# Calculator Pro vs QR Code

The clearest difference is rating: QR Code at 5.0 against Calculator Pro's 4.4. QR Code also leads on update cadence (every 4 days vs every 2 weeks) and device support (3 vs 1). Calculator Pro's advantage is ratings volume (62 vs 9). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calculator Pro sells 2 in-app purchases, starting at $4.99 per 7 days and QR Code sells 5 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

QR Code holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Calculator Pro has 62 ratings behind it against 9, so its average is the more settled of the two.

Calculator Pro ships an update every 2 weeks, QR Code every 4 days. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
