# Symbols vs Liminal

The clearest difference is rating: Liminal at 5.0 against Symbols's 4.6. Symbols's advantage is ratings volume (10 vs 2) and iOS requirement (12.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Symbols sells 6 in-app purchases, starting at $3.99 per month 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 4.6. That said, the two scores are not equally well evidenced: Symbols has 10 ratings behind it against 2, so its average is the more settled of the two.

Symbols ships an update every 6 weeks, Liminal every 3 weeks. The most recent releases landed on November 3, 2026 and November 2, 2026 respectively.
