# Octal vs Polynomial Solver Step by Step

The clearest difference is in-app purchases: Polynomial Solver Step by Step at none against Octal's 1. Polynomial Solver Step by Step also leads on ads (none vs shown) and update cadence (every 4 days vs every 5 months). Octal's advantage is iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.

Both are free to download. Octal sells 1 one-off in-app purchase. Polynomial Solver Step by Step asks for nothing beyond the download.

Octal ships an update every 5 months, Polynomial Solver Step by Step every 4 days. The most recent releases landed on October 27, 2026 and October 30, 2026 respectively.
