# AZ vs AI

The clearest difference is in-app purchases: AI at none against AZ's 4. AZ's advantage is update cadence (fortnightly vs every 3 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. AZ sells 4 in-app purchases, starting at $9.99 per 7 days. AI asks for nothing beyond the download.

AZ ships an update fortnightly, AI every 3 months. The most recent releases landed on October 9, 2026 and October 13, 2026 respectively.
