—whether you're measuring vehicle vibrations, structural resonance, or everyday movements.

Advanced Signal Processing

Traditional raw sensor data is noisy and difficult to interpret. Fault solves this with a robust filtering engine that applies:

High-pass filtering to eliminate gravity

Low-pass smoothing to clarify subtle motion

Dynamic gain scaling for enhanced sensitivity across devices

This results in clean, stable, and meaningful motion readings every time.

Instant Shake & Event Detection

Fault detects unusual activity in real time and highlights:

Peak acceleration

Event duration

Motion intensity

Whether it's a strong shake, an abrupt jolt, or a continuous vibration, you’ll see a clear breakdown of the event as it happens.

Customisable Experience

Tune Fault to suit your environment or research needs with adjustable settings:

Sensitivity and gain

Filter strength

Smoothing window

Axis visibility

Sampling rate

Frame rate

Every setting gives you deeper control over how motion is captured and displayed.

Elegant, Minimal Design

Fault features:

A clean, distraction-free interface

A simple menu for quick navigation

A static splash screen for fast launches

Smooth 60+ FPS visual rendering

The experience is lightweight, responsive, and crafted for both casual users and professionals.

Powered by a Modern Sensor Engine

Unlike typical seismograph apps, Fault uses a custom rendering pipeline built with SurfaceView and circular buffering, ensuring exceptional performance and accuracy—even during fast movements or prolonged monitoring sessions.
