# SensorLogger vs QR code

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.

SensorLogger costs $0.99 and QR code $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

QR code holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: SensorLogger has 11 ratings behind it against 1, so its average is the more settled of the two.

SensorLogger ships an update every 3 weeks, QR code every 6 days. The most recent releases landed on September 29, 2026 and September 23, 2026 respectively.
