Physics Toolbox Accelerometer vs DU CrimsonConnect
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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.
- 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.

Verdict
The clearest difference is rating: DU CrimsonConnect at 4.1 against Physics Toolbox Accelerometer's 2.0. DU CrimsonConnect also leads on update cadence (every 4 weeks vs every 8 months) and ratings volume (118 vs 5). Physics Toolbox Accelerometer's advantage is review sentiment (38% vs 25%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
DU CrimsonConnect holds the better App Store score, 4.1 against 2.0. That said, the two scores are not equally well evidenced: DU CrimsonConnect has 118 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 38% of Physics Toolbox Accelerometer's written reviews are positive against 25% of DU CrimsonConnect's, so the app with the better star average is not the one people write more warmly about.
Physics Toolbox Accelerometer ships an update every 8 months, DU CrimsonConnect every 4 weeks. The most recent releases landed on September 23, 2026 and October 5, 2026 respectively.
