# StepNova vs Zafit AI

The clearest difference is update cadence: Zafit AI at every 2 days against StepNova's every 5 days. Zafit AI also leads on iOS requirement (15.1 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. StepNova sells 6 in-app purchases, starting at $1.99 per month and Zafit AI sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

StepNova ships an update every 5 days, Zafit AI every 2 days. The most recent releases landed on October 10, 2026 and October 8, 2026 respectively.
