# Geometry!! vs Parametric Factorization

The clearest difference is rating: Geometry!! at 4.5 against Parametric Factorization's 2.9. Geometry!! also leads on review sentiment (67% vs 40%) and ratings volume (56 vs 8). Parametric Factorization's advantage is ads (none vs shown) and update cadence (fortnightly vs every 7 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Geometry!! sells 2 in-app purchases, starting at $0.99 per year and Parametric Factorization sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Geometry!! holds the better App Store score, 4.5 against 2.9. That said, the two scores are not equally well evidenced: Geometry!! has 56 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 67% of Geometry!!'s written reviews are positive against 40% of Parametric Factorization's.

Geometry!! ships an update every 7 months, Parametric Factorization fortnightly. The most recent releases landed on September 28, 2026 and October 2, 2026 respectively.
