# Physics Toolbox Accelerometer vs Arduino Science Journal

The clearest difference is rating: Arduino Science Journal at 4.4 against Physics Toolbox Accelerometer's 2.0. Arduino Science Journal also leads on ratings volume (1.1K vs 5) and review sentiment (59% vs 38%). Physics Toolbox Accelerometer's advantage is in-app purchases (none vs 2). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Arduino Science Journal sells 2 in-app purchases, starting at $7.99 per month. Physics Toolbox Accelerometer asks for nothing beyond the download.

Arduino Science Journal holds the better App Store score, 4.4 against 2.0. That said, the two scores are not equally well evidenced: Arduino Science Journal has 1.1K 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 59% of Arduino Science Journal's.

Physics Toolbox Accelerometer ships an update every 8 months, Arduino Science Journal every 3 months. The most recent releases landed on October 9, 2026 and October 13, 2026 respectively.
