# Equations vs Volume and Geometry

The clearest difference is in-app purchases: Equations at none against Volume and Geometry's 2. Volume and Geometry's advantage is update cadence (every 3 weeks vs every 2 months) and ratings volume (178 vs 14). On price, rating, ads and device support there is nothing between them.

Both are free to download. Volume and Geometry sells 2 one-off in-app purchases. Equations asks for nothing beyond the download.

Volume and Geometry holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Volume and Geometry has 178 ratings behind it against 14, so its average is the more settled of the two.

Equations ships an update every 2 months, Volume and Geometry every 3 weeks. The most recent releases landed on September 12, 2026 and August 6, 2026 respectively.
