Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Arsenal 2 holds the better App Store score, 4.4 against 3.6. That said, the two scores are not equally well evidenced: Arsenal 2 has 942 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 29% of Arsenal 2's written reviews are positive against 33% of Caira's, so the app with the better star average is not the one people write more warmly about.
Arsenal 2 ships an update monthly, Caira every 3 weeks. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
