# Average.app vs 3D Geometry

The clearest difference is in-app purchases: Average.app at none against 3D Geometry's 1. 3D Geometry's advantage is ads (none vs shown) and update cadence (every 5 days vs every 4 weeks). On price, device support and iOS requirement there is nothing between them.

Both are free to download. 3D Geometry sells 1 one-off in-app purchase. Average.app asks for nothing beyond the download.

Average.app ships an update every 4 weeks, 3D Geometry every 5 days. Both last shipped on October 25, 2026.
