Verdict
The clearest difference is price: Kipin at Free against Diary AI's $0.99. Kipin also leads on update cadence (every 3 weeks vs every 16 months) and iOS requirement (15.5 vs 17.0). Diary AI's advantage is in-app purchases (none vs 2) and ads (none vs shown). On device support there is nothing between them.
