Physics Toolbox Accelerometer vs Unrulr
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.
Unrulr
This app allows users to capture evidence of learning through images, videos, and documents. Users can construct posts around learning goals and share them in a private community for reflection, discussion, and assessment. It helps build a portfolio of skills backed by authentic evidence.
- Capture learning evidence (images, video, documents)
- Construct posts around learning goals

Verdict
The clearest difference is rating: Unrulr at 3.1 against Physics Toolbox Accelerometer's 2.0. Unrulr also leads on in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 8 months). On price, ads, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Physics Toolbox Accelerometer sells 1 one-off in-app purchase. Unrulr asks for nothing beyond the download.
Unrulr holds the better App Store score, 3.1 against 2.0. That said, the two scores are not equally well evidenced: Unrulr has 61 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 38% of Physics Toolbox Accelerometer's written reviews are positive against 48% of Unrulr's.
Physics Toolbox Accelerometer ships an update every 8 months, Unrulr every 3 weeks. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
