# Calculus 1 vs Dogl Calculus

The clearest difference is rating: Dogl Calculus at 4.8 against Calculus 1's 4.2. Dogl Calculus also leads on ratings volume (151 vs 21). Calculus 1's advantage is in-app purchases (none vs 3) and update cadence (every 10 days vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. Dogl Calculus sells 3 one-off in-app purchases. Calculus 1 asks for nothing beyond the download.

Dogl Calculus holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Dogl Calculus has 151 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 85% of Calculus 1'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.

Calculus 1 ships an update every 10 days, Dogl Calculus every 2 months. The most recent releases landed on October 14, 2026 and October 20, 2026 respectively.
