# Num Trainer vs AI Guide

The clearest difference is ads: Num Trainer at none against AI Guide's shown. AI Guide's advantage is update cadence (daily vs every 9 days) and iOS requirement (13.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

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

Num Trainer ships an update every 9 days, AI Guide daily. The most recent releases landed on October 29, 2026 and October 25, 2026 respectively.
