# Ninefall vs Adversary

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

Both are free to download. Ninefall sells 1 one-off in-app purchase and Adversary sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Ninefall ships an update every 2 weeks, Adversary every 2 days. The most recent releases landed on October 28, 2026 and October 31, 2026 respectively.
