# Carboline vs A.I.M.

The clearest difference is rating: Carboline at 4.8 against A.I.M.'s 3.7. Carboline also leads on ratings volume (21 vs 3). A.I.M.'s advantage is update cadence (fortnightly vs every 4 months) and iOS requirement (12.0 vs 15.1). 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.

Carboline holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Carboline has 21 ratings behind it against 3, so its average is the more settled of the two.

Carboline ships an update every 4 months, A.I.M. fortnightly. Both last shipped on June 5, 2026.
