Verdict
The clearest difference is in-app purchases: SitStand Desk at none against Scale Ruler's 1. SitStand Desk also leads on iOS requirement (15.6 vs 17.0). Scale Ruler's advantage is update cadence (every 2 weeks vs every 6 months). On price, ads and device support there is nothing between them.
