Verdict

The call

The clearest difference is in-app purchases: Z at none against Human Design's 10. Z also leads on ads (none vs shown). Human Design's advantage is update cadence (every 6 days vs every 2 months) and ratings volume (2.6K vs 517). On price, rating, review sentiment and device support there is nothing between them.
