# QR Code Scanner vs Memory Master

The clearest difference is rating: Memory Master at 3.5 against QR Code Scanner's 3.0. Memory Master also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 24 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. QR Code Scanner sells 3 in-app purchases, starting at $7.99 per 7 days and Memory Master sells 7 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Memory Master holds the better App Store score, 3.5 against 3.0. That said, the two scores are not equally well evidenced: Memory Master has 20 ratings behind it against 1, so its average is the more settled of the two.

QR Code Scanner ships an update every 24 months, Memory Master every 3 weeks. Both last shipped on October 12, 2026.
