# Zone 2 AI vs DeezSteps

The clearest difference is in-app purchases: DeezSteps at none against Zone 2 AI's 10. DeezSteps also leads on ads (none vs shown) and rating (5.0 vs 4.5). Zone 2 AI's advantage is ratings volume (134 vs 2). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Zone 2 AI sells 10 in-app purchases, starting at $3.99 per 7 days. DeezSteps asks for nothing beyond the download.

DeezSteps holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Zone 2 AI has 134 ratings behind it against 2, so its average is the more settled of the two.
