Verdict
The clearest difference is monetization model: BMI Calculator・Weight Tracker at freemium against Happy Scale's subscription. BMI Calculator・Weight Tracker also leads on iOS requirement (14.0 vs 16.0). Happy Scale's advantage is update cadence (weekly vs every 2 months) and ratings volume (58K vs 508). On price, rating, review sentiment and ads there is nothing between them.
