Verdict
The clearest difference is price: Cat Keyboard at Free against Mobile Diary's $1.99. Cat Keyboard also leads on update cadence (fortnightly vs every 6 weeks) and ratings volume (10 vs 2). Mobile Diary's advantage is in-app purchases (none vs 4) and rating (5.0 vs 4.7). On ads and device support there is nothing between them.
