# Pre vs Algebra Flow

The clearest difference is in-app purchases: Algebra Flow at none against Pre's 1. Algebra Flow also leads on review sentiment (100% vs 67%) and rating (5.0 vs 4.7). Pre's advantage is ratings volume (357 vs 19) and iOS requirement (13.0 vs 15.1). On price, ads and device support there is nothing between them.

Both are free to download. Pre sells 1 in-app purchase, starting at $9.99 per month. Algebra Flow asks for nothing beyond the download.

Algebra Flow holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Pre has 357 ratings behind it against 19, so its average is the more settled of the two. Written reviews point the same way: 67% of Pre's written reviews are positive against 100% of Algebra Flow's.
