# QR vs MathAlarm

The clearest difference is price: QR at Free against MathAlarm's $0.99. QR also leads on ratings volume (1.1K vs 2) and iOS requirement (15.4 vs 26.0). MathAlarm's advantage is in-app purchases (none vs 3) and ads (none vs shown). On update cadence and device support there is nothing between them.

QR is free to download; MathAlarm costs $0.99 up front. QR sells 3 in-app purchases, starting at $9.99 per 7 days. MathAlarm asks for nothing beyond the download.

MathAlarm holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: QR has 1.1K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 69% of QR's written reviews are positive against 100% of MathAlarm's.

QR ships an update fortnightly, MathAlarm every 3 weeks. The most recent releases landed on November 3, 2026 and November 2, 2026 respectively.
