Verdict

The call

The clearest difference is review sentiment: Happy Scale at 91% against Smart Scale's 19%. Happy Scale also leads on rating (4.9 vs 3.1) and update cadence (weekly vs every 2 months). Smart Scale's advantage is in-app purchases (none vs 8) and iOS requirement (8.0 vs 16.0). On price, ads and device support there is nothing between them.
