# Geometry vs Acadi

The clearest difference is in-app purchases: Acadi at none against Geometry's 1. Acadi also leads on device support (3 vs 1). Geometry's advantage is update cadence (every 4 months vs every 12 months) and iOS requirement (4.3 vs 15.1). On price and ads there is nothing between them.

Both are free to download. Geometry sells 1 one-off in-app purchase. Acadi asks for nothing beyond the download.

Geometry ships an update every 4 months, Acadi every 12 months. The most recent releases landed on June 11, 2026 and September 20, 2026 respectively.
