Physics Toolbox Accelerometer vs PocketLab Classic

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.

The PocketLab app brings together science curriculum, hands-on lessons, and data sensors for science learning. We built PocketLab for the curious explorers, educators, students, and makers to bring science, technology, engineering, and math (STEM) to life like never before. PocketLab sensors connect with a single button to your iPhone or iPad and instantly stream measurement data that you can see and record. PocketLab sensors are designed for investigating physics, biology, chemistry, Earth science, environmental science, and engineering. Using the PocketLab app, you can easily analyze your data, create graphs, and integrate your data with other software. PocketLab has the same features as lab equipment that costs thousands of dollars but is low cost and intuitive to use. NOTE: The PocketLab app is designed to pair with a PocketLab sensor.
