# SensorLog vs Accelerometer

The clearest difference is price: Accelerometer at Free against SensorLog's $2.99. SensorLog's advantage is rating (4.4 vs 4.0) and ratings volume (40 vs 1). On ads, in-app purchases, monetization model and device support there is nothing between them.

Accelerometer is free to download; SensorLog costs $2.99 up front. SensorLog sells 4 one-off in-app purchases and Accelerometer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SensorLog holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: SensorLog has 40 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 69% of SensorLog's written reviews are positive against 54% of Accelerometer's.

SensorLog ships an update every 2 months, Accelerometer every 5 months. The most recent releases landed on September 21, 2026 and June 9, 2026 respectively.
