# Ujitsu vs Grappling AI

The clearest difference is ads: Ujitsu at none against Grappling AI's shown. Grappling AI's advantage is update cadence (every 2 days vs weekly) and iOS requirement (15.1 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Ujitsu sells 4 in-app purchases, starting at $9.99 per month and Grappling AI sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Ujitsu ships an update weekly, Grappling AI every 2 days. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
