Verdict
The clearest difference is rating: BelMetric at 5.0 against McMaster's 4.3. BelMetric also leads on update cadence (weekly vs every 5 weeks) and iOS requirement (13.0 vs 15.0). McMaster's advantage is ratings volume (220 vs 8). On price, ads, in-app purchases and monetization model there is nothing between them.
