# Partial fraction decomposition vs Phyzix

The clearest difference is update cadence: Phyzix at every 2 days against Partial fraction decomposition's every 10 days. Partial fraction decomposition's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Partial fraction decomposition sells 1 one-off in-app purchase and Phyzix sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Partial fraction decomposition ships an update every 10 days, Phyzix every 2 days. The most recent releases landed on October 10, 2026 and October 1, 2026 respectively.
