# AZ vs AI

The clearest difference is review sentiment: AI at 50% against AZ's 0%. AI also leads on rating (5.0 vs 4.1) and ads (none vs shown). AZ's advantage is update cadence (weekly vs every 2 weeks) and iOS requirement (13.0 vs 15.1). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. AZ sells 1 one-off in-app purchase and AI sells 4 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AI holds the better App Store score, 5.0 against 4.1. Both are backed by a comparable volume of ratings — 9 and 8 respectively. Written reviews point the same way: 0% of AZ's written reviews are positive against 50% of AI's.

AZ ships an update weekly, AI every 2 weeks. The most recent releases landed on November 3, 2026 and November 8, 2026 respectively.
