# Slopes vs ODE

The clearest difference is ads: Slopes at none against ODE's shown. ODE's advantage is update cadence (every 5 weeks vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

Slopes ships an update every 2 months, ODE every 5 weeks. The most recent releases landed on June 1, 2026 and September 18, 2026 respectively.
