# Algebra vs Sifaks

The clearest difference is iOS requirement: Algebra at 12.0 against Sifaks's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Algebra sells 1 one-off in-app purchase and Sifaks sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
