Verdict
The clearest difference is rating: Weight Diary Lite at 4.8 against BMI Diary's 4.1. Weight Diary Lite also leads on in-app purchases (none vs 1) and ratings volume (7.3K vs 7). BMI Diary's advantage is update cadence (every 3 weeks vs every 6 months) and device support (4 vs 2). On price and ads there is nothing between them.
