# Cracking the Cryptic vs AstroKnot

The clearest difference is update cadence: AstroKnot at every 3 days against Cracking the Cryptic's every 3 weeks. Cracking the Cryptic's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Cracking the Cryptic sells 13 one-off in-app purchases and AstroKnot sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Cracking the Cryptic ships an update every 3 weeks, AstroKnot every 3 days. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
