# SensorLog vs CoreMotion Data Recorder

The clearest difference is price: CoreMotion Data Recorder at Free against SensorLog's $2.99. CoreMotion Data Recorder also leads on review sentiment (100% vs 69%) and iOS requirement (14.0 vs 18.0). SensorLog's advantage is rating (4.4 vs 4.0) and ratings volume (40 vs 1). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

CoreMotion Data Recorder is free to download; SensorLog costs $2.99 up front. SensorLog sells 4 one-off in-app purchases and CoreMotion Data Recorder 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 complicate that: 69% of SensorLog's written reviews are positive against 100% of CoreMotion Data Recorder's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 18, 2026 and September 21, 2026 respectively.
