# MemoryPie vs Liminal

The clearest difference is rating: Liminal at 5.0 against MemoryPie's 4.7. Liminal also leads on update cadence (every 3 weeks vs every 3 months). MemoryPie's advantage is ratings volume (80 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. MemoryPie sells 1 one-off in-app purchase and Liminal sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Liminal holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: MemoryPie has 80 ratings behind it against 2, so its average is the more settled of the two.

MemoryPie ships an update every 3 months, Liminal every 3 weeks. Both last shipped on November 2, 2026.
