# AZ vs AI

AZ and AI both sit at 5.0 stars, but that hides the real split: 50% of AI's written reviews are positive against 0% of AZ's. AI also leads on ads (none vs shown) and ratings volume (8 vs 1). AZ's advantage is iOS requirement (13.0 vs 15.1). On price, rating, update cadence and in-app purchases 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.

On the App Store both sit at effectively the same score — 5.0 for AZ against 5.0 for AI. That said, the two scores are not equally well evidenced: AI has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 0% of AZ's written reviews are positive against 50% of AI's.

AZ ships an update every 10 days, AI every 2 weeks. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
