A logger App that can measure acceleration, gyroscope, and magnetic field synchronously, then export as a CSV file. The measured values can be visualized in real-time by enabling "Realtime visualization". On the other hand, when you want to measure at a more accurate frequency, disabling "Realtime visualization" is preferred. Also, if the sampling rate is set too high, the same value may be sampled many times depending on the hardware specifications.

Verdict
The clearest difference is rating: QR code at 5.0 against SensorLogger's 4.5. QR code also leads on update cadence (every 6 days vs every 3 weeks) and chart position (#190 vs unranked). SensorLogger's advantage is ratings volume (11 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
