# COMath vs AMC

The clearest difference is ads: AMC at none against COMath's shown. AMC also leads on update cadence (weekly vs monthly) and monetization model (free vs ad-supported). COMath's advantage is ratings volume (45 vs 8). On price, rating, review sentiment and in-app purchases there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.8 for COMath against 4.8 for AMC. That said, the two scores are not equally well evidenced: COMath has 45 ratings behind it against 8, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

COMath ships an update monthly, AMC weekly. The most recent releases landed on September 21, 2026 and September 8, 2026 respectively.
