Verdict

The call

Happy Scale and Weight Log both sit at 4.9 stars, but that hides the real split: 91% of Happy Scale's written reviews are positive against 43% of Weight Log's. Happy Scale also leads on update cadence (weekly vs every 2 months) and ratings volume (58K vs 57). Weight Log's advantage is monetization model (freemium vs subscription) and iOS requirement (13.0 vs 16.0). On price, rating, ads and in-app purchases there is nothing between them.
