# Ellipse vs Gravity Physics

The clearest difference is in-app purchases: Gravity Physics at none against Ellipse's 3. Gravity Physics also leads on update cadence (weekly vs monthly). Ellipse's advantage is iOS requirement (15.0 vs 17.6). On price, ads and device support there is nothing between them.

Both are free to download. Ellipse sells 3 one-off in-app purchases. Gravity Physics asks for nothing beyond the download.

Ellipse ships an update monthly, Gravity Physics weekly. The most recent releases landed on October 14, 2026 and October 6, 2026 respectively.
