ReceptionRating · Positive reviews · Number of ratings

Watch Sensor Logger holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Physics Toolbox Sensor Suite has 1.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 81% of Physics Toolbox Sensor Suite's written reviews are positive against 50% of Watch Sensor Logger's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Physics Toolbox Sensor Suite ships an update weekly, Watch Sensor Logger every 25 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
