# PTCB vs Memory Rx

The clearest difference is rating: PTCB at 4.7 against Memory Rx's 1.0. PTCB also leads on ratings volume (557 vs 1) and update cadence (every 2 weeks vs every 5 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. PTCB sells 2 in-app purchases, starting at $24.99 per month and Memory Rx sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

PTCB holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: PTCB has 557 ratings behind it against 1, so its average is the more settled of the two.

PTCB ships an update every 2 weeks, Memory Rx every 5 weeks. The most recent releases landed on October 12, 2026 and October 7, 2026 respectively.
