# Sensor Logger vs QR Code Scanner＊Barcode Reader

The clearest difference is review sentiment: QR Code Scanner＊Barcode Reader at 97% against Sensor Logger's 44%. Sensor Logger's advantage is rating (4.8 vs 4.3). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Sensor Logger sells 6 in-app purchases, starting at $4.99 per month and QR Code Scanner＊Barcode Reader sells 12 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Sensor Logger holds the better App Store score, 4.8 against 4.3. Both are backed by a comparable volume of ratings — 111 and 84 respectively. Written reviews complicate that: 44% of Sensor Logger's written reviews are positive against 97% of QR Code Scanner＊Barcode Reader's, so the app with the better star average is not the one people write more warmly about.
