Verdict
The clearest difference is rating: notesDiary at 5.0 against Audio Diary's 3.8. notesDiary also leads on iOS requirement (16.0 vs 18.0). Audio Diary's advantage is in-app purchases (none vs 2) and update cadence (every 3 days vs fortnightly). On price, review sentiment, ratings volume and ads there is nothing between them.
