# Zafit AI vs Stepwise

The clearest difference is ads: Zafit AI at none against Stepwise's shown. Zafit AI also leads on update cadence (every 2 days vs every 3 weeks) and device support (4 vs 1). On price and in-app purchases there is nothing between them.

Both are free to download. Zafit AI sells 4 in-app purchases, starting at $9.99 per month and Stepwise sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Zafit AI ships an update every 2 days, Stepwise every 3 weeks. Both last shipped on October 31, 2026.
