Verdict
The clearest difference is in-app purchases: Diary AI at none against WillOS's 7. Diary AI also leads on price ($0.99 vs $3.99). WillOS's advantage is update cadence (every 2 weeks vs every 16 months) and iOS requirement (15.0 vs 17.0). On ads and device support there is nothing between them.
