# Carnets vs Arrayground

The clearest difference is update cadence: Arrayground at every 5 days against Carnets's monthly. Arrayground also leads on review sentiment (100% vs 78%) and rating (4.8 vs 4.6). Carnets's advantage is ratings volume (316 vs 4) and chart position (#88 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Arrayground holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Carnets has 316 ratings behind it against 4, 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 Arrayground's.

Carnets ships an update monthly, Arrayground every 5 days. The most recent releases landed on September 24, 2026 and August 5, 2026 respectively.
