# DP vs AI

The clearest difference is in-app purchases: DP at none against AI's 1. DP also leads on iOS requirement (15.0 vs 17.0). AI's advantage is update cadence (weekly vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. AI sells 1 one-off in-app purchase. DP asks for nothing beyond the download.

DP ships an update every 2 months, AI weekly. The most recent releases landed on October 30, 2026 and October 29, 2026 respectively.
