# Math AI vs QR Code Studio

The clearest difference is ads: QR Code Studio at none against Math AI's shown. QR Code Studio also leads on update cadence (every 4 days vs every 3 weeks) and iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Math AI sells 4 in-app purchases, starting at $0.99 per 7 days and QR Code Studio sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Math AI ships an update every 3 weeks, QR Code Studio every 4 days. The most recent releases landed on October 5, 2026 and September 8, 2026 respectively.
