# Carnets vs Algorithms

The clearest difference is in-app purchases: Carnets at none against Algorithms's 3. Carnets also leads on ratings volume (316 vs 2) and chart position (#100 vs unranked). Algorithms's advantage is rating (5.0 vs 4.6) and review sentiment (100% vs 78%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Algorithms sells 3 one-off in-app purchases. Carnets asks for nothing beyond the download.

Algorithms holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Carnets has 316 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 78% of Carnets's written reviews are positive against 100% of Algorithms's.

Carnets ships an update monthly, Algorithms weekly. The most recent releases landed on October 13, 2026 and September 27, 2026 respectively.
