# CarMeter vs QR Analyzer

The clearest difference is update cadence: QR Analyzer at every 3 weeks against CarMeter's every 7 months. QR Analyzer also leads on device support (3 vs 1) and iOS requirement (15.6 vs 17.6). On price, ads and in-app purchases there is nothing between them.

Both are free to download. CarMeter sells 1 in-app purchase, starting at $1.99 per month and QR Analyzer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CarMeter ships an update every 7 months, QR Analyzer every 3 weeks. The most recent releases landed on September 15, 2026 and July 2, 2026 respectively.
