# CoreMotion Data Recorder vs Accelerometer ∞

The clearest difference is review sentiment: CoreMotion Data Recorder at 100% against Accelerometer ∞'s 50%. CoreMotion Data Recorder also leads on ads (none vs shown) and device support (3 vs 1). Accelerometer ∞'s advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (65 vs 1). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. CoreMotion Data Recorder sells 1 one-off in-app purchase and Accelerometer ∞ sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Accelerometer ∞ holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Accelerometer ∞ has 65 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of CoreMotion Data Recorder's written reviews are positive against 50% of Accelerometer ∞'s, so the app with the better star average is not the one people write more warmly about.

CoreMotion Data Recorder ships an update every 2 months, Accelerometer ∞ every 2 weeks. The most recent releases landed on September 21, 2026 and October 11, 2026 respectively.
