# Roll Calculator vs QR Code

The clearest difference is in-app purchases: Roll Calculator at none against QR Code's 7. Roll Calculator also leads on iOS requirement (12.0 vs 14.0). QR Code's advantage is review sentiment (33% vs 0%) and ratings volume (13K vs 11). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. QR Code sells 7 in-app purchases, starting at $2.99 per 7 days. Roll Calculator asks for nothing beyond the download.

QR Code holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: QR Code has 13K ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 0% of Roll Calculator's written reviews are positive against 33% of QR Code's.

Roll Calculator ships an update fortnightly, QR Code every 9 days. The most recent releases landed on September 28, 2026 and October 14, 2026 respectively.
