# Sumaze! vs Dogl Calculus

The clearest difference is rating: Dogl Calculus at 4.8 against Sumaze!'s 3.8. Dogl Calculus also leads on ratings volume (151 vs 5). Sumaze!'s advantage is in-app purchases (none vs 3) and iOS requirement (6.0 vs 15.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Dogl Calculus sells 3 one-off in-app purchases. Sumaze! asks for nothing beyond the download.

Dogl Calculus holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Dogl Calculus has 151 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 83% of Sumaze!'s written reviews are positive against 75% of Dogl Calculus's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
