# ClueKeeper vs Cracking the Cryptic

The clearest difference is in-app purchases: ClueKeeper at none against Cracking the Cryptic's 13. Cracking the Cryptic's advantage is update cadence (every 3 weeks vs every 3 months) and ratings volume (208 vs 20). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Cracking the Cryptic sells 13 one-off in-app purchases. ClueKeeper asks for nothing beyond the download.

ClueKeeper holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Cracking the Cryptic has 208 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 67% of ClueKeeper's written reviews are positive against 72% of Cracking the Cryptic's, so the app with the better star average is not the one people write more warmly about.

ClueKeeper ships an update every 3 months, Cracking the Cryptic every 3 weeks. The most recent releases landed on September 6, 2026 and September 21, 2026 respectively.
