# Geometry Stash vs ACT Math

The clearest difference is in-app purchases: Geometry Stash at none against ACT Math's 1. Geometry Stash also leads on update cadence (every 6 weeks vs every 11 months) and ratings volume (11 vs 1). ACT Math's advantage is rating (5.0 vs 4.7). On price, ads, monetization model and device support there is nothing between them.

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

ACT Math holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Geometry Stash has 11 ratings behind it against 1, so its average is the more settled of the two.

Geometry Stash ships an update every 6 weeks, ACT Math every 11 months. The most recent releases landed on October 15, 2026 and September 30, 2026 respectively.
