About

Physics Toolbox Accelerometer

This app uses your device's accelerometer to measure and graph G-Force and acceleration over time. It allows you to record and export data as a CSV file, making it useful for analyzing motion in vehicles, vibrations, and educational physics experiments.

Highlights
  • Measures G-Force and acceleration
  • Graphs G-Force vs. Time
  • Graphs Acceleration vs. Time
  • Records and exports data as CSV
  • Analyzes motion in vehicles and vibrations
  • Useful for classroom physics experiments

Turn your iPhone into a motion laboratory. Physics Toolbox Accelerometer reads the accelerometer built into your device and shows exactly what it measures — live, in three dimensions, in units you can check. MEASURE • G-Force — the ratio of normal force to gravity, in X, Y, Z and total magnitude • Linear Acceleration — the same motion with gravity removed, in m/s² • Spectrum — a live FFT that finds the dominant frequency in a vibration RECORD AND ANALYSE • Record any run to CSV, then replay it with duration, maximum and average • Import CSV files recorded elsewhere and analyse them the same way • Share a recording straight from the app BUILT FOR TEACHING Each mode explains the physics behind it: how a piezoresistive cantilever bends under acceleration, how a capacitive accelerometer varies the electric potential across its plates, and why an object in free fall reads zero g. PRO A single lifetime purchase unlocks the signal filters — moving average, Kalman and low-pass — and analysis of saved and imported recordings. Works on iPhone and iPad, in light and dark, with VoiceOver throughout.
