# ODE vs Polynomial Regression

The clearest difference is ads: Polynomial Regression at none against ODE's shown. On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ODE ships an update every 5 weeks, Polynomial Regression every 3 weeks. The most recent releases landed on September 18, 2026 and December 14, 2025 respectively.
