Verdict

The call

The clearest difference is rating: Happy Scale at 4.9 against PopWeight's 3.8. Happy Scale also leads on update cadence (weekly vs every 2 months) and ratings volume (58K vs 23). PopWeight's advantage is monetization model (free with in-app purchases vs subscription) and iOS requirement (8.1 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.
