# Mathrax vs Slicey

The clearest difference is rating: Mathrax at 5.0 against Slicey's 4.6. Slicey's advantage is ratings volume (14 vs 1) and iOS requirement (13.0 vs 17.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Mathrax sells 1 one-off in-app purchase and Slicey sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Mathrax holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Slicey has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Mathrax ships an update every 6 months, Slicey every 3 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
